KS4018 Micro:bit Motor Driver Expansion Board

2025-02-19T05:43:30Z

Keyestudio: /* Add a library */

== Description ==

The Micro:bit motor drive expansion board contains a PCA9685PW chip and a TB6612FNG chip and so on. In order to save IO port resources, we use some pins of PCA9685PW chip to control the TB6612FNG motor chip. The TB6612FNG motor chip is used to control the rotation direction and speed of two DC gear motors.
It also integrates 2 RGB lights, 4 WS2812RGB lights, a buzzer with a P2.0 ultrasonic interface, a P2.0 IR sensor interface and a P2.0 tracking sensor interface. The output voltages of TXS0108EPWR level conversion IC interface is 5V.

== Parameters ==

* Input voltage: DC7-12V
* Output voltage: 5V
* Length, width and height: 92*64*15mm
* Weight (bare board): 41.8g

KS0328 Keyestudio HR-SR04 Blue Ultrasonic Module

2025-02-17T00:19:21Z

Keyestudio:

== Keyestudio HC-SR04 Blue Ultrasonic Module 3PCS ==

 [[File:Ks0328图片1.png|500px|frameless|thumb]] 

 

== Introduction ==
This kit includes three HC-SR04 ultrasonic modules. As the ultrasonic has strong directivity, slow energy consumption and far spread distance in the media, so it is commonly used in the measurement of distance, such as range finder and position measuring instrument. Using ultrasonic is more rapid, convenient, simple to calculate and more easier to achieve real-time control, so it has also been widely used in the development of mobile robots. 
Ultrasonic detector module can provide 2cm-450cm non-contact sensing distance, and its ranging accuracy is up to 3mm, very good to meet the normal requirements. The module includes an ultrasonic transmitter and receiver as well as the corresponding control circuit.

 
== Working Schematics ==
Please refer to the working sequence as below： 

 [[File:Ks0328图片2.png|700px|frameless|thumb]] 

* 1. First pull down the TRIG, and then trigger it with at least 10us high level signal;
* 2. After triggering, the module will automatically transmit eight 40KHZ square waves, and automatically detect whether there is a signal to return.
* 3. If there is a signal return, through the ECHO to output a high level, the duration time of high level is actually the time from emission to reception of ultrasonic.
 Test distance = high level duration * 340m/s * 0.5. 

 
== Parameters ==
* 1)Working Voltage: 0.5V(DC)
* 2)Working Current: 15mA
* 3)Detecting Range: 2-450cm
* 4)Detecting Angle: 15 degrees
* 5)Input Trigger Pulse: 10us TTL Level
* 6)Output Echo Signal: output TTL level signal (HIGH), proportional to range.

 
== Dimensions ==
 [[File:KS0328 (8).jpg|500px|frameless|thumb]] 

 
== Connection Diagram ==
 [[File:Ks0328图片3.png|800px|frameless|thumb]] 

 
== Test Code ==
Copy and paste the test code below to Arduino software: 
<pre>
int inputPin=4; // define ultrasonic signal receiver pin ECHO to D4
int outputPin=5; // define ultrasonic signal transmitter pin TRIG to D5
void setup()

{
Serial.begin(9600);
pinMode(inputPin, INPUT);
pinMode(outputPin, OUTPUT);
}

void loop()
{
digitalWrite(outputPin, LOW); delayMicroseconds(2);
digitalWrite(outputPin, HIGH); // Pulse for 10μ s to trigger ultrasonic detection
delayMicroseconds(10);
digitalWrite(outputPin, LOW);
int distance = pulseIn(inputPin, HIGH); // Read receiver pulse time
distance= distance/58; // Transform pulse time to distance
Serial.println(distance); //Output distance
delay(50);
}
</pre>

 
== Example Result ==
 [[File:Ks0328图片4.png|800px|frameless|thumb]] 
After upload well the code to UNO board, then open the serial monitor. When place an object in front of ultrasonic sensor (from near and far), it will detect the distance of object. You should see the value is displayed on the monitor shown below.

== How to Add a Library? ==

What are Libraries ? 
Libraries are a collection of code that makes it easy for you to connect to a sensor,display, module, etc. 
For example, the built-in LiquidCrystal library helps talk to LCD displays. There are hundreds of additional libraries available on the Internet for download. 
The built-in libraries and some of these additional libraries are listed in the reference. 

Here we will introduce the most simple way for you to add libraries . 
Step 1：After downloading well the Arduino IDE, you can right-click the icon of Arduino IDE. 
Find the option "Open file location" shown as below: 

 [[File:0085--200.png|500px|frameless|thumb]] 

Step 2: Enter it to find out libraries folder which is the library file of Arduino. 

 [[File:0428---81.png|800px|frameless|thumb]] 

Step 3：Next to find out the“libraries”of tank robot(seen in the link: https://fs.keyestudio.com/KS0428), you just need to replicate and paste into the libraries folder of Arduino IDE.

 [[File:图片1042801.png|800px|frameless|thumb]]

=== Project 1: LED Blink ===

'''(1)Description'''

For the starter and enthusiast, this is a fundamental program---LED Blink. 
LED, the abbreviation of light emitting diodes, consist of Ga, As, P, N chemical compound and so on. The LED can flash diverse color by altering the delay time in the test code. When in control, power on GND and VCC, the LED will be on if S end is high level; nevertheless, it will go off.

'''(2)Specification'''

 [[File:0428-47.png|500px|frameless|thumb]] 

* Control interface: digital port
* Working voltage: DC 3.3-5V
* Pin spacing: 2.54mm
* LED display color: red

'''(4) V5 Sensor Shield''' 
There will be troublesome when we combine Arduino development boards with numerous sensors. However, the V5 sensor shield, compatible with Arduino development board, address this problem perfectly. Just stack V5 board on it.
This sensor shield can be inserted into 3pin sensor modules and breaks out some some communication pins, like serial, IIC, and SPI communication as well.

'''Pins Description'''

delay(1000); // wait for a second
}
//****************************************************************

</pre>

'''(6) Test Result'''

(There will be contradict about serial communication between code and Bluetooth when uploading code, therefore, don’t link with Bluetooth module before uploading code.)
Upload the program on the development board, LED flicker with the interval of 1s.

 [[File:0428-50.png|500px|frameless|thumb]] 

'''(7)Code Explanation'''

pinMode(2，OUTPUT) - Set pin2 to OUTPUT

digitalWrite(2，HIGH) - When set pin2 to HIGH level(output 5V) or to LOW level(output 0V)

(8)Extension Practice
We succeed to blink LED. Next, let’s observe what LED will change if we modify pins and delay time.

'''Connection Diagram'''

 [[File:0428-51.png|500px|frameless|thumb]] 

We’ve altered pins and connected LED to D10.

Test Code:

<pre>

/*

*/
void setup() { // initialize digital pin 10 as an output.
pinMode(10, OUTPUT);
}
// the loop function runs over and over again forever
void loop() {
digitalWrite(10, HIGH); // turn the LED on (HIGH is the voltage level)
delay(100); // wait for 0.1 second
digitalWrite(10, LOW); // turn the LED off by making the voltage LOW
delay(100); // wait for 0.1 second
}
//****************************************************************

</pre>

The LED flickers faster than before through the test result, therefore, pins and delay time affect flash frequency.

=== Project 2: Adjust LED Brightness ===

(1)Description
In previous lesson, we control LED on and off and make it blink.
In this project, we will control LED brightness through PWM to simulate breathing effect. Similarly, you can change the step length and delay time in the code so as to demonstrate different breathing effect.
PWM is a means of controlling the analog output via digital means. Digital control is used to generate square waves with different duty cycles (a signal that constantly switches between high and low levels) to control the analog output.In general, the input voltage of port are 0V and 5V. What if the 3V is required? Or what if switch among 1V, 3V and 3.5V? We can’t change resistor constantly. For this situation, we need to control by PWM.

 [[File:0085=33.png|500px|frameless|thumb]] 

For the Arduino digital port voltage output, there are only LOW and HIGH, which correspond to the voltage output of 0V and 5V. You can define LOW as 0 and HIGH as 1, and let the Arduino output five hundred 0 or 1 signals within 1 second.
If output five hundred 1, that is 5V; if all of which is 1, that is 0V. If output 010101010101 in this way then the output port is 2.5V, which is like showing movie. The movie we watch are not completely continuous. It actually outputs 25 pictures per second. In this case, the human can’t tell it, neither does PWM. If want different voltage, need to control the ratio of 0 and 1. The more 0,1 signals output per unit time, the more accurately control.

(2) Specification

* Control interface: digital port
* Working voltage: DC 3.3-5V
* Pin spacing: 2.54mm
* Display color: red

int ledPin = 10; // Define the LED pin at D10
int value;

}
void loop ()
{
for (value = 0; value <255; value = value + 1)
{
analogWrite (ledPin, value); // LED lights gradually light up
delay (5); // delay 5MS
}
for (value = 255; value> 0; value = value-1)
{
analogWrite (ledPin, value); // LED gradually goes out
delay (5); // delay 5MS
}}//**********************************************************

</pre>

(6)Test Result 

Upload test code successfully, LED gradually becomes brighter then darker, like human breath, rather than light on and off immediately.

(7)Code Explanation

When we need to repeat some statements, we could use FOR statement. 
FOR statement format is shown below:

 [[File:0085=36.png|500px|frameless|thumb]] 

FOR cyclic sequence:
Round 1：1 → 2 → 3 → 4
Round 2：2 → 3 → 4
…
Until number 2 is not established, “for”loop is over,
After knowing this order, go back to code:
for (int value = 0; value < 255; value=value+1){
...
}
for (int value = 255; value >0; value=value-1){
...
}

The two“for”statements make value increase from 0 to 255, then reduce from 255 to 0, then increase to 255,....infinitely loop
There is a new function in the following ----- analogWrite()
We know that digital port only has two state of 0 and 1. So how to send an analog value to a digital value? Here,this function is needed. Let’s observe the Arduino board and find 6 pins marked“~”which can output PWM signals. 

Function format as follows:
analogWrite(pin,value)
analogWrite() is used to write an analog value from 0~255 for PWM port, so the value is in the range of 0~255. Attention that you only write the digital pins with PWM function, such as pin 3, 5, 6, 9, 10, 11. 
PWM is a technology to obtain analog quantity through digital method. Digital control forms a square wave, and the square wave signal only has two states of turning on and off (that is, high or low levels). By controlling the ratio of the duration of turning on and off, a voltage varying from 0 to 5V can be simulated. The time turning on(academically referred to as high level) is called pulse width, so PWM is also called pulse width modulation. 
Through the following five square waves, let’s acknowledge more about PWM. 

 [[File:0085=37.png|500px|frameless|thumb]] 

In the above figure, the green line represents a period, and value of analogWrite() corresponds to a percentage which is called Duty Cycle as well. Duty cycle implies that high-level duration is divided by low-level duration in a cycle. From top to bottom, the duty cycle of first square wave is 0% and its corresponding value is 0. The LED brightness is lowest, that is, turn off. The more time high level lasts, the brighter the LED. Therefore, the last duty cycle is 100%, which correspond to 255, LED is brightest. 25% means darker. 
PWM mostly is used for adjusting the LED brightness or rotation speed of motor. 
It plays vital role in controlling smart robot car. I believe that you can’t wait to enter next project. 

(8) Extension Practice：

Let’s modify the value of delay and remain the pin unchanged, then observe how LED changes.

=== Project 3: Photoresistor Sensor ===

 [[File:0428-56.png|200px|frameless|thumb]] 

(1)Description 

The photoresistor is a special resistor made of semiconductor materials such as CdS or Selenide septum. The surface is also coated with moisture-proof resin, which has a photoconductive effect. It is sensitive to ambient light. Its resistance varies from different light intensities. 

We use the characteristics of the photo-resistor to design the circuit and generate the photo-resistor module. 
Connecting the signal pin of photocell module to Analog port, when the stronger the light intensity, the greater the voltage of analog port, the greater the analog value is. 
On the contrary, the weaker the light intensity, the smaller the voltage of analog port, the smaller the analog value is.
Based on that, we can use the photocell module to read the analog value, so get the ambient light intensity.

=== Project 4: Servo Control ===

'''(1)Description'''

 [[File:Ks0194- servo.png|300px|frameless|thumb]] 

Servo motor is a position control rotary actuator. It mainly consists of housing, circuit board, core-less motor, gear and position sensor. Its working principle is that the servo receives the signal sent by MCU or receiver and produces a reference signal with a period of 20ms and width of 1.5ms, then compares the acquired DC bias voltage to the voltage of the potentiometer and obtain the voltage difference output. 

When the motor speed is constant, the potentiometer is driven to rotate through the cascade reduction gear, which leads that the voltage difference is 0, and the motor stops rotating. Generally, the angle range of servo rotation is 0° --180 °

The rotation angle of servo motor is controlled by regulating the duty cycle of PWM (Pulse-Width Modulation) signal. The standard cycle of PWM signal is 20ms (50Hz). Theoretically, the width is distributed between 1ms-2ms, but in fact, it's between 0.5ms-2.5ms. The width corresponds the rotation angle from 0° to 180°. But note that for different brand motor, the same signal may have different rotation angle.

 [[File:0428-69.png|500px|frameless|thumb]] 

The corresponding servo angles are shown below:
 [[File:0428-70.png|500px|frameless|thumb]] 

'''(2)Specification''' 

* Working voltage: DC 4.8V ~ 6V
* Operating angle range: about 180 ° (at 500 → 2500 μsec)
* Pulse width range: 500 → 2500 μsec
* No-load speed: 0.12 ± 0.01 sec / 60 (DC 4.8V) 0.1 ± 0.01 sec / 60 (DC 6V)
* No-load current: 200 ± 20mA (DC 4.8V) 220 ± 20mA (DC 6V)
* Stopping torque: 1.3 ± 0.01kg · cm (DC 4.8V) 1.5 ± 0.1kg · cm (DC 6V)
* Stop current: ≦ 850mA (DC 4.8V) ≦ 1000mA (DC 6V)
* Standby current: 3 ± 1mA (DC 4.8V) 4 ± 1mA (DC 6V)

Wiring note: the brown line of servo is linked with Gnd(G), the red line is connected to 5v(V) and orange line is attached to digital 9.

The servo have to be connected to external power, due to its high demand for driving servo current. Generally, the current of development board is not enough. If without connected power, the development board could be burnt.

=== Project 5: Ultrasonic Sensor ===

'''(1)Description'''

 [[File:0428-73.png|300px|frameless|thumb]] 

The HC-SR04 ultrasonic sensor uses sonar to determine distance to an object like bats do. It offers excellent non-contact range detection with high accuracy and stable readings in an easy-to-use package. It comes complete with ultrasonic transmitter and receiver modules. 
The HC-SR04 or the ultrasonic sensor is being used in a wide range of electronics projects for creating obstacle detection and distance measuring application as well as various other applications. Here we have brought the simple method to measure the distance with arduino and ultrasonic sensor and how to use ultrasonic sensor with arduino. 

'''(2)Specification'''

 [[File:0428-74.png|500px|right|frameless|thumb]] 

* Power Supply :+5V DC
* Quiescent Current : <2mA
* Working Current: 15mA
* Effectual Angle: <15°
* Ranging Distance : 2cm – 400 cm
* Resolution : 0.3 cm
* Measuring Angle: 30 degree
* Trigger Input Pulse width: 10uS

'''(3)Equipment'''

 [[File:0428-75.png|600px|frameless|thumb]] 

'''(4)The principle of ultrasonic sensor'''

As the above picture shown, it is like two eyes. One is transmitting end, the other is receiving end.

The ultrasonic module will emit the ultrasonic waves after trigger signal. When the ultrasonic waves encounter the object and are reflected back, the module outputs an echo signal, so it can determine the distance of object from the time difference between trigger signal and echo signal.
The t is the time that emitting signal meets obstacle and returns.
and the propagation speed of sound in the air is about 343m/s, therefore, distance = speed * time, because the ultrasonic wave emits and comes back, which is 2 times of distance, so it needs to be divided by 2, the distance measured by ultrasonic wave = (speed * time)/2

1.Use method and timing chart of ultrasonic module:
Setting the delay time of Trig pin of SR04 to 10μs at least, which can trigger it to detect distance.
2. After triggering, the module will automatically send eight 40KHz ultrasonic pulses and detect whether there is a signal return. This step will be completed automatically by the module.
3. If the signal returns, the Echo pin will output a high level, and the duration of the high level is the time from the transmission of the ultrasonic wave to the return.

(7)Test Result
Upload test code on the development board, open serial monitor and set baud rate to 9600. The detected distance will be displayed, unit is cm and inch. Hinder the ultrasonic sensor by hand, the displayed distance value is smaller.

 [[File:0428-86.png|500px|frameless|thumb]] 

(8)Code Explanation
int trigPin = 5; this pin is defined pin to transmit ultrasonic waves, generally output.
int echoPin = 4; this is defined as the pin of reception, generally input
cm = (duration/2) / 29.1; inches = (duration/2) / 74; by 0.0135
We can calculate the distance by using the following formula:
distance = (traveltime/2) x speed of sound
The speed of sound is: 343m/s = 0.0343 cm/uS = 1/29.1 cm/uS
Or in inches: 13503.9in/s = 0.0135in/uS = 1/74in/uS
We need to divide the traveltime by 2 because we have to take into account that the wave was sent, hit the object, and then returned back to the sensor.
(9)Extension Practice:
We have just measured the distance displayed by the ultrasonic. How about controlling the LED with the measured distance? Let's try it, connect an LED light module to the D10 pin.

=== Project 6: IR Reception ===

(1)Description 
There is no doubt that infrared remote control is ubiquitous in daily life. It is used to control various household appliances, such as TVs, stereos, video recorders and satellite signal receivers. Infrared remote control is composed of infrared transmitting and infrared receiving systems, that is, an infrared remote control and infrared receiving module and a single-chip microcomputer capable of decoding. 
The 38K infrared carrier signal emitted by remote controller is encoded by the encoding chip in the remote controller. It is composed of a section of pilot code, user code, user inverse code, data code, and data inverse code. The time interval of the pulse is used to distinguish whether it is a 0 or 1 signal and the encoding is made up of these 0, 1 signals. 
The user code of the same remote control is unchanged. The data code can distinguish the key. 
When the remote control button is pressed, the remote control sends out an infrared carrier signal. When the IR receiver receives the signal, the program will decode the carrier signal and determines which key is pressed. The MCU decodes the received 01 signal, thereby judging what key is pressed by the remote control. 
Infrared receiver we use is an infrared receiver module. Mainly composed of an infrared receiver head, it is a device that integrates reception, amplification, and demodulation. Its internal IC has completed demodulation, and can achieve from infrared reception to output and be compatible with TTL signals. Additionally, it is suitable for infrared remote control and infrared data transmission. The infrared receiving module made by the receiver has only three pins, signal line, VCC and GND. It is very convenient to communicate with arduino and other microcontrollers.

Below we have listed out each button value of keyestudio remote control. So you can keep it for reference. 

 [[File:0428-93.png|500px|frameless|thumb]] 

(7)Code Explanation 
irrecv.enableIRIn(): after enabling IR decoding, the IR signals will be received, then function“decode()”will check continuously if decode successfully. 

irrecv.decode(&results): after decoding successfully, this function will come back to “true”, and keep result in “results”. After decoding a IR signals, run the resume()function and receive the next signal

(There will be contradiction between serial communication of code and communication of Bluetooth when uploading code, therefore, don’t link with Bluetooth module before uploading code.) 
After uploading code on development board, then insert Bluetooth module, wait for the command from cellphone. 

(6)Download APP

Allow APP to access “location” in settings of your cellphone when connecting to Bluetooth module.

The code is reading the received signal, and we also need a stuff to send signal. In this project, we send signal to control robot car via cellphone. 
Then we need to download the APP. 

'''1.For iOS system'''

Enter APP STORE to search BLE Scanner 4.0, then download it.

 [[File:0428-98.png|300px|frameless|thumb]] 

'''2.For Android system'''

Enter Google Play to find out BLE Scanner, then download. 
And allow APP to access“location”, you could enable “location”in settings of your cellphone. 

 [[File:0428-99.png|300px|frameless|thumb]] 

* 3.After installation, open App and enable “Location and Bluetooth” permission.
* 4.We take iOS version as example. The operation method of Android version is almost same as it.
* 5.Scan Bluetooth module to get Bluetooth BLE 4.0. Its name is HMSoft.
Then click“connect”to link with Bluetooth and use it.

 [[File:0428-100.png|300px|frameless|thumb]] 

6. After connecting to HMSoft, click it to get multiple options, such as device information, access permission, general and custom service. Choose “CUSTOM SERVICE”

10.Open the serial monitor on Arduino，enter a 0 or other character at Text interface. 

 [[File:0428-105.png|300px|frameless|thumb]] 

Then click“Write”, open serial monitor to view if there is a “0” signal
 [[File:0428-106.png|300px|frameless|thumb]] 

(7)Code Explanation

Serial.available() : The current rest characters when return to buffer area. Generally, this function is used to judge if there is data in buffer. When Serial.available()>0, it means that serial receives the data and can be read 
Serial.read()：Read a data of a Byte in buffer of serial port, for instance, device sends data to Arduino via serial port, then we could read data by “Serial.read()”
(8)Extension Practice 
We could send a command via cellphone to turn on and off a LED. 
D10 is connected to a LED, as shown below:

=== Project 9: LED Expression Panel ===

(1)Description

 [[File:0428-120.png|700px|frameless|thumb]] 

If we add an expression panel to the robot, it will be amazing. Keyestudio's 8*16 dot matrix can meet your requirements. You can create facial expressions, patterns or other interesting displays yourself. 8*16 LED light board comes with 128 LEDs. The data of the microprocessor (arduino) communicates with the AiP1640 through the two-wire bus interface, so as to control the 128 LEDs on the module, which produce the patterns you need on dot matrix. To facilitate wiring, we also provide a HX-2.54 4Pin wiring.

(2)Specification

* Working voltage: DC 3.3-5V
* Power loss: 400mW
* Oscillation frequency: 450KHz
* Drive current: 200mA
* Working temperature: -40~80℃
* Communication method: two-wire bus

(3)Equipment

 [[File:0428-121.png|700px|frameless|thumb]] 

(4)8*16 Dot Matrix Display

Circuit Graphic

 [[File:0428-122.png|700px|frameless|thumb]] 

The principle of 8*16 dot matrix: 
How to control each led light of 8*16 dot matrix? We know that a byte has 8 bits, each bit is 0 or 1. When a bit is 0, turn off LED and when a bit is 0, turn on LED. Thereby, one byte can control the LED in a row of dot matrix, so 16 bytes can control 16 columns of led lights, that is, 8*16 dot matrix. 

Interface Description and Communication Protocol: 
The data of the microprocessor (arduino) communicates with the AiP1640 through the two-wire bus interface. 
The communication protocol diagram is shown below:
(SCLK) is SCL, (DIN) is SDA:

 [[File:0428-123.png|700px|frameless|thumb]] 

①The starting condition for data input: SCL is high level and SDA changes from high to low. 
②For data command setting, there are methods as shown in the figure below. 
In our sample program, select the way to add 1 to the address automatically, the binary value is 0100 0000 and the corresponding hexadecimal value is 0x40. 

 [[File:0428-124.png|700px|frameless|thumb]] 

③For address command setting, the address can be selected as shown below.
The first 00H is selected in our sample program, and the binary number 1100 0000 corresponds to the hexadecimal 0xc0

 [[File:0428-125.png|700px|frameless|thumb]] 

* ④The requirement for data input is that SCL is high level when inputting data, the signal on SDA must remain unchanged. Only when the clock signal on SCL is low level, the signal on SDA can be altered. The data input is low-order first, high-order is behind
* ⑤ The condition to end data transmission is that when SCL is low, SDA is low, and when SCL is high, the SDA level also becomes high.
* ⑥ Display control, set different pulse width, the pulse width can be selected as shown below
* In the example, we choose pulse width 4/16, and the hexadecimal corresponds to 1000 1010 is 0x8A

 [[File:0428-126.png|700px|frameless|thumb]] 

4. Introduction for Modulus Tool

The online version of dot matrix modulus tool:
http://dotmatrixtool.com/#

①Open links to enter the following page.

 [[File:0428-127.png|700px|frameless|thumb]] 

②The dot matrix is 8*16 in this project, so set the height to 8, width to 16, as shown below.

 [[File:0428-128.png|700px|frameless|thumb]] 

③ Generate hexadecimal data from the pattern
As shown below, press the left mouse button to select, the right button to cancel, draw the pattern you want, click Generate, and the hexadecimal data we need will be produced.

=== Project 10: Light Follow Robot ===

(1)Description

[[File:0428-137.png|500px|frameless|thumb]] 

We’ve introduce how to use various sensors, modules. 
In this lesson, we combine with hardware knowledge -- photoresistor module, motor driving, to build a light-following robot! 
Just need to use 2 photoresistor modules to detect the light intensity at the both side of robot. Read the analog value to rotate the 2 motors, thus drive the tank robot run. 

The specific logic of light following robot is shown as the table below: 

[[File:0428-133.png|500px|frameless|thumb]] 

[[File:0428-134.png|500px|frameless|thumb]] 

We make a flow chart based on the above logic table, as shown below:

(2)Connection Diagram

[[File:04288-24.png|500px|frameless|thumb]] 

Hook-up Attention:
The 4Pin terminal block is marked with silkscreen 1234. The red line of right rear motor is connected to terminal 1, black line is linked with end 2. The red line of left front motor is attached to terminal 3, black line is linked with port 4.

=== Project 13: IR Remote Robot Tank ===

[[File:0428-148.png|500px|frameless|thumb]] 

'''(1)Description'''

IR remote control is one of most ubiquitous control, applied in TV, electric fan and some household appliances. In this project, we will make an IR remote smart car. And we’ve known every key value on IR remote control. Thus, we could control smart car via and display the patterns on dot matrix via corresponding key value

The specific logic of infrared remote control robot is shown below:

'''(3)Connection Diagram'''

[[File:04288-27.png|500px|frameless|thumb]] 

Attention：GND,VCC, SDA, SCL of 8x16 LED panel are respectively linked with -（GND), +（VCC), SDA ,SCL. And “-”、“+” and S of IR receiver module are attached to G（GND), V（VCC) and A0 on sensor shield. On the condition of insufficient digital ports, the analog ports can be treat as digital ports. A0 equals to digital 14, A1 is like digital 15.
