Description：

When it comes to programming, many think it difficult. However, KEYES group issues a smart RV kit to cope with this problem.
This is low cost, easy-to-build and open source programming kit-----smart RV.
It integrates smart home and robot car. In addition, it helps you absorb the knowledge of programming like electronics, control logic and computing and science.
In compliance with the tutorial, you can create your own robot by boards, slot connection and wiring. In the assembly process, the detailed projects will guide you to learn the working principle of sensors and modules.
What’s more, it a has temperature humidity sensor and an LCD display except LED, line tracking sensor, ultrasonic sensor, Bluetooth module and motor driving modules.
Should you are interested in STEM and code programming, you can customize your RV by altering code and adding extra modules. That sounds entertaining, right? Let’s get started1

Kit

Remember to check if the components received are in line with the following product list when you getting this kit.

Getting Started with Arduino

Installing Arduino IDE

When we get control board, we need to download Arduino IDE and driver firstly. You could download Arduino IDE from the official website:
https://www.arduino.cc/, click the SOFTWARE on the browse bar, click“DOWNLOADS” to enter download page, as shown below:

You can download either Windows win7 and newer or Windows ZIP file.
The first one doesn’t require

There are two versions of IDE for WINDOWS system, you can choose from the Installer (.exe) and the Zip packages. We suggest you use the first one that installs directly everything you need to use the Arduino Software (IDE), including the drivers.
With the Zip package you need to install the drivers manually. The Zip file is also useful if you want to create a portable installation.

You just need to click JUST DOWNLOAD.

Keyestudio MEGA 2560 Smart Development Board

We need to know keyestudio MEGA 2560 development board, as a core of this smart car.

The processor core of MEGA 2560 board is ATMEGA2560-16AU, with the cp2102 chip.
It has 54 digital input/output pins (of which 15 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, 1 ICSP header, and a reset button.
It can be interfaced computer with external power with a USB cable.

Install Driver on Windows System

Let’s install the driver of keyestudio MEGA 2560 smart development board. The USB-TTL chip on this board adopts CP2102 serial chip. The driver program of this chip is included in Arduino 1.8 version and above, which is convenient. Plugged in USB port, the computer can recognize the hardware and automatically install the driver of CP2102.

If install unsuccessfully, or you intend to install manually, open the device manager of computer. Right click Computer----- Properties----- Device Manager.

There is a yellow exclamation mark on the page, which implies installing unsuccessfully. Then we double click the hardware and update the driver.

Click “OK” to enter the following page, click“browse my computer for updated driver software”, find out the installed or downloaded ARDUINO software. As shown below:

There is a DRIVERS folder in Arduino software installed package. Just open driver folder and you can see the driver of CP210X series chips.

We click “Browse”, then find out the driver folder, or you could enter “driver” to search in rectangular box, then click“next”, the driver will be installed successfully. (I place Arduino software folder on the desktop, you can follow my way)

Open device manager, we will find the yellow exclamation mark disappear. The driver of CP2102 is installed successfully.

Install Driver on MAC System

The USB to serial chip of control board is CP2102. We install driver on MAC as follows: https://wiki.keyestudio.com/How_to_Install_the_Driver_of_CP2102_on_MAC_System

Arduino IDE Setting

Click icon，open Arduino IDE.

To avoid the errors when uploading the program to the board, you need to select the correct Arduino board that matches the board connected to your computer. Then come back to the Arduino software, you should click Tools→Board, select the board. (as shown below)

Then select the correct COM port (you can see the corresponding COM port after the driver is successfully installed)

Before uploading the program to the board, let’s demonstrate the function of each symbol in the Arduino IDE toolbar.

• A- Used to verify whether there is any compiling mistakes or not.
• B- Used to upload the sketch to your Arduino board.
• C- Used to create shortcut window of a new sketch.
• D- Used to directly open an example sketch.
• E- Used to save the sketch.
• F- Used to send the serial data received from board to the serial monitor.

Note: the setting method on Mac system is same as on Windows system except different COM port, as shown below:

Start First Program

We’ve known how to download and install the driver of development board , next, we will burn a code to show“Hello World！”in the monitor.

Test Code

void setup() {
  // initialize serial communication at 9600 bits per second:
  Serial.begin(9600);   
}

void loop() {
  // print out "Hello world!"
  Serial.println("Hello world!");
  delay(1000);// delay 1 second
}

Open Arduino IDE, and set board as follows:

Set COM port, as shown below:

Click to start compiling the program, and check errors.
Click to upload the program, upload successfully.

Upload the program successfully, open serial monitor and set baud rate to 9600. Monitor will print“Hello World!”each 1s.
Congratulation, you finish the first program.

Projects

For detailed projects, nevigated the website https://fs.keyestudio.com/KS0507

The whole project begins with basic program. Starting from simple to complex, the lessons will guide you to assemble smart RV and absorb the knowledge of electronic and machinery step by step. I reckon that you might hardly sit still and itch to have a go, let’s get started.

Note: (G), marked on each sensor and module, is negative pole and connected to“G”,“-”or“GND”on the sensor shield or control board ; (V) is positive pole and interfaced with“V”,“VCC”,“+”or“5V”on the sensor shield or control board.

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. It is often applied to numbers and text display as an indicator in the circuit.

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) Parameter：

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