3. Application of Arduino
Introduction
What’s Arduino? Arduino is an open-source hardware project platform. This platform includes a circuit board with simple I/O function and program development environment software. It can be used to develop interactive products. For example, it can read signals of multiple switches and sensors, and control light, servo motor and other various physical devices. It’s widely applied in robot field.
4. Arduino installation and program upload
First, download Arduino development software, click below hyperlink:
https://www.arduino.cc/en/Main/OldSoftwareReleases#1.5.x
Downloaded file is an arduino-1.5.6-r2-windows.zip compressed folder, and unzip it to your hard drive.
Double click Arduino-1.5.6 .exe. and select “I agree”.
Click “Next”.
And then “Install”.
Wait for the installation to be completed, and click close.
Below is how Arduino 1.5.6 looks like.
Next, let’s install Arduino driver.
For different operating system, there may be slight difference in installation method. Below is an example in WIN 7.
When you connect Arduino Uno to your computer the first time, right click “Computer” —> “Properties”—> “Device manager”, you can see “Unknown devices”.
Click “Unknown devices”, select “Update Driver software”.
In this page, click “Browse my computer for driver software”.
Find the “drivers” file.
Click “Next”; select “Install this driver software anyway” to begin the installation.
Installation completed; click “Close”.
After driver is installed, go to “Device manager” again. Right click “Computer” —> “Properties”—> “Device manager”, you can see UNO device as below figure shows, also the Com port info.
Following is a sketch uploading example called “Hello World！”.
First, open Arduino IDE. In this example sketch, we program Arduino to display “Hello World！” in serial monitor when it receives a specific character string “R”; also the on-board D13 LED will blink once each time it receives “R”.
First, set up board; In “Tools”, select “Arduino Uno”.
Next, set up COM port; In “Tools”, select “COM3”.
After selection, you can see indicated area is the same with settings in “Device manager”.
Copy the example sketch and paste it to the IDE; click “Verify ” to check compiling mistakes; click “Upload ” to upload the program to the board.
After uploading is done, open “serial monitor ”; enter “R”; click “Send”, the serial monitor will display “Hello World!” and the D13 LED will blink once.
Congratulations! Your first sketch uploading is a success!

5. Introduction of ArduBlock
Ardublock, developed by Shanghai Xinchejian, is a graphical programming environment software. ArduBlock is a third-party software of Arduino’s official programming environment. It can only work with Arduino software. Different from Arduino's text-based programming environment, it's in graphical form. Programming is like building blocks, which makes programming more visualized and interactive. It also greatly lowers the difficulties in programming. People with no programming experience can also compile a program for Arduino controller.

Figure pin 13 is used as prompt, so when making a sound , LED blinks. “Dang”module is a cycle structure on condition that the value of t1 is less than 5000. When more than 5000, the cycle structure ends. Please have a try, to find in which frequency the sound is sweeter from 10 to 5000 in this mystical sound program.

Project 18: Reed Switch Module
Introduction:
The reed switch grass tube is full of highly purified inactive gas. Before operating, the two reeds are separated. Extra magnetic field produces different polarity around the endpoint of the two reeds, so that two different polar reeds attract each other and close.
In this project, we use graphical programming and regard reed switch module and magnet as a switch to control the on and off of LED.
Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Piranha LED*1
4. Reed Switch Module*1
5. Female to Female Dupont Line*6
Connection Diagram:
After wiring, we can start programming.

Project 19: Human Body IR Pyroelectricity
Introduction:
It is a human body detecting sensor based on infrared pyroelectricity, which can only detect moving body. That is to say, when you don’t move, it can do nothing. Still ,it is a digital sensor.
In this project, we use graphical programming and regard human body IR pyroelectricity and human body as a button to control the on and off of LED.
Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Piranha LED*1
4. Human Body IR Pyroelectricity*1
5. Female to Female Dupont Line*6
Connection Diagram:
After wiring, we can start programming.

Sample Code:
*****************************************************************************
void setup()
{
pinMode( 3 , INPUT);
Serial.begin(9600);
pinMode( 6 , OUTPUT);
}
void loop()
{
if (( digitalRead(3) && HIGH ))
{
Serial.print("Somebody is in this area!");
Serial.println();
digitalWrite( 6 , LOW );
delay( 1000 );
}
else
{
Serial.print("No one!");
Serial.println();
digitalWrite( 6 , HIGH );
delay( 1000 );
}
}
*******************************************************************************
Result:
After the downloading is done, use reed switch module to check whether there is someone moving. If someone moving, piranha LED on and the serial monitor indicates “Somebody is in this area!”; if nobody moving, the LED off and the serial monitor indicates "No one!".
Project 20: Line Tracking Sensor
Introduction:
Line tracking sensor has a TCRT5000 photoelectric sensor. Infrared reflectivity of color is different ,which is applied to convert strong and weak echoed signal into current signal by photoelectric sensor. The potentiometer is used to adjust sensitivity of this sensor.
In this project, we use graphical programming to detect high and low level of line tracking sensor signal port and the color of objects, displaying it on serial monitor.
Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. Line Tracking Sensor*1
4. Female to Female Dupont Line*3
Connection Diagram:
After wiring, we can start programming.

Serial.print(digitalRead(3));
Serial.println();
delay( 1000 );
}
*******************************************************************************
Result:
After downloading program, we can use line tracking sensor to detect the color of line tracking object. If it is white, the light on the sensor turns on, and display “Line Tracking0” on serial monitor；if black, the light off, and display “Line Tracking1”
Project 21: MQ-2 Combustible Gas and Smoke Sensor
Introduction:
Arduino MQ-2 combustible gas sensor is mainly used to detect whether the gas leaks in industry and family. It can detect liquefied petroleum gas, methane, ethane, iso-butane, ethyl alcohol, hydrogen, smoke and ect. Potentiometer can be used to adjust the sensitivity of the sensor.
In this project, we use graphical programming to detect analog value of signal port of this sensor. When gases leak, the value increases and the LED is on .
Materials Required:
1. KEYESTUDIO UNO Control Board *1
2. V5 Sensor Shield*1
3. MQ-2 Combustible Gas and Smoke Sensor*1
4. Female to Female Dupont Line*3
Connection Diagram:
After wiring, we can start programming.

}
*******************************************************************************
Result:
After downloading program, you can use this sensor to detect whether the gas leaks. Open serial monitor, you can see the analog value of ambient gas. In this experiment, we detect the gas of a lighter. Open a lighter and close to the sensor after closing it, the analog increasing, and the red light on the sensor is on; the lighter away from this sensor, the analog value decreasing, the red light off.
Project 22: Soil Module
Introduction:
This is an easy moisture sensor detecting the moisture of soil. If soil is lack of water, the output analog value decreases; if not, the value increases.
