Programming software installation guide

1. Download and install the latest arduino IDE from arduino official

webside---http://arduino.cc/

2. Enter the installation directory for example

“D:\arduino-1.5.2\hardware\arduino\avr\libraries” ,then put our device and sensor

library into the installation.

3. Open arduino IDE，you can find the library and example.

Programming software user manual

Double-click software icon on the desktop:

menu bar

File menu

File menu contains the a few options,we need to know “Examples”and”Preferences”.

Click examples and select a project to help you.

Click Preferences and open a dialog,

Sketchbook location

The default sketch file storage path.

Editor language

Choose a language for you.

Tools menu

Serial Monitor

You can use it send and receive serial data.

ArduBlock

A visual flowchart editor that can generate C code .

Board

Select the type of the board connected, we chose Arduino Leonardo.

Write a simple program

Create an empty program. Click "File" - "New", the software creates a new window:

The software will automatically generate the following code:

void setup() {

// put your setup code here, to run once:

}

void loop() {

// put your main code here, to run repeatedly:

}

Add the following code

const int analogInPin = A0; /*Define a constant of the analog input port number*/

int sensorValue = 0; /*Define a variable of the analog input value */

void setup() { // put your setup code here, to run once:

Serial.begin(9600); /*Serial port initialization, baud rate 9600*/

}

void loop() { // put your main code here, to run repeatedly:

sensorValue = analogRead(analogInPin);/*Read the analog input value*/

Serial.print("sensor = " );/*Serial port send string*/

Serial.print(sensorValue); /*Serial port send number*/

Serial.print("\n" ); /*Serial port send Character*/

delay(1000); /*The number of milliseconds, delay one second here*/

}

Use usb cable to connect pc and mainboard.

Click the button on the toolbar to compile ，after that click to download

the program.

Click the serial monitor button on the toolbar , or click on "Tools" - "Serial

Monitor" to open the serial port monitor.

Mainboard programming examples

Anolog input

The port for input :A0，A1，A2，A3，A4，A5，A6，A7，A8，A9.

Connecting devices

Connect the light sensor to the anolog port A0 by a 3-pin wire.

Code int analog_val=0;

void setup() {

// put your setup code here, to run once:

}

void loop() {

// put your main code here, to run repeatedly:

analog_val = analogRead(A0);

}

Digital input

The port for input : D0，D1，D2，D3，D4，D5，D6，D7，D8，D9.

Connecting devices

Connect the touch sensor to the digital port D3 by a 3-pin wire.

Code int digital_val=0;

void setup() {

// put your setup code here, to run once:

pinMode(3, INPUT);

}

void loop() {

// put your main code here, to run repeatedly:

digital_val = digitalRead(3);

}

Digital output

The port for output : D0，D1，D2，D3，D4，D5，D6，D7，D8，D9.

We use a RJ11 adapter to connect RJ11 interface sensors.

Connecting devices

Connect the LED board to the digital port D3 by RJ11 cable.

Code void setup() {

pinMode(3, OUTPUT);

}

void loop(){

digitalWrite(3, HIGH);

delay(1000);

digitalWrite(3, LOW);

delay(1000);

}

PWM output

The port for PWM : D3，D5，D6，D9.

Connecting devices

Connect the LED board to the digital port D3 by RJ11 cable.

Code void setup() {

pinMode(3, OUTPUT);

}

void loop() {

for (int i = 0; i < 255; i++) {

analogWrite(3, i);

delay(5);

}

delay(5);

}

Motor control

Connecting devices

Code

#include <Motor.h>

void setup() {

motor.init();

}

void loop() {

motor.run(50,50);

delay(1000);

motor.setMoto(0,0);

delay(1000);

motor.stop();

delay(1000);

}

Compound eyes

Connecting devices

Code #include <Eye.h>

int min_value;

int min_index;

int max_value;

int max_index;

int single_value;

void setup() {

}

void loop() {

min_value = eye.minValue();

min_index = eye.minIndex();

max_value = eye.maxValue();

max_index = eye.maxIndex();

single_value = eye.singleValue(0);

}

TFT screen

Connecting devices

Code #include <TFT.h>

int cnt=0;

void setup() {

tft.init();

}void loop() {

tft.printf(0,"hello\ncnt=%d\n",cnt);

tft.printf(9,"printf in line 9\n");

cnt++;

}
