See   for detailed specifications, overviews, schematics, etc. Core functions, code examples, and links to many of the device libraries can be found in the learning section; refer to the manufacturer's site if using other add-on shields or sensors.
The latest Arduino Integrated Development Environment (IDE) necessary for programming your UNO R3 board can be obtained at  
http://arduino.cc/en/Main/Software (the Download menu choice on Arduino.cc)

Examples for many basic components can be found under the Examples menu. As you install libraries for additional shields, new examples may be available.
Follow the getting started guide found on the arduino.cc web site. Click Learning, and select Getting started. Click on the link for Windows, Mac OS X, or Linux for more specific directions.

4. Getting Started

1. Download the Arduino Environment (IDE) and install or unzip/extract the application directory.
2. Connect the UNO board to one of your computer's USB port.

4. Launch the Arduino IDE application
5. Open a sketch example such as "Blink"
6. Select your Board from the Tools menu.
7. Select the Serial Port used by the board
8. Upload the sketch to the board

5. Project Details

Project 1: Hello World


As for starters, we will begin with something simple. In this project, you only need an Arduino and a USB cable to start the "Hello World!" experiment. This is a communication test of your Arduino and PC, also a primer project for you to have your first try of the Arduino world!

Hardware Required:
1. Arduino board x1
2. USB cable x1

Sample program:
After installing driver for Arduino, let's open Arduino software and compile code that enables Arduino to print "Hello World!" under your instruction. Of course, you can compile code for Arduino to continuously echo "Hello World!" without instruction. A simple If () statement will do the instruction trick. With the onboard LED connected to pin 13, we can instruct the LED to blink first when Arduino gets instruction and then print "Hello World!”.

int val;//define variable val
int ledpin=13;// define digital interface 13
void setup()
  Serial.begin(9600);// set the baud rate at 9600 to match the software set up. When connected to a specific device, (e.g. bluetooth), the baud rate needs to be the same with it.
  pinMode(ledpin,OUTPUT);// initialize digital pin 13 as output. When using I/O ports on an Arduino, this kind of set up is always needed.
void loop()
  val=Serial.read();// read the instruction or character from PC to Arduino, and assign them to Val.
  if(val=='R')// determine if the instruction or character received is “R”.
  {  // if it’s “R”,    
    digitalWrite(ledpin,HIGH);// set the LED on digital pin 13 on. 
    digitalWrite(ledpin,LOW);// set the LED on digital pin 13 off.    delay(500);
    Serial.println("Hello World!");// display“Hello World!”string.

Click serial port monitor,Input R,LED 13 will blink once,PC will receive information from Arduino: Hello World
After you choose the right port, the experiment should be easy for you!

Project 2: LED Blinking

Introduction: Blinking LED experiment is quite simple. In the "Hello World!" program, we have come across the LED. This time, we are going to connect an LED to one of the digital pins rather than using LED13, which is soldered to the board. Except for an Arduino and a USB cable, we will need extra parts as below.

Hardware Required:
1.Uno R3 board *1
2.USB Cable *1
3. Red M5 LED*1
4. 220Ω resistor*1
5 Breadboard*1
6. Breadboard jumper wires* several
We follow the below diagram from the experimental schematic link. Here we use digital pin 10. We connect LED to a 220 ohm resistor to avoid high current damaging the LED.

Connection Diagram:


Sample Code:

According to the above circuit, you can start compiling the program, turning the LED 1 second on and 1 second off. This program is simple and similar to one that comes with Arduino except it’s connected to digital pin 10.

int ledPin = 10; // define digital pin 10.
void setup()
pinMode(ledPin, OUTPUT);// define pin with LED connected as output.
void loop()
digitalWrite(ledPin, HIGH); // set the LED on.
delay(1000); // wait for a second.
digitalWrite(ledPin, LOW); // set the LED off.
delay(1000); // wait for a second

After downloading this program, in the experiment, you will see the LED connected to pin 10 turning on and off, with an interval approximately one second.
The blinking LED experiment is now completed.

Project 3:Traffic Light


In the previous program, we have done the LED blinking experiment with one LED. Now, it’s time to up the stakes and do a bit more complicated experiment-traffic lights. Actually, these two experiments are similar. While in this traffic lights experiment, we use 3 LEDs with a different colour other than 1 LED.

Hardware Required:
1. Unor3 board *1
2. USB cable *1
3. Red M5 LED*1
4. Yellow M5 LED*1
5. Green M5 LED*1
6. 220Ω resistor *3
7. Breadboard*1
8. Breadboard jumper wires* several

Connection Diagram:

With the above parts ready, we can get started. We can refer to the LED blinking experiment for this one. Below is a sample schematic diagram. Pins we use are digital pin 10, 7 and 4.

Sample Code:
Since it is a simulation of traffic lights, the blinking time of each LED should be the same with those in traffic lights system. In this program, we use Arduino delay () function to control delay time, which is much simpler than C language.

int redled =10; // initialize digital pin 8.
int yellowled =7; // initialize digital pin 7.
int greenled =4; // initialize digital pin 4.
void setup()
pinMode(redled, OUTPUT);// set the pin with red LED as “output”
pinMode(yellowled, OUTPUT); // set the pin with yellow LED as “output”
pinMode(greenled, OUTPUT); // set the pin with green LED as “output”
void loop()
digitalWrite(greenled, HIGH);//// turn on green LED

delay(5000);// wait 5 seconds
digitalWrite(greenled, LOW); // turn off green LED
for(int i=0;i<3;i++)// blinks for 3 times
delay(500);// wait 0.5 second
digitalWrite(yellowled, HIGH);// turn on yellow LED
delay(500);// wait 0.5 second
digitalWrite(yellowled, LOW);// turn off yellow LED
delay(500);// wait 0.5 second
digitalWrite(redled, HIGH);// turn on red LED
delay(5000);// wait 5 second
digitalWrite(redled, LOW);// turn off red LED

When the uploading process is completed, we can see the traffic lights of our own design.

Note: this circuit design is very similar to the one in LED chase effect.
The green light will be on for 5 seconds, and then off., followed by the yellow light blinking for 3 times, and then the red light on for 5 seconds, forming a cycle. The cycle then repeats.
The experiment is now completed, thank you.

Project 4: LED chasing Effect


We often see billboards composed of colourful LEDs. They are constantly changing to form various patterns. In this experiment, we compile a program to simulate chase effect.

Hardware Required:
1. Uno R3 board *1
2.USB Cable *1
3.Red M5 LED*2 4.Yellow M5 LED*2
5.Blue M5 LED*2
6.220Ω Resistor *6
8. Breadboard jumper wires* several

Connection Diagram:

According to the wiring method of diodes, six LEDs are connected to digital 2~7 pins. As shown in fig.: LED chase effect wiring circuit:
