See http://arduino.cc 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.
3. Install the drivers (If the computer does not automatically download and install the necessary USB drivers, point the hardware setup to the "drivers" directory of the Arduino IDE application.)
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: LED Blinking
Introduction:
Blinking LED experiment is quite simple. In the "Hello World!" program, we have come across 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 an Arduino and an USB cable, we will need extra parts as below.
Hardware Required:
1. Unor3 Board *1
2. Red M5 LED*1
3. 220Ω Resistor*1
4. Breadboard*1
5. Breadboard Jumper Wires* several
We follow 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
}
}
==Result ==
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.
