Intro to Arduino“Hardy Friend”
• Arduino– http://arduino.cc/
• Specifically, the UNO– http://arduino.cc/en/Main/ArduinoBoardUno
• Getting Started– http://arduino.cc/en/Guide/Windows
• Blink– http://arduino.cc/en/Tutorial/Blink
• /*• Blink• • Turns on an LED on for one second, then off for one second, repeatedly.• • The circuit:• * LED connected from digital pin 13 to ground.• • * Note: On most Arduino boards, there is already an LED on the board• connected to pin 13, so you don't need any extra components for this example.• • • Created 1 June 2005• By David Cuartielles• • http://arduino.cc/en/Tutorial/Blink• • based on an orginal by H. Barragan for the Wiring i/o board• • This example code is in the public domain.
• • */
• int ledPin = 13; // LED connected to digital pin 13
• // The setup() method runs once, when the sketch starts
• void setup() { • // initialize the digital pin as an output:• pinMode(ledPin, OUTPUT); • }
• // the loop() method runs over and over again,• // as long as the Arduino has power
• 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• }
A good first program to download and run
