INTRODUCTION TO THE ARDUINO

Arduino is a single-board micro controller that is open-source, derived from the Wiring platform, designed to facilitate the use of electronics in various fields. Atmel AVR processor has hardware and software has its own programming language.

history

This project began in Ivrea, Italy in 2005. Now it has more than 120,000 units sold. Massimo Banzi and its founders are David Cuartielles.


program example :

#define LED_PIN 13
 
void setup () {
    pinMode (LED_PIN, OUTPUT);     // enable pin 13 for digital output
}
 
void loop () {
    digitalWrite (LED_PIN, HIGH);  // turn on the LED
    delay (1000);                  // wait one second (1000 milliseconds)
    digitalWrite (LED_PIN, LOW);   // turn off the LED
    delay (1000);                  // wait one second
}

 Arduino-compatible boards



Because the design of hardware and software are open-source Arduino, 

other manufacturers are free to imitate, for example:

1.     Freeduino
2.     Cosmo Black Star
3.     Freeduino MaxSerial
4.     Zigduino
