Arduino test cod: 
/ * 
  Blink 
  Turns on an LED on for two second, then off for two second, repeatedly. 
  
  This example code is in the public domain. 
 * / 

void setup () { 
  / / Initialize the digital pin as an output. 
  / / Pin 13 has an LED connected on most Arduino boards: 
  pinMode (13, OUTPUT); 
} 

void loop () { 
  digitalWrite (13, HIGH); / / set the LED on 
  delay (2000); / / wait for 2 second 
  digitalWrite (13, LOW); / / set the LED off 
  delay (2000); / / wait for 2 second
