Description:
To familiarize ourselves with building circuits and the Arduino hardware/software. In this lab, we use the Arduino micro-controller to control an LED and make it blink at different rates, depending on what we code.
 
Components Used:
  • LED
  • Arduino Micro-controller
  • Resistor
  • Wires/Bread Board
 
Arduino Code:
/*
 ** Blink **
 * Turns an LED on and off with varying time(different speeds depending on what we code) repeatedly.
 * In this case, it is on for .5 sec and off for 1.25 sec.
 *   -- Taken from the Blink example --
 */
 
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(500);              // wait for .5 second (LED on)
  digitalWrite(13, LOW);    // set the LED off
  delay(1250);              // wait for 1.25 seconds (LED off)
}
LED On
LED Off
