Lab 1: LED Blink

Submitted by shaohan on Wed, 01/30/2013 - 15:49

Description:

This is an assignment of making a circuit to have LED light blink. I've changed the sample code from 1 second to 0.3 second.

 

Component used:

- Arduino UNO
- LED Red
- 220 Ohm Resistor


Code:

 

/*
  Blink
  Turns on an LED on for one second, then off for one second, repeatedly.
 
  This example code is in the public domain.
 */
 
// Pin 13 has an LED connected on most Arduino boards.
// give it a name:
int led = 13;
 
// the setup routine runs once when you press reset:
void setup() {                
  // initialize the digital pin as an output.
  pinMode(led, OUTPUT);     
}
 
// the loop routine runs over and over again forever:
void loop() {
  digitalWrite(led, HIGH);   // turn the LED on (HIGH is the voltage level)
  delay(300);               // wait for a second
  digitalWrite(led, LOW);    // turn the LED off by making the voltage LOW
  delay(300);               // wait for a second
}
