1/26 Lab: Blinking LED
Description
Use the Arduino to control a light emitting diode and make it blink in different rate.
Components Used
- Light Emitting Diode (LED)
- Resistor
Arduino Code:
/*
Blink
2 LEDs blink for 1 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);
pinMode(12, OUTPUT);
}
void loop() {
digitalWrite(13, HIGH); // set the LED on
delay(1000); // wait for a second
digitalWrite(13, LOW); // set the LED off
digitalWrite(12,HIGH); // set 2nd LED on
delay(1000); // wait for a second
digitalWrite(12,LOW); //set 2nd LED off
}
