Blink
Description
Use the Arduino to control a light emitting diode and make it blink in a random rate between .1 and 1 seconds.
Components Used
- Light Emitting Diode (LED)
- Resistor
Arduino Code
Based on Blink from Arduino Examples
/*
Blink
Turns on an LED on for one second, then off for one 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(random(100,1000)); // wait for between .1 and 1 second
digitalWrite(13, LOW); // set the LED off
delay(random(100,1000)); // wait for between .1 and 1 second
