.thumbnail.JPG "Breadboard and Arduino")
Description
Use the Arduino to control a light emitting diode and make it blink on for a second, then off for seven seconds.
Components Used
- Light Emitting Diode (LED)
- Resistor
Arduino Code
/*
Blink
Turns on an LED on for one second, then off for seven seconds, 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(1000); // wait for a second
digitalWrite(13, LOW); // set the LED off
delay(7000); // wait for seven seconds
}
