Components Used:
LED, 220 ohm resistor, arduino board.
Arduino Code:
//This LED turn on for 1 second and then turn off for 0.2 second in a loop.
void setup() {
// initialize the digital pin as an output.
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(200); // wait for a 0.2 second
}
