Description

I used Arduino with a red LED. I edited the sketch code to turn on the LED for 10 seconds and then off for 2 seconds. Uploaded the code and took pictures of the result.

Components

  • 1 Arduino
  • 1 LED
  • 1 Resistor (220Ω)
  • 1 Breadboard

Code

/*
 Blink
 Turns on an LED on for one second, then off for one second, repeatedly.

Most Arduinos have an on-board LED you can control. On the Uno and
 Leonardo, it is attached to digital pin 13. If you're unsure what
 pin the on-board LED is connected to on your Arduino model, check
 the documentation at http://www.arduino.cc

This example code is in the public domain.

// the setup function runs once when you press reset or power the board
void setup() {
 // initialize digital pin 13 as an output.
 pinMode(13, OUTPUT);
}

// the loop function runs over and over again forever
void loop() {
 digitalWrite(13, HIGH); // turn the LED on (HIGH is the voltage level)
 delay(10000); // wait for a second
 digitalWrite(13, LOW); // turn the LED off by making the voltage LOW
 delay(2000); // wait for a second
}
