Arduino Interface – LED

This article is a continuation of the series on “Arduino Interface – LED” and carries the discussion on Turn ON/OFF, and blinking of LED in the Arduino Environment.

  • LED (light-emitting diode): LED is a simple diode that emits light in a forward bias
  • Arduino: is an open-source, board that has a Microchip ATmega328P microcontroller on it.

Pre-Request

  • PC
  • Arduino IDE setup or web-based IDE

Components Required

  • LED – 1 Nos,
  • Resistor, 220 Ohm – 1Nos
  • Breadboard (Optional: If required)
  • Arduino UNO
  • Jumper wires

Turn On/Off LED

The program simply turns ON and OFF LED with some delay between them.

  • For Turn OFF LED – Set digital pin Low digitalWrite(LED_BUILTIN, LOW);
  • For Turn ON LED – Set digital pin high digitalWrite(LED_BUILTIN, HIGH);
