Project 1: LED Blinking


Difficulty: Easy


Let's start with a classic project that forms the foundation of Arduino programming – LED blinking. This project will introduce you to the basic concepts of setting up your Arduino board, writing code, and controlling output. You'll create a simple circuit where an LED turns on and off at regular intervals.


Materials Required

  1. Arduino board (any model)

  2. Breadboard

  3. LED (any color)

  4. Resistor (220Ω)

  5. Jumper wires


Steps


  1. Set up the circuit by connecting the LED and resistor in series to a digital pin on the Arduino.

  2. Write a simple Arduino sketch using the digitalWrite() function to control the LED.

  3. Upload the code to your Arduino board using the Arduino IDE.

  4. Watch as the LED blinks on and off according to your code.
