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


  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.

Project 2: Traffic Light Controller

Difficulty: Easy

In this project, you'll simulate a traffic light system using LEDs. This will give you a hands-on understanding of how to control multiple outputs and create a primary timing mechanism.

Materials Required

  1. Arduino board

  2. Breadboard

  3. Red, yellow, and green LEDs

  4. Resistors (220Ω)

  5. Jumper wires


  1. Connect the LEDs to different digital pins on the Arduino, each with a current-limiting resistor.

  2. Write a code that emulates the traffic light sequence – red, red-yellow, green, yellow, repeat.

  3. Upload the code to your Arduino and observe the LEDs following the traffic light pattern.
