Multiple Blinking LED on Arduino
In this video, you’ll learn how to blink multiple LEDs on Arduino using millis() without using delay(). The LEDs blink one after another, with only one LED ON at a time, making this example perfect for beginners who want to understand non-blocking Arduino programming.

We use a simple array-based state machine, where the array index acts as the state. This makes the program dynamic and scalable—you can add or remove LEDs easily, and the code will automatically adjust. The example is demonstrated using the Arduino Mega (ATmega 2560 R3).
✨ What you will learn:
🔴 How to blink multiple LEDs on Arduino
🔴 Why millis() is better than delay() for real projects
🔴 How to use arrays for LED control
🔴 Common wiring mistakes and troubleshooting tips
This tutorial is ideal for students, hobbyists, and beginners getting started with Arduino projects.
