Controlling Multiple LEDs Without Loops | Arduino Basics

In this video, we take full control of five LEDs using the Arduino UNO—without any loops! You’ll create a variable for each pin, use digitalWrite() to turn LEDs on and off in sequence, and start to recognize patterns in repetitive code. This sets the stage for using smarter solutions like for loops in the next lesson.

💡 What You’ll Learn:

How to control multiple LEDs using separate variables

How to write sequential LED commands without loops

Why repetitive code is a clue to optimize with smarter logic

How to use the Serial Monitor to follow what your code is doing

🛠 What You’ll Need:

Arduino UNO

5 LEDs (any color)

5 x 220Ω resistors

Breadboard and jumper wires
