Lesson: 10 - How to Use a Relay Module with Arduino | Complete Beginner’s Guide
Hello and Welcome to Electro Nerds Academy! In this video, we’ll learn how to control high-voltage and high-power devices like AC bulbs using an Arduino and a relay module. Since Arduino pins can only handle 5V DC at very low current, we use a relay as an electrically operated switch to safely control larger loads. What you’ll learn: What a ...
