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 relay is and how it works ⚡ ✅ Relay schematic symbols and types (SPDT, SPST, DPDT) ✅ Relay module circuit diagram explained ✅ Relay specifications and markings (coil voltage, contact ratings, datasheets) ✅Step-by-step project: controlling an AC bulb with Arduino using serial monitor commands ⚠️ Safety Note: We’ll be working with mains AC voltage, so please be careful when replicating this project. And we are not responsible for any harm caused.
