Arduino AC Dimmer Using TRIAC & MOC3021 | AC Load Control | Dimmer Circuit Explained (Hindi)

In this video we will learn how to build an AC Dimmer using TRIAC, MOC3021 and Arduino Uno 🔌⚡. This project allows you to control AC power using Arduino which can be used for light dimming, fan speed control, and AC load control. We will understand the TRIAC control circuit, zero-cross detection, and how Arduino uses interrupts to control AC phase angle. Also we will write and understand the Arduino code step by step and test the module. If you are interested in Arduino power electronics projects, this tutorial will help you understand the complete working of an AC dimmer module. ⚠️ Warning: This project uses high voltage AC, so work carefully and follow proper safety precautions. ✨ Resources Mentioned: Full Source Code : https://drive.google.com/file/d/11uRr...
