Controls power in AC load through a TRIAC, performing AC phase cutting with help of a zero-cross detection circuit in a dimmer module. The module used was a RobotDyn AC Dimmer module paired with an ...

In this tutorial we will learn about an AC lamp dimmer using Arduino and TRIAC. Here a TRIAC is used to switch the AC lamp, as this is a Power electronic fast switching device which is the best suited ...

AC-Light-Dimmer-Module-with-ZC-Detector Controlling an AC load with an Arduino is simple using either a mechanical relay or a solid-state relay with an optically isolated triac. But dimming an AC lamp ...

Now it’s the time to connect the circuit to an Arduino board and control the AC load. I selected an Arduino Nano which introduces enough resources for this project, but you can use other boards as ...

The compact ac light dimmer module with zero-crossing detector described here is ideal for microcontroller-based ac voltage controlling applications and projects.
