This LED DIMMER is an Arduino Uno based PWM (Pulse Width Modulation) circuit developed to get variable voltage over constant voltage. The method of PWM is explained below. Before we get start building ...

In our household, most of the appliances are powered from the AC supply such as Lights, TVs, and Fans, etc. We can turn ON/OFF them digitally if needed, using Arduino and Relays by building a Home ...

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 ...

This project is a simple LED dimmer circuit that uses Arduino's PWM (Pulse Width Modulation) capability. The user can smoothly adjust the brightness of an LED using a potentiometer or digital input.

AC loads are everywhere around us because at least home appliances are supplied with the mains power. Therefore, we always face the situations that we want to have full control (dimming) over an AC ...

Abstract: Direct AC LED drivers have advantages over conventional LED drivers in size and cost because of no need for bulky and expensive inductive components. However, none of conventional direct AC ...

Abstract: In this paper, a dimmable ac LED driving circuit with high power factor and low total harmonic distortion is presented, which takes series driving via the basic unit mainly constructed by ...
