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 ...

If you want to add brightness control, you need to either buy a dimmer module, or roll your own. [PatH] from WhiskeyTangoHotel choose the latter route, and built a super simple LED controller for ...

Arduino simulator window. The Arduino Sketch (code) is simple and flexible. The Delay at the end of the Loop procedure is added deliberately to avoid possible switching errors. The delay of 250ms woks ...

Figure-5, The PCB layout of the AC dimmer. All components are Dip. Therefore it is easy for everyone to solder the components quickly and use the circuit as a module. R2, R4, R5, and R7 are 1W ...
