In this video, we will understand how the dimmer from Robotdyn works, designed to manage the load in AC grid using a microcontroller on the Arduino platform. With this dimmer, you can adjust the brightness of incandescent lamps and dimmable LED lamps. You can also control the engine speed or heater power (heating element, nichrome spiral, carbon thread). The basis of this dimmer is a BTA16600 Symistor, which allows you to control the load with a current to 16a. On the module board, the optoparas are Installed, which exclude the contact of the arduino conclusions with the AC 220V grid.
