In this project we will demonstrate Arduino AC fan speed control using TRIAC. Here phase controlling method of the AC signal is used to control the AC fan speed, using PWM signals generated by Arduino ...

Circuit Diagram for the AC Fan Regulator The AC fan regulator circuit diagram is given below. The 220V AC mains voltage is given as the input to the one terminal of the fan (load) and the other ...

Here is a circuit through which the speed of a fan can be linearly controlled automatically, depending on the room temperature. This temperature controlled fan circuit is highly efficient as it uses ...
