I am using PIC16F1936 and want to control the speed of an AC single phase motor using the switch interfaced to a PIC via PORTA.
I have implemented a circuit for controlling the speed of an AC Single phase motor using the switch interfaced to a micro-controller where each of the four switch allows the PIC to create a delay which is referred to as a firing angle.
Here below is the circuit with the code I tested and found that they are ok as with simulation in proteus it is giving correct firing angles.Unfortunately physical implementation is not working at all.
