Digital dimmer using Microcontroller atmega8

This project is used to control the brightness of the lamp or can be used to control the speed of the fan. The system consists of 3 block they are Zero crossing detector Microcontroller (Atmega8) Load Driver (BT136)As the name implies the zero crossing detector generates pulses for every zero crossing of the input AC signal. This pulses are fed to the microcontroller interrupt pin through the opto coupler. ...
