In this application we are developing a electronic equipment for AC Motor Speed Control Using Power Triac With Display Unit. Using this application it will be easy to control Speed of AC Motor switches. In this project we use array of switches for controlling motors. Each switch has its own functionality for controlling motors at different speeds. By using these switches variations of motor speed can be managed.

Basically AC motors need more current which is not provided by micro controller used in this project. So we use TRIAC driver for our driving AC Motor. Here we need to consider two factors , Firstly driving AC motor with low current and protecting micro controller from high current. In order to solve this problem here we are using MOC 3021. A 16X2 LCD for displaying the running motor speed.
