Touch screens normally have a small PLC inside. You can use that for controlling relays if your logic is simple.

Thankyou for your reply

Can you please provide some technical information on how to do it?

My logic is extremely simple but i dont know how to start. I will have to develop a GUI which means i have to write a software too which in turn means that i have to have a processor too. I am confused where to start.....

hi, a touch screen device consist of 2 section namely a touch screen and driver circuit. the touch screen will be connected to the driver circuit. the driver circuit can be connected to the micro controller through serial communication. when a touch is sensed by the touch screen the driver will transfer its coordinates value serially, which can be gathered by the micro controller and can identify in which place the screen as been touched and further action can be taken.
