using touch pads instead of conventional push buttons in electronic voting machines

I need to interface Touch pads with microcontroller in electronic voting machine projec...Plz can anybody help????

@ jabtin
touch pad or key pad
normal touch pad are same as keypad
but touch screen are different thing

@majoka
thnx for the reply....is interfacing normal touch pad same as interfacing a keypad...i mean the pin and programming logic

@ jabtin
yes coding is same just see with multimeter that which is column and which is row
nothing else needed

if your microcontroller doesn't have specialized hardware for capacitive touch sensing you have ways to do this
you can read about it here:
http://www.electronics-base.com/index.php/general-description/measurement/91-methods-for-capacity-reading-using-microcontroller
but i would recommend you to use dedicated hardware such as Microchip microcontrollers with mTouch CSM module inside
I wrote about this module in this topic:
http://www.8051projects.net/forum-t54220.html
and at the bottom of topic you have link to Complete project C code that is explained in details. I think this would help you to easily make your project
good luck

if i understood your question right :9
You asked for touch pad which would be capacitive sensing pad

@ jabtin
normally capacitive pads are capacitive
