« A Touchpad using Plastic and Aluminum Foil

The easiest, cheapest and fastest way in which we could implement a touchpad was to use simple metal strips horizontally and vertically. When the user touches, the two strips come in contact and this is detected by a micro controller. This data is then sent to the computer.
