Touch Screen

Overview
This resistive touch screen can be used with a stylus or fingertip and is easy to use with a microcontroller. You can put it over a paper overlay for a touch control panel or attach it to an LCD to DIY a touch-activated display. Readings are taken by putting 5V across two of the pins and doing an analog to digital conversion on the other two pins. Full X and Y position can be achieved with only 4 GPIOs.
