Cost: $9.95 each
Description: This is a 4-wire analog touch screen originally designed for the Nintendo DS. Add this touch screen to any LCD you want! 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.
