Touch screen (Nintendo DSL digitizer)

A 4-wire resistive touch screen digitiser (originally designed for the Nintendo DS Lite) that works with a stylus or fingertip. It can be used with any microcontroller that has 2 digital pins and 2 analogue input pins, making it easy to add touch input to your projects — either as a standalone touch panel over a paper overlay, or attached to an LCD for a DIY touch display.
