Add a cool touch interface with your project with this microcontroller-friendly touch-pad. This PS/2 track-pad that is easy to use and interface with. 

This track-pad is two-in-one: you can use it either in relative 'mouse mode', where it spit out finger movements as they change OR you can put it into 'tablet mode', where it give the absolute X and Y location of the point being touched. It will also return Z coordinates for how hard the user is pressing and a flag if a finger is touching the pad or if the finger was removed (so you know its no longer being touched). 

This device does not support multitouch, but it does have basic gesture support for 'tap' and 'double tap' on the touch-pad area. There's also two tactile buttons that act like a the two buttons on a mouse. 

We thought this would make a great interface, such as for a lighting controller, music devices, or for drawing shapes. You can easily connect these to arduino , simply use our PS/2 breakout cable to any 2 digital pins and run code below.
