What do you use your touchpad for? Moving a mouse around on your computer screen? Well now there is a cool new use for your typical computer touchpad, Dave from Plastibots has made a Dual LED Desk Light Controller that uses it for lighting control.

“Relative mode is the norm.  It works like you would expect it to on a laptop.  No matter where you put your finger and move it, your mouse will move from its current point in the direction you move your finger.   Well, I’m not using a computer or moving a mouse around.  I needed the unit to work in absolute mode.  I need to know the exact X/Y coordinates of where my fingers were moving. Knowing this, I could create mapped areas to monitor in the Sketch and perform various actions when movement was detected in those areas. “
