You can now very easily add touch and gesture control to your electronic projects! How? With Hover!

Hover is a development kit that lets you control your Arduino projects in a whole new way.  Wave goodbye to physical buttons.  Hover detects hand movements in the air for touch-less interaction.  It also features five touch-sensitive regions for even more options.

The little capacitive touch sensitive PCB fits a standard breadboard. The gesture detection range is up to 5 inches / 13 cm and it needs a 3.3V power supply. For $39 you can order it here.
