Datasheet

Using an Arduino Leonardo and a little bit of creativity you can use it to
turn touches into keyboard KeyUp/KeyDown presses or pair it with the
Music Maker shield to create an audio player that will play a sound per
sensor.
Each order comes with a Capacitive Touch Shield and a stick of 36-pin
headers. You'll need to do some light through-hole soldering to attach
the headers onto the shield circuit board.
Please note! This kit does not come with Arduino or alligator clips.
