Adafruit Capacitive Touch HAT for Raspberry Pi will inspire your next interactive project with 12 capacitive touch sensors. Capacitive touch sensing works by detecting when a person (or animal) has touched one of the sensor electrodes. Capacitive touch sensing can be used used for touch-reactive tablets and phones, as well as control panels for appliances, which is where you may have used it before. Adafruit Capacitive Touch HAT for Raspberry Pi allows you to create electronics that can react to human touch, with up to 12 individual sensors.
Adafruit Capacitive Touch HAT for Raspberry Pi has 12 'figure 8' holes in it that can be gripped onto with alligator clip cables. Attach one side of the clip to the HAT and the other side to something electrically conductive (like metal) or full of water (like vegetables or fruit!) Then start up Adafruit’s handy Python library code to detect when the object is touched.
Adafruit Capacitive Touch HAT for Raspberry Pi works great with Raspberry Pi Model A+, B+, or Pi 2. This HAT can be used with Model A or Model B but requires purchase/soldering of an extra-tall 2x13 header instead of the 2x20 included.
Note: A guide for using this HAT is work in process. Until it is complete you can look at the guide prepared for the stand-alone version of this HAT. The link is listed under “Documents” title.
