Notify me when its in stockThis touchscreen HAT add-on for Raspberry Pi comes with 12 capacitive touch sensors that will inspire your next interactive project. Capacitive touch sensing works by detecting when a person (or animal) touches one of the sensor electrodes. Capacitive touch sensing is used in many devices like touch-sensitive tablets and phones, as well as control panels for various gadgets. This HAT allows you to create electronics that can respond to human touch with up to 12 separate sensors.
The HAT features 12 'figure-8' holes that can be gripped with alligator clip cables. Attach one side of the clip to the HAT and the other to something electrically conductive (like metal) or filled with water (like fruits or vegetables). Then start our handy Python library code to detect touches. It's that easy! For advanced users, you can also solder to a pad to create a slimmer and more permanent connection.
It works great with any Raspberry Pi that has a 2x20 connector. It can be used with Model A or Model B, but requires some extra effort to connect the HAT to the 2x20 connector (as opposed to the included 2x20 connector).
Check out the MPR121 sensor guide for CircuitPython and Python usage. Read touches, turn touches into KeyUp/KeyDown keyboard press inputs (so you can make a fruit-keyboard), and also play a sound for each sensor touch (fruit drums!)
Each order comes with a Capacitive Touch HAT and a 2x20 socket header. You'll need to do some light soldering to attach the headers onto the HAT printed circuit board, but it's easy to do with basic soldering tools like a soldering iron and rosin core electronics solder. You'll also probably want to get some 12-pack alligator clips!
You can order the Adafruit Capacitive Touch HAT - Mini Kit for Raspberry Pi from the Adafruit category at SAMM Market at an affordable price with same-day shipping and fast delivery.
