Capacitive Touch HAT for Raspberry Pi

Description

Shield for Raspberry Pi (A+ / B+ / 2 / 3B / 3B+) based on the MPR121 chip, providing 12 capacitive touch sensors for interactive applications. By programming the Raspberry Pi appropriately and attaching electrodes to something electrically conductive (like metal) or containing water (like vegetables, fruit, or a container of water), when a person (or animal) touches the object, you can make it play a sound or do something else. Applications are numerous, from a piano to a complex musical setup, from interactive control panels for appliances, etc. Dimensions (mm): 57x65x3, weight: 10 grams.

Note: Raspberry Pi and crocodile clip cables are not included.
