## Description

The Adafruit Capacitive Touch HAT adds 12 capacitive touch sensors to your Raspberry Pi using the MPR121 touch controller over I2C. Each sensor has a figure-8 hole designed for alligator clip connections — attach clips to the HAT and the other end to anything conductive (metal, fruit, vegetables, or water-filled objects) to create touch-reactive projects. The included Python library makes it straightforward to detect touches, convert them into keyboard keypresses, or trigger audio playback. No soldering is needed for the touch connections themselves — just clip and go. For permanent installations, solder pads are also available. Key Features 12 Capacitive Touch Sensors – MPR121 controller with I2C interface Figure-8 Alligator Clip Holes – Easy grip connections for each sensor pad Python Library – Detect touches, generate keypresses, or play audio per sensor HAT Form Factor – Plugs directly onto the Raspberry Pi 40-pin GPIO header Solder Pads – Available for permanent, slimmer connections Compatibility Raspberry Pi Model A+, B+, Pi 2, Pi 3, Pi 4 (with included 2×20 header) Raspberry Pi Model A or B (requires a 2×13 extra-tall header, not included) Ideal For Interactive touch installations Fruit and vegetable keyboards/drums Touch-activated audio players Educational projects and exhibits Important: This kit does not include a Raspberry Pi, alligator clips, speaker, or fruit.
