More info


The therapy Touch HAT will allow to create an interactive object using Arduino that can detect up to 12 capacitive touch sensors. The capacitive supports are going to detect when a person (or animal) touches one of the sensors connected to the electrodes.

The shield has 12 holes-shaped"8" to be able to connect easily with cables with crocodile clips. is easy to use, simply plug the cable crocodile on the shield on one side and to connect either to a driver object (for example, metal) or an object filled with water (as a result).

Then just work with an Arduino sketch to detect the support on the different objects that you touch. For experienced users who want to keep their permanent mount, it is possible to solder directly on the pads.

With a Arduino Leonardo, it so very simple to emulate a keyboard and create a plant keyboard!

The product is sold assembled and tested with:

  • 1 X Connector 1 X 36 point soldering to connect on the Arduino


  • Dimensions: 53mm x 68mm x 2mm / 2.1 "x 2.7" x 0.08 "
  • Documentation:

Use the MPR121 cable in I2C on SDA and SCL.
