Capacitive Touch Kit for Arduino

The Capacitive Touch Kit for Arduino provides responsive touch-based control options for your electronics projects. Powered by an MPR121 touch controller, this modular kit is ideal for students, makers, and hobbyists designing custom interactive interfaces.

Three distinct sensor pad types

The kit includes an iPod-style scroll wheel, a keypad that supports backlighting, and a grid touch pad. These interchangeable inputs allow you to experiment with various interactive control schemes.

MPR121 capacitive sensing technology

Driven by the MPR121 dedicated touch chip, the system provides high sensitivity and dependable touch detection. It accurately registers contact across all connected sensor pads.

5V Arduino board compatibility

The system operates at 5V and is designed for seamless use with Arduino boards, including the Arduino Uno and Genuino Uno. This standard operating voltage simplifies wiring and integration into existing prototyping workflows.

Complete modular hardware package

Each pack includes one control unit, one wheel pad, one keypad, one grid pad, and connecting cables. Everything needed to connect the capacitive pads to your controller is supplied in the box.
