Introduction

Now, it is time to add a more fancy interactive way to your project. This DFRobot touch kit comes with three types touch sensors. An ipod styple wheel touch, a keypad touch which supports backlit and a grid touch pad which can recoginze something unique. This kit utilizes the not very "latest" capactive touch technology which make the sensing very sensitive. The kit is designed to be compatible with Arduino.
