Grove Zero - Touchpad
Touchpads are an input module to turn conductive objects such as a banana or the human body into triggers to control your circuit.
Module Category: Input
What is it?
The Touchpads measures the ambient temperature, in Celsius degree (℃) and relative environmental humidity levels (%).
Grove Zero Series Introduction:
Grove Zero is a set of programmable elctronic building blocks which snap together with magentic connections & are used in conjuction with graphical programming software to achieve creative and functional projects. Grove Zero can be used boths as a tool to foster children's creativty as a classroom tool for STEM education. Learn more about the series here.
If this is your first experience with the Grove Zero series, we recommend that you purchase introductory kits such as the Starter Kit, Car Kit or Bit Kit, which include instructional documentation to help you get familiar with this educational series.

How this module works?
The module is composed of 4 touchpads labeled from 1-4. The metal contacts between the touch pad 1 and 2, 3 and 4 are GND (labeled as Earth on board) that we can see in most of the circuits.
Use your finger tip to touch both a touchpad and the GND pad beside it, or connect them up with an alligator clip or 4 mm banana plug, then the corresponding switch is turned on. When a touchpad is connected to GND, it completes a circuit and send closed loop electrical signals to trigger an event like button click or press. When a touchpad is connected to the GND, the LED indication light beside the touchpad will also light up.
You can program the Touchpad very easily with Codecraft to achieve more creative and challenging projects.
Connect modules together as shown below and touch one of the touchpads and GND at the same time, see what happens:
