Touch (knock) sensor with Piezo

If you want to make a simple touch sensor but you don't have the fancy ones around you can also use a piezo element, which come with a lot of basic arduino starter sets.

What you need:

piezo element

breadboard
 

resistor 1 M ohm


piece of paper tape

some male/male jumper wires

This video explains it all. To make the input visual, open the serial Monitor from the Tools menu.
