Step 5Wrapping the Pads - Complete Sensor
Cut a piece of sponge that is slightly larger (5-10mm) on each edge and a little more than 2x longer than the size of an individual pad.
Place the pad loosely on the sponge.
Fold the sponge over and tape the 3 open edges.
You have a complete sensor.
---
If you want, you can test the responsiveness of the pads with an Arduino.
The pads work quite well.
