Step 5: Multimeter Test
To test the individual inputs, layer the circles as follows:
- TOP neoprene
- Squishy packing material
- VCC neoprene
- INPUTS neoprene
now you can either use a multimeter and check the inputs individually by connecting each input to the VCC in tern and when applying pressure to the top of the connected input you should get a change in voltage of a few hundred Ohm (the harder you press the less resistance).
If you have a constant connection or no connection at all then you have a problem. Check all your connections and make sure the ex-static is in place.
If everything is working. Great!
