Squishy IR-based Switch

To make this squishy button, you will need:

    - a squishy membrane (step 2 and 3 cover how to make this part)
- a custom PCB (step 4 and 5 cover how to make the PCB)
- IR emitter and detector pair
- 10Kohm resistor
- 82ohm resistor
- 22 AWG wire (preferably three colors)
- four #6 screws (length depends on your design, we use 10mm (0.39”))
- an Arduino (we use a Uno)
- screw driver that matches the four screws
- soldering iron

A few notes.

The soldering iron was late for the photoshoot, but you will still need one.

You will need the four screws to attach the squishy membrane and the PCB to the object you want to add the squishy button to. We use 10mm (0.39”) wood screws, which work well for our plastic prototype and the thickness of our button.

Go through the steps first as you may need some extra materials to make the squishy membrane and the PCB. We list a few options, some require more time, others require more handywork.
