DIY Breathing Strap

Note: This is basically a placeholder for a future breakdown. It still has some resources for you to dive into in order to construct your own but it's not a step by step write up.

Breathing Strap

The basic premise is using a conductive rubber cord that shifts in resistance when it is stretched and retracted. We cut a small piece, attach both ends to a belt and an arduino and we can then monitor the shifts in resistance to feed breathing data to a future Unity program.
