I’m making a dance floor for my kids and thought that it would be fun to add some pressure sensors in the floor to flash some lights, etc… So I did some research and found that using velostat hooked up to an analog pin might work for it. I was trying to figure out the best way to do it, but I’m having trouble figuring out how to get accurate measurements of the resistance. The numbers seem to jump around quite a bit and never seem to settle, I’m confused by what I’m seeing.
Anyone have insight into what I’m seeing? or any suggestions how how to better measure it? or anything I can add to the circuit to make things clearer?
I’ve uploaded a video showing what’s happening. I would appreciate any help or suggestions anyone has.
