Touch pad testing

I began prototyping different types of pressure sensors, with different materials to see which would react the best. This is a video showing the first prototype, made from two layers of perspex held together with a wooden frame and a piezo sensor between them. The test circuit is a simple one using two LED’s, one green and one yellow. The idea is when the pad is tapped lightly, the green LED will flash and when a heavier touch is used, the yellow LED will light.
