There's loads i haven't done with the sensors i got during #mayke though, and do feel more confidence to experiment now! This is a chonky HR-SR04 ultrasound distance sensor, range meant to be 4m but it's more like 1.4m (tested by making the kid back slowly away)

This video probably doesn't make much sense, the ceiling's too far away to detect, the light gets brighter as you approach within range. You can sort of feel the shape of the ultrasound wave with your hands
