Thats awesome! I have a related system for pausing music, but never thought of using an ultrasonic sensor. I might need to add that in! https://news.ycombinato

- stevekemp 9y agoI have something similar, linked above. If you're in a cube I wonder if you'd be better suited to an IR-beam break? If you have to walk through an "entrance" you could detect that happening pretty easily - although you'd want to avoid flaps to handle the case of somebody leaving too.
