# Motion-activated USB power passthrough

This project includes all parts to build a motion-activated USB power passthrough device, including circuit design, code, and a 3D model to house it all.

Our use case was to have stars light up whenever my son walked into his room, like so:

Power input and output are both 5V (in the example above, micro-usb from a phone charger and usb-a powered lights, respectively.)
