Thank you to PCBWay for sponsoring this video, get yours here: https://www.pcbway.com/project/shareproject/Motion_Sensing_Light_6c1b90fe.html I designed a PCB to solve a problem I have been having - I have to walk across a dark basement to turn on my studio lights. This pcb will provide me with literal hours of light and I don't even need access to any wires!
