First littleBits RV Project


B decided she needed a doorbell outside her bunk, so today she got out her littleBits kit and got to work. She built a pretty cool circuit that allows a visitor (like a brother) to ring the doorbell if her privacy curtain is down. If she is available, she pushes a switch inside that causes the “come in” sign to light up. I was really impressed with her design because she used the “and” bit, and she also made a cover for the button to make it look more like a real doorbell!

Swing low, sweet voltage
