For this project, we made a mechanism that flips a light switch on and off using a servo module.
This servo mechanism is connected to a wireless receiver module and is activated by a pressure sensor on a wireless transmitter circuit.
Automate your lights and make a handheld remote control with littleBits, or for all you pranksters out there, place the transmitter circuit in an unsuspecting place and trick your friends, like we did. We placed the pressure sensor on the transmitting circuit under the leg of a chair. When someone sits on the chair, the overhead lights will go off. When s/he gets up to turn the lights back on, the lights turn on again on their own… and so on. Sit back and watch hilarity ensue. To see our prank, check out this video!!!
