A couple of weeks ago, Room two made a prank handshake using the LittleBits. The LittleBits are lots of electrical components that have magnets on each end of them so they can attach to other electrical parts.
We made the Prank Handshake using a 9 volt battery, 2 extension wires and a button. First we attached the battery to cable that then attached to the main power board. We then attached the extension wire to a buzzer, then to another extension wire. After that we attached it to the button. We used rubber bands to strap them to our arm with the button on our hand and when you push the button the buzzer starts to ring.
