We made a tickle machine using the LittleBits which is a set with lots of electronic parts that can make an amazing circuit.
We made the tickle machine by using a 9 volt battery which had a cord that attaches to where the circuit starts. There was also an extension cord that then attaches to a motor with a motor mate that we attached onto ourself. Then we would use masking tape and stick a feather onto the motor mate. At the end we would flick on the switch which was at the start of the circuit that would turn on a red light and start the circuit.
The motor was rather slow but I think that it was great fun using the LittleBits and making the tickle machine from all the electric components.
