This project is called a Wobble-Bot. At the end, the motor will allow this robot to wobble back and forth and move around. It can be turned on wan off with a simple push button switch.
Use the wire strippers to strip the wires connected to the battery pack.
Use a soldering iron to solder an end of one wire of the battery pack to one of the two ports of the motor. Solder the remaining wire from the battery pack to a wire from the switch. Then, solder the other wire from the switch to the remaining port of the motor, thus completing the circuit.
