For the DDR Project we had to create a working dance pad that lights up or buzzes. The materials needed for the project were cardboard, wire, foil or conductive materials, batteries and a bulb. Everyone was put into groups. For example, I was paired up with Toby, Makenna and Katrina. We first made a working DDR pad with toilet paper rolls, wire, foil, bulbs, AA batteries and cardboard as a prototype. Then we made it so that it was safer to step on, than with toilet paper rolls so we replaced it with springs and duplicated it to make 4 working ones.
A simple circuit works by making a loop of electricity with wires, batteries and a bulb or a receiver. It could either be open or closed depending on how you make it. To make a simple circuit with a switch you leave the circuit open meaning that the electricity doesn't flow then close the circuit with a conductor to turn on the receiver. A conductor is a object that can conduct electricity, for example a penny is a conductor because it is metal. An insulator is an object that does not conduct electricity and stops the flow as well like a rubber ball. For our DDR pads we use spring, wire, foil, a bulb and battery. First we connect the batteries and wire to the bulb at the top of the pad. Then we connect one end of the battery to the bottom of the pad with wire. Then put spring and foil on the top to secure the safety of keeping the bulb in tact as well as making the top and bottom of the pad conductive. Last we step on the pad and make sure the bulb lights up and then duplicate the pad afterwards.
