Dance dance Re-Volt-Ultron
In this project we got to make dance pads, out of card board and tin foil. Once you step on one of the pads, a light bulb turns on, when you take your foot off it turns off. David, Ellie, and I made this in under 3 weeks.
How they work.
A simple circuit just needs positive and negative charge from a battery, so if you touch a bulb with one side of the battery and connect the other side of the battery and the bulb with a wire it will turn on. If you need wire and you don't have any you can just use a conductor. A conductor is usually metallic, it works just like a wire, it lets electric charge pass through it and out to the other side. If it's not doing that its probably an insulator, that is something non metallic that electric current cannot pass through.
