Tech post #5

2 weeks ago we started working on a project where we make circuits that all lead to a LED light bulb. There had to b e a switch on it so we can turn it on and off, for example you could put a concudctive piece of tin foil and wrapped it around a piece of cardboard. Then you wrap it around another piece beneath it and connect it to your circuit and press the peices of tin foil together lighting up the light bulb.
