Last time, we went through the basics of how to make simple electrical circuits with play dough and light-emitting diodes, now it's time to experiment with electricity. By Ruben Meerman.

When looking for things to write about, there is nothing we like to see more than well-documented schematics and code available for download. In the case of schematics, we realize that they can be … ...
