555 Ohm Book

Periodically I have worked with the Northern Illinois University STEM Outreach program to teach young people about art and technology. In 2012 the DeKalb Public Library received a grant to run a class that would result in a permanent electronic sculpture to be housed at the library. After a basic introduction to electronics, the class (3rd-6th grades) were taught how to build a circuit using the 555 timer. With the 555 we made a solar-powered sound synthesizer and several types of LED lights.
