Introduce your students to simple circuitry with a kit designed to take the frustration out of electronics. Create a musical doorbell, alarm, clap sounds, police siren, blinking lights, flickering lights, and many more fun electronic devices—even electronic games! All parts are mounted on plastic modules and easily snap together, no further hardware or building is required. Just follow the color-coded diagrams in the instruction manual, clip the pieces together, then watch and hear the results! Kit contains 30 parts and an illustrated instruction manual with 101 projects. This Jr.-sized kit is the same as the original kit, but smaller with simpler concepts.
