The kit uses closed loop electrical signals (circuits) to send the computer a signal to make a sound or reaction. These sounds can be created through coding in Scratch or online computer generated sounds. Watch the video to the side to learn more. 

Need a reminder of how circuits work? Remember this:

• A complete path around which electricity can flow

• It must include a power source

• Materials such as metal that allow electric current to pass through them easily are called conductors.
