Snap Circuits Pro 500 uses building blocks with snaps to build the different electrical and electronic circuits in the projects. Each block has a function: there are switch blocks, lamp blocks, battery blocks, etc. These blocks are in different colors and have numbers on them so that you can easily identify them.

The circuit you will build is shown in color and numbers, identifying the blocks snapped together to form a circuit. Snap Circuits 500 contains over 75 parts so you can build over 500 exciting projects or create your own exciting experiments. An instructional manual is included with complete directions to build Projects #1- #511.
