E Blox Circuit Blox
Building circuits could hardly be easier! E blox uses Duplo®-sized building blocks as the unit size for their Circuit Builder series. Besides the battery holder, which uses 3 AA batteries (not included), sets come with a variety of switches, connectors, lights, sensors, buzzers, speakers, and motors. The clear base plate provides a solid foundation for all the circuits. Project book includes clear illustrations and written directions for building each project. Components are all numbered and colored for easy identification and proper orientation. A nice feature of the battery holder is the option to run a circuit on 1.5, 3, or 4.5 volts, depending on the connection point. Let 'em loose and see what they create!
