This Mystery Dreidel has a Circuit Playground Express (CPX) inside to add even more suspense! The sides are unmarked, so you won’t know what letters are spinning by until it stops. Then the accelerometer built into the CPX microcontroller board senses which way it’s pointing, plays appropriate music, and flashes lights through the cut-out letters on the sides to show which face is up. To make it extra festive, when you first turn it on, the CPX plays the chorus of the Dreidel Song. (You can make it play again by turning the dreidel upside down.)
