The DC (or "Direct Current") motor rotates a shaft when you send it an ON signal. It even has a switch to set the direction of rotation! It also includes the motorMate-- an accessory that makes it easy to attach wheels, paper, cardboard, and lots of other materials to the motor. Simply slide it on the "D" shape on the shaft. Try attaching various things to make windmills, cars, helicopters and more.Check out our Tips + Tricks for more ideas on using the DC motor!
