The circuit for this project connects two motors, one DC and one servo, to the Circuit Playground Express board using alligator clips.
The DC motor will begin running as soon as power to the board is turned on. This motor can be connected to either the Vout or the 3.3V pads on CPX board.
Power Options
Circuit Playground Express can use a variety of power sources, anywhere between 3V-5V is safe. This compact 2000mAh lithium ion battery is excellent for powering projects like this.
