This project uses two continuous servo motors, powered and controlled via a Circuit Playground Express.

The Vout pad on Circuit Playground Express (CPX) is connected to each servos' red wire, the A1 and A2 pads to the yellow wires, and the two GND pads to the servos' brown wire. 

The alligator clip-to-male jumper wire connectors are great for connecting servo motors to CPX.

Circuit Playground Express can use a variety of power sources, anywhere between 3V-5V is safe. These compact 400mAh lithium ion polymer batteries are excellent for powering small projects like this. 

A set of 3 AAA batteries also provides ample power, if that option is more convenient. If you're using a AAAx3 battery pack, check that the switch on the battery pack is set to "ON" when you want to power the boat.
