The circuit for this bot requires connecting a servo motor and a DC motor to CRICKIT, the all-in-one motor controller that pairs with the best microcontroller anywhere: the Adafruit Circuit Playground Express.
A standard size plastic drinking cup fits almost perfectly over the CRICKIT. We will be using this cup as a housing for the electronics as well as a form upon which to build.
Here is a diagram showing the wiring for the motor, servo and Crickit
Connect the DC motor
Bend pins on DC motor. This will allow the cable to fit comfortably inside the rim of the cup.
Plug into motor terminals.
Use screwdriver to tighten down connections.
