Electronics

The circuit for this project is fairly simple, using only five main components including the Itsy Bitsy board. The Itsy Bitsy M0 is running CircuitPython code to control everything and to supply power and ground via USB or battery power. A LiPo backpack is soldered on top of the Itsy Bitsy to easily add-in a LiPo battery for power that can be charged via the Itsy Bitsy's USB port and to allow for a power switch.

A potentiometer with a built-in switch controls the rotation speed and can turn everything on or off. A SPDT switch controls whether the turntable spins clockwise or counterclockwise and of course, the star of the show, a servo motor, of the continuously rotating variety, receives its orders from the components while sporting a circular horn that will fit into its 3D printed part.
