Windmill

Fully automatic moving windmill-shaped decoration. It is powered by 12V. 

The motion mechanism consists of a NEMA17 stepper motor. 

The electronics include an Arduino Uno,  CNC shield, and a TMC 2208/20029/2225/2226 stepper driver. 

The windmill features 12V 5mm LED backlighting that can be turned on or off separately as needed.

 I recommend wiring it according to the included schematic. The stepper motor ensures completely silent operation, which is very important for indoor use. I also have a version with a 12V / 7 RPM DC motor, but while this setup is easy to put together, its noise level makes it more suitable for the garden.

I can easily create an AI script for Arduino, or I can attach my script upon request in the comments.
