'Tis the season for festive displays, but Hanukkah doesn't always get the same kitschy, fun decor that other holidays do. In this project, you'll build a planetary gear that rotates three dreidels using an STSPIN220 silent stepper motor driver and a KB2040 running CircuitPython. It's giving Stu Pickles chaotic menorah energy from A Rugrats Chanukah Special.
An MPM3610 buck converter makes it possible to power the entire project with a 12V power supply. The stepper motor needs 12V and then the MPM3610 is able to output 5V to power the KB2040 via its RAW pin.
