You can create a direct servo motor controller with rotary encoder input, saved positions, and animation features. It's all coded in CircuitPython and runs on minimal hardware -- an ESP32-S2 Reverse TFT Feather, two rotary encoders, and batteries all mounted on a perma proto board. Easily swap in different servos and use the display to get all the relevant motor angle details. Become the boss of your servos!
