The idea behind the project is simple: take a stepper motor, put a needle on it, and connect it to an Arduino. Instant analog gauge, measuring anything an Arduino can calculate.

Leveraging the Trinamic TMC2208 stepper motor driver gives Ethersweep silky smooth and quiet motor control, which could be very important for some applications.

This is the first part exploring the motor control shield that I designed for the project where I was doing 3D Printer Filament Measuring with Arduino. The DC motor portion of the project is based on ...
