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. The motor used in ...

The solution is named Ethersweep, and is a small PCB stack that sits on the rear of the common NEMA17-format stepper motor ... with the Arduino software stack deployed, making uploading firmware ...

We’re not going to walk you through every step ... you’ll learn how to connect LEDs, buttons, resistors, potentiometers, and servos to either a power source or Arduino. With just those ...
