We always think it is interesting that a regular DC motor and a generator are about the same thing. Sure, each is optimized for its purpose, but inefficiencies aside, you can use electricity to rotate ...
This repository contains my Arduino Nano project for controlling a DC motor using an L298N motor driver, measuring real RPM with a quadrature encoder, and displaying the motor status on an SSD1306 ...
Connect Raspberry Pi/Arduino, motor driver, and encoder grounds together. Power motors from the appropriate external supply—not the Arduino 5 V pin. A 5–24 V encoder must provide a 5 V logic-safe ...
