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 rot… ...

Finally, the knob on the right could reasonably be thought to be a rotary encoder, but it’s actually connected to a small DC motor. By biasing the motor with a small DC voltage applied to one ...

This repository contains a project for controlling the speed of a DC motor using a PID controller implemented on an ESP32 microcontroller with micro-ROS integration. The ESP32 communicates in ...
