Cheap and cheerful.

Abstract: This paper presents a precision capacitive rotary encoder that integrates a shared charge amplifier, and a multi-stage offset calibration scheme. Recently, capacitive encoders have gained ...

This project implements an encoder-based measurement system and PID control for motor speed using Arduino. It includes pulse reading, speed calculation, and closed-loop PID control with simulation ...

We've all heard that "if you want something done right, you have to do it yourself." And that’s usually fine when it comes to ...

MicroPython is a well-known and easy-to-use way to program microcontrollers in Python. If you’re using an Arduino Uno Q, ...

Write and test first, then buy the hardware you need.

If you were to point to a single device responsible for much of Hackaday’s early success, it might be the Arduino Uno. The ...

The Q2 sits in the same class as the BMW X2 and Mercedes GLA, but having launched back in 2017, the Audi is feeling its age compared to its relatively fresh rivals. In some areas that’s a good thing, ...
