Cheap and cheerful.

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 ...

Building Arduino projects with multiple sensors can unlock powerful environmental monitoring, automation, and IoT applications. From DHT11 temperature sensors to motion, gas, and light detectors, ...

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 ...

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

Is it something in the water, or have there been a lot of really cool servo projects lately? Mechaduino is a board that sits on a regular stepper motor and turns it into a servo with a closed loop ...

Electrical energy is no longer treated as an unlimited utility. Every watt consumed has a cost impact, an efficiency implication, and in many cases a safety consequence. A smart grid in IoT is not a ...

Measuring the speed of a rotating object is a common requirement. Knowing the speed of table and ceiling fans, as well as kitchen appliances such as mixers and grinders, can often be useful. However, ...
