In this insightful and educational video, learn how to make a mini generator 220v using a DC motor. This step-by-step guide ...

This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an ...

A teacher I know is stuck, with only npn transistors in the supply cupboard and the need to create a reversible motor drive for an Arduino project. Reversing ‘bridges’ have four switches (relay ...

RuggedCircuits.com is a website that offers custom circuits designs. Their product includes Ruggeduino – a ruggedized Arduino-compatible microcontroller board; Rugged Motor Driver – a motor driver for ...

The circuit in this Idea for Design provides three levels of speed control for a dc motor using a PC’s parallel port (LPT1). A C++ program performs the control functions by allowing the signals from ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

Running a brushed motor in muddy or dusty environments takes a toll on controllers, with both heavy back EMF and high stall currents. This explains one of the challenge in Europe’s Hacky Racer series, ...
