The Arduino Opta micro programmable logic controller (PLC) provides a unique entry point into the automation field. Automation fields like smart homes, process controls, and robotics are project areas ...

Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. They exploit ...

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, ...

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 ...
