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 ...

This is the first part exploring the motor control shield that I designed for the project where I was doing 3D Printer Filament Measuring with Arduino. The DC motor portion of the project is based on ...

Brushless DC (BLDC) motors are standard fare in low-precision, speedy RC applications. The control schemes needed to run them slowly or precisely go deep into motor theory and might put these motors ...

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 ...

In this article we will discuss how to build a powerful DC motor driver that can be controlled using a microcontroller like an Arduino or a Raspberry Pi, or even a standalone PWM generator chip. DC ...

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 ...

Sophisticated motor control is no longer the sole province of custom hardware and proprietary control techniques. Advances in powerful, low-cost digital-signal controllers (DSCs) let designers use ...
