When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...

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 ...

[Jean-Noel] is fixing a broken Lurem woodworking machine. This machine uses a three-phase Dahlander motor, which has three operation modes: stop, half speed, and full speed. The motor uses a special ...

Brushless motors are ubiquitous in RC applications and robotics, but are usually driven with low-cost motor controllers that have to be controlled with RC-style PWM signals and don’t allow for much ...

DGD2136 is a 600V integrated three-phase gate driver IC from Diodes, intended to drive six n‑channel mosfets or IGBTs in three half-bridges. While inputs that work down to 2.4V allow it to be ...

Arduino enthusiasts may be interested in a new piece of Arduino motor Shield created by Richard Willmott based in the UK, which launched this week via Kickstarter with the aim of raising the £5,000 ...
