Learn how to build a Arduino Opta DC motor controller with a pushbutton switch and a programmable human machine interface (HMI).

The controller in question is a 4QD Porter 10 so an extra component is a DC-to-DC converter to provide a floating ground for the Arduino.

Watch the demonstration video below to learn more about the LittleArm Big Arduino robot arm which has been specifically created to provide a desktop robotic arm construction kit perfect for both ...

If you've messed with Arduino, the inexpensive micro controller, you'll know that you can run a small motor or turn an LED on and off, but anything else - powering a pump, turning on a light bulb ...

Does it just stay there and do random things? Nope, of course not! [Guido] built it with a unique control box, two Arduino 2560’s and an Xbee to communicate between them.

Seeing this Toshiba motor drive, my first thought was ‘what a neat chip for pairing with an Arduino’ as it combines operation across 1.8 to 7V with up to 4A drive – so that is Li-ion batteries, 5V USB ...

It is a Clarke DCM10, a variant of Sieg’s X1, sometimes knows as a ‘micro mill’. Mine has a ~230V 150W brushed dc motor that needs driving from 240Vac mains power. Almost randomly, I settled on a ...
