The Arduino has been used for many purposes, and “shields” are available to make many common tasks easier. However, [Nick] wanted a stackable motor driver shield, so he build one himself!. There are ...

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 ...

The table shows the pin configuration of the Arduino UNO–based robotic arm. The red (VCC) wires of all servos are connected ...

I have been trying Fritzing, the free schematic capture and pcb layout tool, which also does breadboard layouts too. It is good? The short answer is excellent – particularly as it seems to be the work ...

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 ...

Recently, I found an interesting fan motor module in a web shop and grabbed a couple of them for nothing. At the heart of the module is an eight-pin L9110 DC motor control chip from ASIC (www.asic.net ...
