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 ... easy to use a microcontroller like ...

A friend asked me if I could develop a low-cost power driver for toy/hobby DC motors so he could use it with ... think that the motor driver only needs to support the nominal rated continuous current.

In pushing these little electric vehicles to the limits, many builders use ... cheap DC motor controllers. The full write-up is in the included PDF file, and describes the set-up of an Arduino ...

UPDATE: There are some cheap motor driver boards for Arduino projects at the end of this blog. Never use this Circuit (right ... the positive rail can be any dc voltage – more or less that the Arduino ...
