The circuit accepts input DC voltage from 3 V to 12 V to control DC motors (3 to 12 V) linked to the L9110 dual-motor driver module. The prototype was tested with a 5-V/1-A DC power supply and 5-V/350 ...

So long as the 0V rail is connected to the Arduino 0V rail, the positive rail can be any dc voltage – more or less that the Arduino, so great for 12V motors. And it is compatible with both 5V and 3V ...

A friend asked me if I could develop a low-cost power driver for toy/hobby DC motors so he could use it with his microcontroller-based small electronics toy projects. Challenge accepted, the concept ...
