You can salvage some nice motors out of optical drives ... DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC). [Fileark] built and ESC using an ...

Unlike most other DC motor driver modules, this module has a single ... Even though it’s easy to use a microcontroller like Arduino to test the module, I simply rigged a circuit for that job. As you ...

To fix this, [MechanicalCat] has come up with a current limiter for cheap DC motor controllers. The full write-up is in the included PDF file, and describes the set-up of an Arduino Nano sitting ...

Never use this Circuit (right) There is a drive circuit that appears all over ... the positive rail can be any dc voltage – more or less that the Arduino, so great for 12V motors. And it is compatible ...

protection circuits, and sensing for voltage, temperature and current sense – both phase and leg shunt current sensing is supported. And the same board can be re-configured for multi-phase dc-dc ...
