This is yet another project born of necessity. It’s a simple circuit, but does exactly what it’s designed to do – dim LED lights or control the speed of 12V DC motors. The circuit uses PWM to regulate ...

Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. Here are two simple 12V DC motor speed controllers that can be built for just a few dollars. They exploit ...

Using three 12V DC motors, driven by MD10C-R3 controller boards, and controlled by an Arduino micro-controller, maker and YouTuber Ty Palowski has created an awesome t-shirt folding machine to help ...

You probably know that if you spin a motor (mechanically) it generates electricity on what would normally be the inputs. This can be a problem when you shut off a spinning motor and is the reason that ...
