In the video after the break [365 Robots] takes us through the build process of a closed-loop motor with a custom optical encoder ... stand with load cell and Arduino. Like other PCB motors ...

You can salvage some nice motors out of optical drives but they can be tricky to control. That’s because brushless DC motors require carefully timed signals used in a process called Electronic ...

An Arduino Pro Micro is a great choice because it connects easily via USB. Pair it with a high-quality optical sensor like the PMW 3389 for precise tracking.

The associated demonstration code continually streams increasing integer values through the Arduino UART to the transmitter, and receives them back via the fibre link. “To show this running, we put a ...
