Here is a motor speed sensor module, the major goal is to check the rate of an electric motor. The module can be used in association with a microcontroller for motor speed detection, pulse count, ...

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 Speed ...

This article will help you build a simple Arduino-based DCC system. Growing up in the 1980s I was living the dream. I had an ...

Note: This specialization requires purchase of a hardware kit in order to apply your knowledge and skill with real world tools. The hardware will be used to complete the lab exercises across the four ...

I was planning to use the opto-coupler speed sensor as part of a motor speed control – making the motor into the VCO block in a phase-locked loop. When this technique works, using it is simple: put ...
