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 ...

I made this project because I wanted a way to automatically control the speed of a DC fan according to the temperature read by a LM35 sensor. I had a few problems with the PWM part mainly because the ...

Electronic speed controller with arduino project illustrate a physical 3-phase motor driver system. It features high current MOSFETS, dual MOSFET drivers, and an arduino nano. A DIY motor driver board ...

If your memory of slot cars as a childhood toy is of lightweight controllers with wire-wound rheostats inside, then you’re many years behind the state of the art when it comes to competitive slot car ...

I have a friend (stop laughing -- it’s true -- I’m not going to proceed unless you get yourself under control -- thank you). We will call my friend Guido Bonelli (because that’s his name). Guido has ...

If you are interested in creating a DIY Arduino wind speed meter or anemometer to monitor the wind strength in your location, you might be interested in this quick tutorial I have put together to ...

Permanent magnet dc motors need a chunky inductor in series with them if they are fed from an SCR (thyristor) based mains power controller. It is (probably!) possible to safely interface an Arduino to ...

Is the Arduino Uno Q the missing piece in your next project? With its hybrid design that fuses the precision of a microcontroller with the flexibility of a Linux-based single-board computer, this ...
