This is an easy tutorial showing how you can control the brightness of an LED or adjust the speed of a DC fan using Arduino Board, a small BC547 transistor and a potentiometer. In my example the whole ...

Driving a brushless DC (gimbal) motor can be a pain in the transistors. [Ignas] has written up a nice article not only explaining how to do just this with an Arduino, but also explaining a little b… ...

That’s because brushless DC motors require carefully timed signals used in a process called Electronic Speed Control (ESC).

The Pi compatible DC Crank Set allows you to charge devices or simply communicate with your Arduino or Raspberry Pi mini PC. Watch the demonstration video below to learn more about the latest ...

This paper presents a DC motor speed controlling technique under varying load condition. The linear system model of separately excited DC motor with Torque-variation is designed using PID controller.

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 ...
