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 ...

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 ...

A sophisticated fan control system built with Arduino that provides precise temperature control through either PID control or custom fan curves. This project is perfect for cooling applications where ...

Must admit I'm not up to speed with Matter, a way to standardise IoT elements. So it's welcome to see a basic introductory tutorial on using the wireless protocol on the Arduino website. With ...
