The device is simple to use: just simply connect the PWM capable fans to the board, and power it using a 12 V DC power supply. The device uses an LCD screen to show information. The LCD screen turns ...

A small script that allows Arduino to separately set the speed of two standard CPU fans. In order to control those fans the Arduino needs to generate a PWM signal at 25 kHz frequency. This is ...

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 ...

The creative adventures with ATtiny series microcontroller are awesome if you know how to play them. ATtinys — especially the ATtiny85s — are all around us, and by using one, we can shrink the size of ...
