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 ...

Arduino script to control a 5V Noctua A6x25 PWM fan (or any other 5V PWM fan) with the onboard Arduino Leonardo on an Udo Bolt. I got one of the first Udoo Bolts in 2019. As its fan was horribly noisy ...

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 ...

Among all the Arduino boards, the Uno is most folks' go-to choice, and for good reason. It's the perfect platform to get started with Arduino, it's capable enough to handle a wide range of tasks, and ...

Looking for a simple circuit to control the light intensity of Light Emitting Diodes (LEDs) or similar lighting sources? Here is an Arduino based circuit with three independent pulse width modulated ...

Abstract: This paper presents a simulation of a buck converter using pulse-width modulation (PWM) signal frequencies and duty cycles generated by an Arduino microcontroller for solar panel application ...
