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 ...

This project implements a temperature-based fan speed controller using an Arduino Uno. The system adjusts the fan speed based on the ambient temperature, providing efficient cooling and energy ...

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 ...

The trend in electronics, particularly consumer electronics, is towards smaller products with enhanced combinations of features. Consequently, lots of electronic components are being shoehorned into ...

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 ...
