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 project illustrates the control of a PC fan speed and using an Arduino microcontroller to read a LM35 temperature sensor. The use of an optocoupler is covered along with Pulse Width Modulation ...

Traditional fans run continuously or require manual control, often leading to energy waste. This project creates a smart solution: a temperature-sensing fan controller that turns ON/OFF or adjusts ...

The Arduino reads the temperature from DHT22 and adjusts fan speed using PWM. The current temperature is shown on the LCD.

I'm working with a uC controlled fan/temp contoller. In that regard I'm very interested in how to control temperatures the best way. The board will be able to measure 8 temp probes and control 8 fans ...
