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 goal of this project is to create a smart fan system that adjust its speed based on the current temperature. There are two modes: Manual and Automatic. Manual: The fan adjusts its speed based on ...

There are many annoying issues associated with desktop 3D printers, but perhaps none are trickier than keeping the machine at the proper temperature. Too cold, and printed parts can warp or fail to ...

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 ...

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