Build the device as instructed in the blueprint and instruction manual provided. Then make sure you have the .ino file running on your arduino device (upload with Arduino IDE). I used the Arduino from ...

This project demonstrates a temperature-based fan control system using an Arduino Uno. The system reads ambient temperature via a DHT11 sensor and adjusts the speed of a 12V exhaust fan accordingly ...

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 ...
