Using a Temperature Sensor LM35 and an Arduino Uno Board ,I have made Temperature controlled DC fan. This can be used on its own or as part of larger projects.
I will upload the PCB design layout soon. I will try my best to answer all your questions. Thank you for watching!
Credits: I have got the circuit idea and design from the following link : https://goo.gl/qaQNW3 This video is only a demonstration of the same.
