~ Generally, electronic devices produce more heat.
So this heat should be reduced in order to protect the device.
~ The aim of this project is to design a Temperature Controlled DC Fan
which automatically turns on a DC Fan when the temperature increases above
a certain limit and also the temperature limit can be changed anytime using input from UART.
If the temperature exceeds 35 degree Celsius -> The microcontroller will turn on the relay. (ambient temperature limit of laptop) Now, 12V DC source is connected which starts the fan.
If the temperature drops below 35 degree Celsius -> The microcontroller will turn off the relay , but the fan speed will slow down gradually which further reduces the temperature.
