Temperature controlled Fan (AT89S52)

This Project is used to control the Fan speed according to the temperature and it also indicates the temperature. The system will get the temperature from the IC (DS1820) and it will control the speed according the values stored in the code.
The System is fully controlled by the microcontroller AT89S52. It is a popular 8 bit microcontroller.
All the above functions are monitored and controlled by the 8 bit microcontroller AT89S52.
