It is a system to control the fan speed its interfaces with a temperature sensor, dc motor, and LCD to display the reads of the temperature. The (fan) motor speed changes according to the temperature read from the LM35 sensor.
This Link will show running the project hardware connection on the ATmega32 microcontroller after the HEX file has been burned Fan with 0% and 25% of maximum speed.
The second Link Fan with 50% and 75% of maximum speed
This Link will show running the project on Proteus Simulation after the HEX file has been burned Link is here
All System Requirements you needed its in the snipping picture:
