Project1: CPU FAN Controller based on CPU temperature

This project is required to control 5 or 12v FAN that cools a CPU.
The speed of the fan must be adopted according to the CPU
temperature. At least there are 3 speeds.
PIC microcontroller must get an analog signal from a thermostat
connected to CPU and convert this signal to digital and then generate
PWM signal to control the speed of the fan. In addition to that, The
temperature (Celsius) and the speed (round per minute rpm) must be
shown on an LCD and must be updated every second.

 

What PIC are you using?
Where are you stuck? What have you done so far? and When is it due?

 

PIC16F88 + LM35 + 2 rows 16 chars LCD, will solve your problem.

Alberto

And the ability to code, and having the datasheets for the appropriate components.

 

PIC16F88 + LM35 + 2 rows 16 chars LCD, will solve your problem.

Gonna need an op amp to amplify the LM35 output for the A to D.

 

I'm use pic18f

pleas quickly...


thank you...

 

Have you obtained the data sheets for all the devices? And have you read them to understand how the individual parts function?
