## Project description
A smart fan controller use a STM32 MCU to cooling a LED light . The controller have 3 main function.
1.A GPIO generate a 25KHz PWM signal to control the fan speed.
2.The fan speed increase with temperature increasing.
3.When the temperature over 80 degress celsius, a buzzer sound. When the tmeperature over 100 degress celsius, the LED light power will be cut off
update on 16th May,2017
****
The NTC temperature has been read correctly. the DS18B20 digital sensor use to calibrate the NTC temperature. Due to the lookup table only have 1 degree accuracy, the NTC temperature lower than DS18B20 2 degrees.
****
In this application, the temperature does not need a high accuracy.
****
Further job would update the lookup table and expand the array. The interpolation algorithm can also increase the accuracy.
