Fan Speed Controller

This project is an AVR microcontroller-based fan speed controller that adjusts the fan speed based on the temperature readings from a temperature sensor.

Project Structure

Files

• include/fan_controller.h: Header file for the fan controller functions.
• include/temperature_sensor.h: Header file for the temperature sensor functions.
• src/fan_controller.c: Source file for the fan controller implementation.
• src/temperature_sensor.c: Source file for the temperature sensor implementation.
• src/main.c: Main application source file.
• Makefile: Makefile for building the project.

Functions

Fan Controller

• void fan_controller_init(void): Initializes the fan controller.
• void fan_controller_set_speed(uint16_t temperature): Sets the fan speed based on the temperature.

Temperature Sensor

• void temperature_sensor_init(void): Initializes the temperature sensor.
• uint16_t temperature_sensor_read(void): Reads the temperature from the sensor.

Building the Project

To build the project, run the following command:

make

This will generate the fan_speed_controller.hex file.

Flashing the Firmware

To flash the firmware to the microcontroller, run the following command:

make flash

• Ensure that the microcontroller is connected to /dev/ttyUSB0.

Cleaning the Build

To clean the build files, run the following command:

make clean
