Materials are listed in the materials section, however they are listed here too.

Microcontroller: Arduino (originally Raspberry Pi, later switched for compatibility)

DC Motor & Fan – Main cooling mechanism

Motor Driver (L298N / DRV8871) – Controls the DC motor speed

Micro Servo (SG90 / MG90S) – Controls airflow direction by oscillating the fan

Temperature Sensor (BME688) – Monitors temperature, humidity, and air quality

OLED Display (SSD1306 / SH1106) – Displays real-time temperature, fan speed, and status

Power Supply – Compatible adapter or battery pack

3D-Printed Motor & Servo Holders – Secure mounting for components

Jumper Wires & Breadboard – For wiring connections

You will want to attach the small plastic fan to the end of your motor

Following any online instructions, wire the DC motor correctly and set up the code. 

You will want to wire the temperature sensor connecting it to the Arduino. Arduino already come with a few examples on how to do this that will be useful.

You will also want to set up your thresholds such that the DC motor will turn off or on for certain temperatures.

Wire the Micro servo to the Arduino and make sure it is working. Again, simple instructions for this can be found online.

Attach the display to the Arduino following simple online instructions. Set the display to show the room temperature read by the BME sensor.

Look online for any designs you like or design your own 3D printed holder for the Micro servo--so that it doesn't fall over, and for the DC motor--so you can attach it to the micro servo. A lot of good designs can be found on Thingiverse. 

Attach all the 3D printed designs and troubleshoot any issues you might be having.
