Spring-Powered Extended Fan

This project combines a spring-loaded mechanical fan with an ESP32 microcontroller to create an adjustable cooling device that can be controlled remotely or via local sensors. The spring mechanism provides consistent airflow while the ESP32 manages power delivery and enables smart features like scheduling, speed adjustment, and integration with home automation systems.

The guide includes a complete wiring diagram showing how to connect the ESP32 to a motor driver and DC fan motor, a detailed parts list with spring specifications, and step-by-step assembly instructions. Firmware code is provided to get the device running with basic control options, giving makers a solid foundation to customize the project for their specific cooling needs.
