In this tutorial, you’ll learn how to control a 4‑wire BLDC (PWM) fan using an ESP8266 and MicroPython.
We’ll cover how to generate PWM signals for speed control, read tachometer feedback for RPM measurement, and integrate everything with MicroPython for easy development.
🔧 Project Steps:
– Types of DC fans and how each one works
– How to identify the wiring of a 4‑wire DC fan
– Connections to the ESP8266
– Demonstration with a 12V power supply
