This project demonstrates how to read **analog voltage values** from a **variable resistor (potentiometer)** using the **ADC (Analog-to-Digital Converter)** on the **ESP8266** board with **MicroPython**. The sensor’s analog output is connected to the **A0** pin, and the digital value (0–1024) is printed on the Thonny IDE console.

This project demonstrates how to control the **brightness of an LED** using a **variable resistor (potentiometer)** connected to the **ADC** pin of the **ESP8266** board. The analog voltage from the potentiometer is read and converted into a **PWM (Pulse Width Modulation)** duty cycle to adjust the LED brightness smoothly.
