# Flask LED Control

Day 44 of the 100 Days 100 IoT Projects collection. Board: ESP32.

A Python Flask web app toggles an LED on ESP32 or Pico W. Full-stack IoT with a real backend framework.

## How it works

A Flask application on your computer exposes a web route that the microcontroller polls over HTTP. When you click the page's button, the next poll carries the new state back and the LED flips. It is genuine full-stack IoT: browser frontend, Python backend, embedded client.

## What you'll learn

- Flask web backends
- HTTP polling pattern
- Full-stack IoT architecture
- Frontend/backend separation
