# ESP-NOW LED Control

Day 54 of the 100 Days 100 IoT Projects collection. Board: ESP8266.

Toggle an LED across two ESP8266 boards with ESP-NOW peer-to-peer radio — no router needed. Low-latency wireless without a Wi-Fi network.

## How it works

The two ESP8266 boards pair directly as ESP-NOW peers using each other's MAC addresses — no router, no Wi-Fi network at all. A toggle command jumps straight from one radio to the other with minimal latency, and the receiving board flips its LED.

## What you'll learn

- ESP-NOW protocol
- Peer-to-peer radio
- MAC address pairing
- Router-free wireless
