ESP-NOW Button Link
Wireless · Board: ESP8266 · Day 55 of 100
A button press on one ESP8266 lights an LED on another via ESP-NOW. Wireless input-to-output in its purest form.

How it works
Pressing the button fires an ESP-NOW packet straight to the paired board, which lights its LED on receipt. There is no connection to establish and no network to join — the purest possible wireless input-to-output path, and a perfect first ESP-NOW experiment.
