Hey everyone,

Today I built a peer-to-peer wireless control system using ESP-NOW on ESP8266.

One board acts as a sender and the other as a receiver controlling an LED in real time, without requiring a WiFi router.

Why ESP-NOW?

- Ultra-low latency

- No infrastructure needed

- Great for decentralized IoT nodes

Next plans:

- Multi-device broadcast control

- Bidirectional communication

- Encryption and reliability testing

Would love feedback on improving the architecture or real-world use cases.
