This short video shows a real-world MQTT IoT setup using two ESP8266 modules — one sends AES128-encrypted data, and a custom broker decrypts it using a secure key file.

✅ Real-time LED control via MQTT Explorer
✅ Visual confirmation with blinking blue LED
✅ Data saved to CSV or database, viewable in Node-RED, Grafana, or Power BI
✅ Built on MQTT features:
• Lightweight protocol
• Persistent connections
• QoS reliability
• Retained messages
