During the ESP32 project video, I covered the following topics:
00:49 Quick demo on ESP32 Firebase Web server relay control project.
01:49 Required components for the ESP32 IoT project.
02:00 Circuit diagram of the ESP32 Relay control project.
03:16 Configure the Firebase Realtime Database and Web App for ESP32.
06:15 Source codes for the ESP32 Firebase project.
08:38 Prepare the Web-Dashboard HTML for ESP32 Firebase project.
09:47 Deploy the Web-Dashboard HTML in GitHub.
11:20 Steps to access Web UI to control the relays from mobile.

Project Key Features:
Control 4 relays using Firebase Realtime Database, a live Web Dashboard & Manual Switches.
Real-time sync between ESP32 Firebase and Web Dashboard.
Web dashboard hosted on GitHub for global access.
Login/logout functionality with responsive UI.
Automatic feedback updates from manual control to Firebase.

Required Components for the ESP32 control relay PCB V3:
1. Relays 5v (SPDT) (4 no)
2. BC547 Transistors (5 no)
3. PC817 Optocouplers (4 no)
4. 510-ohm 0.25-watt Resistor (5 no) (R1 -- R5)
5. 1k 0.25-watt Resistors (7 no) (R6 -- R12)
6. LED 5-mm (7 no)
7. 1N4007 Diodes (4 no) (D1 -- D4)
8. Hi-Link HLK-5M05 AC to DC converter.
9. Terminal Connectors
10. Push button (1no)

Important Points:
If you not able to control the relays or monitor the relay status on Web-Dashboard, then please close the dashboard and delete the browsing history, then try again.
For the authentication in Firebase Realtime database you can use any dummy email id and password.
