# ESP32 Firebase Example

This Wokwi project demonstrates how to use an ESP32 to connect to a Firebase Realtime Database.

## Features

- Connects to a Wi-Fi network.
- Sends and retrieves data from Firebase Realtime Database.
- Uses the `Firebase_ESP_Client` library.

## Project Setup

1. Add the necessary components in the Wokwi simulator:
   - ESP32 microcontroller.
   - Required virtual peripherals, such as LEDs or sensors, if needed.

2. Install the following libraries in your Arduino IDE:
   - `Firebase ESP32 Client`
   - `WiFi` library (built-in for ESP32).

3. Ensure your Firebase Realtime Database has valid security rules and replace the following in the code:
   - `DATABASE_URL`: Your Firebase Realtime Database URL.
   - `API_KEY`: Your Firebase Web API key.

## Compilation

This project uses the Arduino framework for compilation. Ensure that:
- The project has a valid `setup()` and `loop()` function in the code.
- The correct board (ESP32) is selected.

## How to Run in Wokwi

1. Open the project in [Wokwi](https://wokwi.com).
2. Click the **Play** button to start the simulation.
3. Monitor the serial output for Wi-Fi and Firebase connection status.

## Troubleshooting

- If the project does not compile, ensure all required libraries are installed and the `setup()` and `loop()` functions are implemented.
- Verify Wi-Fi credentials and Firebase keys.
- Ensure the Firebase Realtime Database rules allow read/write access.
