How to setup firebase Cloud Real time database for Esp32 IOT projects

Firebase is a popular cloud-based database and backend service that can be used to build dynamic and real-time applications. It can be used with various platforms and devices, including the ESP32 microcontroller. In this blog post, we will guide you through the steps to set up Firebase for ESP32.

Before starting, make sure that you have an active Google account, as Firebase is owned and managed by Google.

Step 1: Create a Firebase Project
To start, create a new Firebase project in the Firebase console. Once you have created a project, you can navigate to the "Database" section of your project to set up the database.

Step 2: Configure Firebase Database Rules
Firebase Database Rules determine who can read and write to your database. By default, the rules are set to read and write by any authenticated user. However, this is not secure and you should change the rules to fit your application's requirements. You can set the rules by navigating to the "Rules" tab in the Firebase console.

Step 3: Create an ESP32 project in the Arduino IDE
To connect the ESP32 to Firebase, you need to use the Firebase Arduino library. Start by installing the library by navigating to Sketch - Include Library Manage Libraries in the Arduino IDE. Search for the Firebase Arduino library and click the "Install" button.

Next, create a new project in the Arduino IDE and import the Firebase Arduino library by going to Sketch Include Library Firebase Arduino.

Step 4: Connect the ESP32 to Firebase
Once you have set up your Firebase project, you can connect the ESP32 to Firebase using the Firebase Arduino library. Here's an example code snippet to get you started:

In this code snippet, you need to replace the placeholders with your own Firebase project credentials and Wi-Fi network details.

Once you have uploaded the code to your ESP32, you can check your Firebase database to verify that the data is being written successfully.

In conclusion, setting up Firebase for ESP32 is a simple process that involves creating a Firebase project, configuring the Firebase database rules, and connecting the ESP32 to Firebase using the Firebase Arduino library. Once you have set up Firebase, you can build powerful and dynamic applications with ease.

Amir Bhai, your code is different from the previous video to this ? String FIREBASE_HOST =
String FIREBASE_AUTH - in this you are using API key
