Build a Firebase Web Application to monitor and control your ESP32 and ESP8266 boards from anywhere in the world. All the data is saved on the Firebase Realtime Database. The web application is protected with login using email and password, and your database is protected using database rules.

What is Firebase?

Firebase is Google’s mobile application development platform that helps you build, improve, and grow your app. It has many services used to manage data from any android, IOS, or web application. We’ll focus on the building process and use the authentication, realtime database, and hosting services.

Web App Features

The following picture shows a sneak peek of the web app you’ll build throughout this ebook.

ESP32 ESP8266 Firebase Web App

Here’s a summary of the app’s main features:

  • The ESP32/ESP8266 can be controlled and monitored from anywhere using the Firebase Web App we’ll build.
  • The Firebase Web App is protected with login using email and password. Only an authorized user can access the data. Additionally, your database is protected by database rules.
  • The web app displays two buttons to control two GPIOs ON and OFF, two sliders to control PWM ouputs, an input field to insert a message, and a table to display sensor readings.
  • All the data is saved on the Firebase Realtime Database.
  • The web app gets the new readings from the database nodes that the ESP is publishing in.
  • The ESP boards detect database changes and update the peripherals states almost instantaneously.
  • You can access your Firebase Web App from anywhere in the world to interact with your ESP32/ESP8266 using a custom domain or the Firebase-generated domain name.
  • The web app is mobile responsive.

What’s inside the eBook?

The eBook contains the step-by-step instructions to build a Firebase Web App to control and monitor the ESP32 and ESP8266 boards. We’ll use the following Firebase services: Authentication, Realtime Database, and Hosting; and you’ll program the ESP32/ESP8266 boards to interact with the web app. The boards are programmed using the Arduino core.

The eBook is divided into 5 parts:

  • Part 1: Creating a Firebase Project—you’ll learn how to create a Firebase project and set up all the necessary services (Authentication and Firebase Realtime Database).
  • Part 2: Organizing your Database and Database Rules—we’ll show how to organize your database and set up database rules to protect your data.
  • Part 3: ESP32/ESP8266: Interacting with the Realtime Database—interact with the Firebase Realtime Database using your ESP32 and ESP8266 boards: learn how to read and send data to the database.
  • Part 4: Creating the Firebase Web App—set up HTML and JavaScript files to create the web app to control and monitor your boards.
  • Part 5: Hosting your Web App (Custom Domain Name)—host your web app and set up a custom domain name to access your web app anywhere. Alternatively, you can also access your app using the Firebase-generated domain (for free).

Here’s what you’ll have access to when you get the eBook:

  • eBook in PDF format (5 Parts, ~180 pages)
  • Source Code + Project Files (Arduino sketches, VS Code project folders, HTML and JavaScript files to build the web app)

Hi. I’m Sara Santos and  I create, write, and edit the tutorials and articles for the Random Nerd Tutorials blog. After the success of a couple of tutorials related to Firebase, we decided to create an eBook exclusively dedicated to Firebase with the ESP32 and ESP8266 boards. I’ve only started playing with Firebase recently. I only regret not having started earlier, because it is easy to use and opens many possibilities. I hope you love this project as much as I do.

See what others are saying

Thank you Rui. Anyone wondering whether you bring value can rely on my word. I’ve purchased hundreds of books over a 45 year career as engineer and entrepreneur. NONE of these books have approached your excellent method of teaching a subject. You have a rare gift as a teacher. Glad to have made the purchases.

Paul

I want to congratulate you on the manuals you have created, they are the best of the best that I have seen in many years. (… ) Your explanations are very clear and very detailed, as if you were a teacher…

Tino Fernández

I placed the order of these ebooks/courses and have downloaded the eBooks. The ebooks are very informative and very well presented, as is your website(…).

Robert Kyle

I want to thank you for the high quality of your projects. Too many others just list a series of tasks but not what to do when they do not go as planned. The detail that you have put into the writeups is amazing. I am working with my 10 year old grandson to help this interest in electronics and software. It would be much harder without your guides.

Doug Hogg

Thank you so much for all your excellent projects. I have been following you for several years and I have learned a lot and applied many of your ideas. Please continue all of this furthermore

Michael Moske

Your e-books and website are amazing – you and Sara are fantastic teachers and I am really enjoying my new hobby.
