Raspberry Pi Full Stack Upgrade Project is an opportunity to take the Raspberry Pi Full Stack application to the next level.

 

Learn how to upgrade the hardware and software of the original Full Stack application as well as your Maker soft and hard skills and knowledge. 

In the original Raspberry Pi Full Stack course, you learned how to build an application that integrates microcomputers, microcontrollers, sensors, radio transceivers, web servers, a database, and Cloud services.

This course will teach you how to upgrade this application with new hardware and software.

The upgraded Full Stack application utilises the Raspberry Pi Zero 2 W single-board computer and the ESP32 microcontroller - although you can use any Raspberry Pi and Arduino-compatible board.

The two nodes communicate via a modern radio transceiver (the HC-12). They can sense their environment, show their status on an organic LED display and a web interface, log data on the Cloud, and trigger notifications when specific conditions arise.

By completing this course, you will gain and improve soft and hard knowledge and skills. You will become better at the analysis, design, and planning required when working on large projects.

And you will learn how to integrate sensors, displays, and local and Cloud communications using Raspberry Pi and ESP32 or Arduino boards.

Here are some of the elements of the upgraded Raspberry Pi Full Stack application:

  • The Linux operating system and the command line.
  • The Python programming language.
  • The Raspberry Pi General Purpose Input Output pins (GPIOs).
  • The Nginx web server.
  • The Flask Python web application microframework.
  • jQuery and CSS for creating user interfaces.
  • Timezone management with Python and Javascript.
  • Charting with Plotly and Google Charts.
  • Datalogging with Google Sheet.
  • Applets and notifications with IFTTT.

There is no other course on the Internet that I know about that offers all this content, in a single project.

This course has a prerequisite: Raspberry Pi Full Stack

In the original Raspberry Pi Full Stack, you learn how to build the Full Stack application from the ground up, in detail.

If you have not completed this course, I recommend that you do so before attempting Raspberry Pi Full Stack Upgrade Project.

Learn more about Raspberry Pi Full Stack, and enroll.


In this course, you will also learn how to setup a remote wireless Arduino sensor node, and collect data from it. Your Raspberry Pi web application can then process the Arduino node data in the same way it processes data from its on-board sensor.

What hardware will you need?

This course requires a Raspberry Pi with a model B header, an ESP32 (or any other Arduino-compatible board) and a few other components.

This hardware is not included in this course, and you must source it separately.

You can find a complete listing of the hardware you will need for this course in the course hardware page.

In this project, you will have the opportunity to work on your Maker soft skills on an existing project. Rather than starting from a blank slate, you must evaluate what you already have, and decide what to keep, what to throw out, and what to change.

In this course, you will improve your ability to build a full-stack application based on the Raspberry Pi, the ESP32 and a combination of software tools and technologies.

In the Raspberry Pi Full Stack Upgrade course, you will build on the hard skills you learned in Raspberry Pi Full Stack and add new ones. Most notable of those new skills are the ability to use the BME280 sensor, the HC12 transceiver, and the SD1306 OLED display in your Raspberry Pi and ESP32 projects.

You will also gain new skills in maintaining, modifying, and extending a full-stack application; an essential skill often overlooked in technical and technology education.
