Description

Welcome to Raspberry Pi Full Stack Upgrade Project!

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. 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.

This course will stretch your skills.

I designed it for intermediate-level Makers that, ideally, have completed the original Raspberry Pi Full Stack course.

Please review the free lectures in the first section to find out more details about the course.

I'm looking forward to seeing you on the course.

Who this course is for:

Graduates of the original Raspberry Pi Full Stack course.
Makers looking for a non-trivial Raspberry Pi project.
Makers keen to up-skill their entire skill set, from the operating system to the Internet of Things.
