Abstract

ESP32 Zxspectrum is an open-source Internet of Things (IoT) project. This is the firmware for the ESP32 Rainbow project - an ESP32 based ZX Spectrum Emulator. The code is designed for my board, but will run on pretty much any ESP32 board. It is built using C++, ESP32. The complete source code is publicly available on GitHub under the GNU General Public License v3.0, making it a useful reference for students building an Internet of Things (IoT) mini project or final-year project.

1. Introduction

The code is designed for my board, but will run on pretty much any ESP32 board.

This is currently a work in progress and is under active development. So, I can't guarantee that the code will be stable.

The firmware lives in the firmware directory. Open this folder in Visual Studio Code and PlatformIO will take care of the rest.

2. Objective

This is the firmware for the ESP32 Rainbow project - an ESP32 based ZX Spectrum Emulator.

This project demonstrates how C++, ESP32 can be applied to a real-world Internet of Things (IoT) problem.

4. Technology Stack

C++ESP32

5. System Requirements

General requirements for this technology stack — check the README for exact versions.

  • Arduino IDE / PlatformIO or a C++ compiler (g++)
  • Target board (e.g. Arduino, ESP32) where applicable
  • Git (to clone the repository)

6. Installation & Setup

git clone https://github.com/atomic14/esp32-zxspectrum.git
cd esp32-zxspectrum

Full setup instructions are in the project README.

7. Future Enhancements

Suggested extensions you can add to make this your own project.

  • Add a mobile dashboard using Blynk or Firebase
  • Store readings in a cloud database for history charts
  • Add alerts via SMS / Telegram when thresholds are crossed

8. Viva / Review Questions

Common questions examiners ask for projects in this domain.

  1. Which microcontroller / board and sensors are used and why?
  2. How does the device send data (Wi-Fi, MQTT, HTTP, Bluetooth)?
  3. Where is the sensor data stored and visualised?
  4. How is power consumption managed?
  5. How would you secure the device and its communication?
