🧩 Multifunction Device – ESP32

This project is a multifunction electronic device built around an ESP32 microcontroller. It integrates several independent features into a single standalone system with a TFT display, physical buttons, Wi-Fi, and Bluetooth connectivity.

The device was developed as an experimental and educational project, combining hardware interaction, wireless communication, graphical interfaces, and real-time features on the ESP32 platform.

✨ Features

The device includes the following operating modes:

• Clock Mode
  Displays the current time obtained automatically via Wi-Fi. If automatic synchronization fails, the time can be configured manually through a web interface hosted by the device.

• Photo Frame (Gallery) Mode
  Displays a slideshow of images on the TFT screen, cycling automatically every few seconds.

• Bluetooth Speaker Mode
  Enables Bluetooth audio output, allowing the device to function as a wireless speaker when paired with a phone or computer.

• Flappy Bird Game Mode
  A simple implementation of the Flappy Bird game adapted for the TFT display and button-based controls.

All modes are accessible through a main menu and can be exited at any time using the control buttons.

🔧 Hardware Overview

• Microcontroller: ESP32
• Display: TFT RGB display
• Controls:
  • Select button (menu navigation / exit)
  • Start button (confirm / action)
• Connectivity:
  • Wi-Fi (time synchronization and web configuration)
  • Bluetooth (audio output)
• Power Supply:
  • 5V DC input (2.1 mm connector)
  • Power switch on the back panel

🎛️ User Interface and Controls

• The left button is used to navigate through the menu and exit modes.
• The right button is used to start or interact with the selected function.
• The main screen displays system messages such as connection status, IP address (for configuration), and active mode information.

⏱️ Time Configuration

The device attempts to obtain the current time automatically via Wi-Fi.

If this is not successful:

1. The screen will display the device’s IP address.
2. Enter this IP address in a web browser on the same network.
3. A configuration page will allow manual adjustment of the time and time zone.

🔌 Power Requirements

The device must be powered using a 5V power source. Using an incorrect voltage may damage the hardware.

🗂️ Project Structure

This repository contains:

• The complete firmware for the ESP32
• Display logic for multiple modes
• Input handling for physical buttons
• Wireless communication logic (Wi-Fi and Bluetooth)

Due to the number of integrated features, the codebase is relatively dense and tightly coupled to the hardware.

🎯 Purpose and Scope

This project was developed as a multifunction prototype to explore the capabilities of the ESP32 in a single embedded system. It is intended for learning, experimentation, and demonstration purposes rather than as a production-ready device.

Note:
This project was developed within a limited time frame (approximately one month).
The main focus was on feature integration, hardware interaction, and overall system stability rather than extensive refactoring or long-term maintainability.
