Meeting Room Reservation System

A comprehensive, Retro/Matrix-styled reservation system originally designed for a FabLab/Meeting Room. It features a lightweight PHP web interface and hardware integration for E-paper status displays.

🚀 Features

💻 Web Interface

• Desktop Dashboard (index.php):
  • "Retro/Cyberpunk" aesthetic.
  • Weekly calendar view (via FullCalendar).
  • Real-time status dashboard (Free/Busy, Current Event, Next Event).
• Mobile Version (mobil.php):
  • Optimized for touch devices.
  • Simplified daily view.
  • Add/Edit reservations on the go.

🔌 Hardware Integration (IoT)

• E-Ink Display (fablab.ino):
  • C++ firmware for ESP32/Arduino.
  • Fetches data from the API to show room status on a low-power E-paper screen.
  • Smart WiFi connection handling and OTA updates ready.
• Magic Mirror / Info Screen (mirror.php):
  • High-contrast, large-font display mode.
  • Designed for dedicated tablets or smart mirrors outside the room.

⚙️ Backend

• Zero-Config Database: Uses a flat JSON file (events.json) for data storage. No MySQL/PostgreSQL required.
• JSON API (api.php): Exposes normalized data for 3rd party integrations or hardware.

🛠️ Installation

1. Server Requirements: Any web server with PHP 7.4+.
2. Upload: Copy all files to your web server directory.
3. Permissions:
   • Ensure events.json is writable by the web server.
   • Example command: chmod 777 events.json (or chown www-data events.json depending on your security needs).

🔧 Configuration

Timezone

By default, the system is set to Europe/Prague. You can change this in api.php:

date_default_timezone_set('Europe/Prague');

Hardware (ESP32)

1. Open fablab.ino in the Arduino IDE.
2. Install required libraries: GxEPD2, Adafruit_GFX, ArduinoJson.
3. Fill in your WiFi credentials and server URL in the configuration section:

   WifiInfo networks[] = { {"YOUR_SSID", "YOUR_PASS"} };
   const char* server = "your-domain.com";

4. Upload to your board.
