unsTABLE Pico Project

This project powers the unsTABLE Pico, a device that integrates an OLED display, buzzer, button, and MQTT functionality to create a dynamic interactive experience. The device connects to an MQTT broker and responds to JSON-based commands to display messages, manage notifications, and handle user interactions.

Features

• Wi-Fi Connectivity:

  • Automatically connects to a specified Wi-Fi network.

• MQTT Integration:

  • Subscribes to a specific topic and processes JSON messages with the following actions:
    • Action 0: Display a welcome message ("Hello, {name}") and start a timer.
    • Action 1: Display an alert on the screen for 1 minute without interrupting the timer.
    • Action 2: Display a goodbye message and clear the screen.
    • Action 3: Enable or disable notification sounds.

• Display Features:

  • Displays messages, QR codes, and timer.
  • Typing and scrolling animations for a smooth user experience.

• Buzzer:

  • Plays notification sounds with the ability to toggle sound on/off.

• Button Interaction:

  • Single-click: Display a QR code and clear after 5 seconds.
  • Double-click: Clear the display immediately.

Requirements

Hardware

• Raspberry Pi Pico or compatible board.
• OLED Display (SSD1306).
• Button and buzzer.

Libraries

• Adafruit GFX Library
• Adafruit SSD1306
• PubSubClient
• ArduinoJson

Setup

1. Clone the repository:

   git clone https://github.com/your-repo/unsTABLE-Pico.git```

2. Open the project in the Arduino IDE.

3. Configure the Wi-Fi and MQTT settings in config.h from config.h.example:

4. Compile and upload the code to your Raspberry Pi Pico.

5. Use an MQTT client (e.g., MQTT Explorer) to send messages to the subscribed topic.
