Mini LED Monitor Arduino Nano Programmable Display

🖥️ Mini LED Monitor with Arduino Nano – A Compact Programmable Display

This project is a compact, programmable LED mini monitor powered by an Arduino Nano and equipped with Bluetooth BLE capabilities. Housed in a sleek 3D-printed enclosure, it works perfectly as an interactive desktop display for animations, status indicators, counters, or ambient lighting effects.

✨ Features:

• LED Screen: Built with addressable LEDs (e.g., WS2812B) behind a frosted diffuser for smooth, soft lighting.
• Arduino Nano: The main controller that manages display modes and Bluetooth communication.
• Bluetooth BLE Module: Enables wireless control and data transfer (e.g., via smartphone apps).
• Momentary Button: Lets you cycle through different display modes with a single press.
• Startup Screen + Multiple Modes: Shows a welcome animation when powered on, followed by user-programmable display modes such as Pomodoro timer, notification panel, ambient RGB animations, etc.
• USB Powered: Simple 5V power via any USB source.
• ON/OFF Slider Switch: A physical toggle switch for convenient power control.
• Voltage Dividers Included: Ensures safe logic level conversion for the BLE module.

🛠️ Use Cases:

• A personal desktop widget: clock, timer, reminders.
• A decorative RGB panel with customizable lighting effects.
• A system status indicator or productivity assistant.
• A beginner-friendly platform for learning microcontroller programming and LED animations.

🧰 What’s in the 3D Model:

• A sturdy base housing all the electronics.
• Ergonomic form with cutouts for the button and switch.
• A slightly tilted LED screen holder for better visibility.
• Sleek, modern design combining black with a vibrant accent color (e.g., blue).
