# Nano Clock

A compact, internet-connected digital clock built with the Seeed Studio XIAO ESP32S3 and a 0.91-inch OLED display. The clock synchronizes time using NTP (Network Time Protocol), ensuring accurate timekeeping without the need for an RTC (Real-Time Clock) module. The design is inspired by [Scott Yu-Jan's iPhone Standby Mode Dock](https://www.youtube.com/watch?v=L3nWw8qSYgk&t=30s), blending minimalism with functionality.

## Features and Future Improvements

This project is considered complete, the following outlines the current features and potential future improvements:

### Current Features

- Internet Time Sync: Fetches real-time data using NTP for accurate timekeeping.

- OLED Display: Displays time in HH:MM:SS format on a 128x32 SSD1306 OLED.

- Compact Design: Small footprint which ideal for desks.

### Future Improvements

- Offline Mode with Manual Configuration Button: Allow users to set the time manually without requiring an internet connection.

- Temperature Sensor Integration: Add a sensor to display real-time temperature readings on the OLED.

- IoT intergration: Look at possible IoT intergration to sending and recieving messages or alerts.

- Custom PCB Design or Improved design: Research creating custom PCB or design case for easier assembly.

## Getting Started

1. **Get the Components** - Purchase the components from the BOM and a compatible board.

2. **3D Print the Case** - Download the STL files for your chosen configuration and print them on a 3D printer.

3. **Assemble the Hardware** - Solder the components and assemble the board and case.

4. **Upload the Firmware** - Connect the board via USB and upload the firmware.

## Required Components

The following are the required components to build the nano clock:
