## Getting Started 🚀
1. **Download the repository**: 🟢 Click "Clone or download" on the green button above.
2. **Open the project**: 🖥️ Use Altium Designer to open the `.PrjPCB` file located in the main directory.
3. **Schematics**: 📜 The `schematic.SchDoc` file shows the electrical connections and components used in the design.
4. **PCB layout**: 🧩 The `PCB.PCBDoc` file represents the physical layout of the components on the printed circuit board.
5. **Generate BOM (optional)**: 🛒 Use Altium Designer's BOM generation features to create a list of required components.
## Additional Information ℹ️
- **Firmware**: This repository does not include the firmware. You can program the board using the Arduino IDE by installing the Digispark ATTINY85 board package from the boards manager.
- **Assembly instructions (optional)**: 🔧 Consider adding a separate document or webpage with detailed instructions on soldering and assembling the PCB (if applicable).
- **License**: 📄 Specify the open-source license used for the design files (e.g., MIT License).
