Install [`uv`](https://docs.astral.sh/uv/)\n2. Create a virtual environment with `uv venv --system-site-packages`\n\n\u003e [!IMPORTANT]\n\u003e The `--system-site-packages` gives our virtual environment access to system-wide packages.\n\u003e This is necessary because this script relies on the RPi's GPIO, and hence on `gpiozero` -- a system-wide package.\n\n3. Install the necessary libraries with\n\n```bash\nuv pip install -r requirements.txt\n```\n\n4. Ensure you're able to print to the screen by running `uv run hello_world.py`\n\n# Content\n\n```bash\n├── data/ # Where the fonts \u0026 quotes are stored, sourced from https://github.com/JohannesNE/literature-clock and https://fonts.google.com/\n├── 3d-models/ # 3D models of the cases\n├── notebooks/ # Notebooks used to prepare the data and develop\n├── utils/ # Utils for the script to run\n├── tests/ # pytest\n├── main.py # Main script\n├── hello_world.py # Script displaying \"Hello World\" on the screen\n├── full_refresh.py # Script performing a full refresh on the screen (see https://time-teller.arthurgassner.ch/#step-3-display-something-on-the-screen)\n├── partial_refresh.py # Script performing a partial refresh on the screen (see https://time-teller.arthurgassner.ch/#step-3-display-something-on-the-screen)\n├── clear_screen.py # Script clearing the screen\n└── README.md \n```\n","funding_links":[],"categories":[],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farthurgassner%2Ftime-teller","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Farthurgassner%2Ftime-teller","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Farthurgassner%2Ftime-teller/lists"}
