"github_readme_excerpt": "# Lid Angle Sensor\n\nHi, I\u2019m Sam Gold. Did you know that you have ~rights~ a lid angle sensor in your MacBook? [The ~Constitution~ human interface device utility says you do.](https://youtu.be/wqnHtGgVAUE?t=21)\n\nThis is a little utility that shows the angle from the sensor and, optionally, plays a wooden door creaking sound if you adjust it reeaaaaaal slowly.\n\n## FAQ\n\n**What is a lid angle sensor?**\n\nDespite what the name would have you believe, it is a sensor that detects the angle of the lid.\n\n**Which devices have a lid angle sensor?**\n\nIt was introduced with the 2019 16-inch MacBook Pro. If your laptop is newer, you probably have it. [People have reported](https://github.com/samhenrigold/LidAngleSensor/issues/13) that it **does not work on M1/M2 devices**, I have not yet figured out a fix.\n\n**My laptop should have it, why doesn\u0027t it show up?**\n\nI\u0027ve only tested this on my M4 MacBook Pro and have hard-coded it to look for a specific sensor. If that doesn\u0027t work, try running [this script](https://gist.github.com/samhenrigold/42b5a92d1ee8aaf2b840be34bff28591) and report the output in [an issue](https://github.com/samhenrigold/LidAngleSensor/issues/new/choose).\n\nKnown problematic models:\n\n- M1 MacBook Air (the wedge-shaped one)\n- M1/M2 MacBook Pro with Touch Bar\n\n**Can I use this on my iMac?**\n\n~~Not yet tested. Feel free to slam your computer into your desk and make a PR with your results.~~\n\n[It totally works](https://github.com/samhenrigold/LidAngleSensor/issues/33). If it doesn\u0027t work for you, try slamming your computer harder?\n\n**Why?**\n\n~~A lot of free time. I\u0027m open to full-time work in NYC or remote. I\u0027m a designer/design-engineer.~~ https://samhenri.gold\n\nI am now employed but I\u0027m still doing this for the love of the game.\n\n**No I mean like why does my laptop need to know the exact angle of its lid?**\n\nOh. I don\u0027t know.\n\n**Can I contribute?**\n\nI guess.\n\n**How come the audio feels kind of...weird?**\n\nI\u0027m bad at audio.\n\n**Where did the sound effect come from?**",
