Everything you need to build this project can be found under my "Gateway" smartwatch project on https://www.roboticworx.io for free! (https://www.roboticworx.io/p/build-the-ultimate-smartwatch-lidar)
(Remember, you can download anything you'd like for yourself but you CAN'T sell it. All my work is licensed, thanks!)
Thanks for reading and happy making!
Best regards, Justin
