The sensor takes pulse and oxygen level readings from your fingertip, then shows the resulting numbers on an RGB NeoPixel shield. Although the unit is not medically approved to diagnose or treat medical conditions, it’s a neat display method, and it even features heart and lung icons to indicate what you’re seeing. Code for the build is available on GitHub.
