So I’ve never used an Arduino before. I’m trying to learn how to measure Heart Rate and Oxygen Saturation using it.

I’ve followed this tutorial: https://www.youtube.com/watch?v=W_3ljVlt7Sk

The code is here: https://drive.google.com/drive/folders/1qAQCRKpHryYdSZ8oK2nJpihT4GcQZmuS

Nothing is working so I need help.

When I try to upload the code to Arduino, the following error happens:
