If you are referring to the single, thick wire, that is just one turn. The fine wire with many turns is pre-wound but I believe it has 350 turns.

Working! I still want to make some changes to the way the screen draws. I'd prefer it not to clear each time it gets to the end. I'm going to try and have it erase just ahead of the wave form. I also printed a tray/battery holder for it. Still working on the enclosure for the pulse sensor. Right now the pulse sensor is giving such a weak signal it isn't showing well on the OLED. Just more to tinker with!
This is my first Hackerbox and I'm having a great time. It is assembled and working so now I'm starting to explore how to clean up the 60 hz interference, make better use of the OLED, etc. Question: There are a few parts in the kit that seem unrelated such as the heat shrink tubing and the TRRS breakout. What are those for?
I see! Gives me an idea for converting the ECG leads to alligator clips for different electrode pads I have access to. I'm now in the process of getting the wave form to the OLED and having some success. Now just need to figure out how to filter out the 60 Hz noise. What a great box!

Great idea. I have now done this in a couple closets that have very poor lighting. I simply used the LED light strips, a power supply and magnetic switches. It makes a huge difference.
