Circuit diagram for Arduino Nano

[nubecks]

Hey Jeff,

This is an interesting project and could you please upload the circuit schematic when using Arduino nano instead of the Attiny85? In the folder nanopulsePPG I can find code right?

Thank you!

I don’t have a circuit diagram but you can see the connections from the picture in the nanopulsePPG directory.

Thank you for your reply, yes for most of the connections it is clear. The green and the purple wire connections are the ones that are not clear. Could you please verify that?

Green wire: From xx to yy
Purple wire: From aa to zz

Thank you!

Green wire goes from one side of the button to -ve.
White wire, your purple? Goes from other side of button to D3

Hi Jeff,

Thank you for your info and now it works. One follow-up question. How can I stream the data directly to a .csv file? I have the Excel data streamer, but I appreciate some help with the arduino code. What code snipped should I add to the nanoPulsePPG?

Thanks for your help in advance!
