Comments on: DIY Arduino Based Pulse Oximeter Part I (with video) http://tinkerish.com/blog/?p=181 doing tinkerish things with microcontrollers and embedded electronics Tue, 07 Sep 2010 22:33:10 -0500 http://wordpress.org/?v=2.8.5 hourly 1 By: mythgarr http://tinkerish.com/blog/?p=181&cpage=1#comment-410 mythgarr Tue, 07 Sep 2010 22:33:10 +0000 http://tinkerish.com/blog/?p=181#comment-410 @mike I meant that it would be great if you could post the source code and part 2, but it sounds like those bits never materialized. I'm shopping around on mouser trying to pick out the best LEDs and detectors for a DIY model, although I did find some fairly cheap (~$40) clip-on oximeters online that I might just tap into using serial or whatever protocol they happen to use internally. @mike I meant that it would be great if you could post the source code and part 2, but it sounds like those bits never materialized.

No, I did not finish the project. I could not get a satisfactory way to calibrate both the white and red LEDs. I think I would need to more carefully select the LEDs and use a constant current device to set the current for each (instead of just trying to tune them with resistors). I don't have an arduino sketch because, while I use Arduino hardware, I do not use there software stack. I program in straight C and use GNU toolchain. I'd be happy to share the code if you like. @mythgarr, this article was already posted on hack a day. No, I did not finish the project.

I couldn't find anything on the site or YouTube - it would be great if I could see how you ended up measuring both the red and IR wavelengths. Could you send me the arduino sketch for this? It would be really fantastic if you either posted the code here or gave me permission to submit it to hackaday for posting (giving you credit, of course). @mike

Thanks, Steffen hey, after reading your article i ordered
the parts too.
since yesterday i’m trying to reproduce your work -
without success :(
is it possible to mail me your arduino code, too?

Thanks,
Steffen

I bought all the required components, but i can't get the code right. Thanks! Can you please post the Arduino code for what you are doing?
