Hi guys,
i need some help to do this project. but i have no idea how to do it..can anyone help me?i want to use phototransistor and ir led..but i dont know its oky or not.
about the bluetooth connection can i use xbee shield?
Hi,
There are breakout boards available that have both the LED and receiver built onto them as pulse oximeters if that will make it easier for you.
but i dont know its oky or not.
I'm not sure why it wouldn't be okay - perhaps you need to give more detail on why it might not for your project?
about the bluetooth connection can i use xbee shield?
If you intend to use a Uno with a shield there are shields available which will take a bluetooth bee (or even two, in the case of the Seeed Studio one). You might find the bee option is more expensive than a bluetooth shield though. And there are certainly less expensive ways of adding bluetooth than using a shield too.
Cheers ! Geoff
thank you for reply sir..
about the board can u give the link so i can survey?
and the coding is available or not?
I see them on eBay often. I haven't used one that I can recommend however.
did u have done this project sir?
can i have the detail to be my references?
i don't have any idea to do now..huhu 
I have not done this project. Break it into pieces though and you'll find it's quite straightforward.
sir the oximeter can read the value by looking at brighness of the light through the tissue right?how can i relate the value of heartbeat and oxygen saturation?any formula?and it is write in the coding right?
You shouldn't have any trouble finding heaps of information on this and examples from others who have done similar projects (there are actually heaps of posts containing 'pulse oximeter' [on the forums you're reading now](http://pulse oximeter site:http://forum.arduino.cc)) so you shouldn't have too much problem once you have a look at what others have achieved, and build from their experience.
All the best,
Geoff
