Hello everyone!

I am making a wireless pulse monitoring project. I am having difficulties in the detection of the sensor.
Here's the link of the code that I've copied: http://www.jamesrosko.com/2012/01/arduino-pulse-monitor.html

Here's my questions:
1. Distance from the sensors to a finger.
2. If the two sensors were across does the monitoring LED turns off?
3. What kind of sensor's should I use?
4. Is it ok to use the nellcor max-a pulse oxi clip. It has the same concept of a normal IR led and a photodiode. Link: http://www.diytrade.com/china/pd/7066705/Original_Nellcor_Disposable_Spo2_sensor.html

Really need your help guys.
Btw I'm a noob in using a arduino. Have pity on me. And time is running for my project smiley-cry.
Thanks in advance.

The guy in the instructables is using a PIC, but he shows how to develop the signal into something usable.
