Bugfix for Polar tutorial

[lizquilty]

I got one of the Polar HR kits which was great, however i ran into a problem when wiring things up.
The image at http://learn.adafruit.com/system/assets ... afruit.jpg shows the Polar board connecting to 2 different 3.3v connections on the flora in the top circuit diagram.
The Red one should actually be going to the GND instead of the other 3.3v

The lower image shows the correct diagram from the looks though. I checked with http://learn.parallax.com/KickStart/28048to verify i had it right before submitting bugfix (I mentioned it on twitter but was unsure if you would get it)

Also, unsure if its intentional, the code has the heart rate led flash commented out
//heartBeat();

That breaks things when not looking for it

Thanks for the feedback.

For future reference: On the left of the tutorial page there should be a feedback/corrections link. This is the best way to report tutorial issues.

Thanks Liz, I updated the diagram and fixed that line of code.
