I want to make band that can transmit heart-beat readings over bluetooth. As of now, I am using " http://www.ebay.in/itm/Pulse-Rate-S...343375?hash=item1c6567274f:g:baYAAOSwiYFXFL1S ", this sensor to make the project. I need help with the arduino board. Whether this one ( http://www.ebay.in/itm/Arduino-Nano...866092?hash=item3d2a4f9eac:g:d3kAAOSwcLxYGsQ9 ) works or not? And also any suggestions with the blutooth transmitter device more like HC-05..
Thank You

 

There is lots of information on arduino and HC-05 on WWW. For instance:
