(not sure if this is the right place to ask this question)
I got an arduino board and i'm about to buy a bluetooth shiled for it. The thing is:
I wanted to create a bracelet (like a wristband) to check my pulse every second and send the values via bluetooth to arduino. I got the pulse sensor:
I just needed a battery to be always connected and a way to connect it to a microprocessor or anything else to keep the values and send it via Bluetooth. The problem is that i need a small Bluetooth receiver on the bracelet. And because i dont know very well how to program Bluetooth devices i'm kinda "floating in the river". What kind of micro controller do i need to store the values and what kind of bluetooth receiver?
I'm free to help anyone doing this project $$$
still, i would like to know how to do it.
Thank you once more for your time
p.s.: see this project? It sends data wirelessly . its something like that
