(not sure if this is the right place to ask this question)
Hi everyone!
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 sure you can find smaller BT modules, but you are going to have to do research to determine compatibility. There are plenty of small, inexpensive Arduino boards: Nano, Mini Pro, etc. that will be possible candidates.
Can one really calculate the human pulse every 1 second? My wife is a nurse, the best I have seen her do it is around 10 seconds... but, of course, she does not use anything other than her wristwatch.
