Hello guys,
I would appreciate your help!
I would like to build a heart rate monitor in a wrist silicon bracelet. Do you guys have any suggestion on which PIC would do the job. I also need BT module and possibility to charge via USB (this is optional).
Just want to hear your feedback. Where should I be cautious, where to pay attention. I am building my first gadget, please do not kill my enthusiasm 
What on earth is a āsilicon braceletā?
One of these things.leon_heller:

Hello Maleni,
I have mentioned often donāt make it if you can buy it better & cheaper. [Amazon List
As a first project you should make something to amaze your friends but canāt buy it in the store.
No, those are silicone braceletsā¦

Aaahh, now I see !
@ the OP: Iām not sure where you can find a BT board small enough to mount into one of the above bracelets. Personally I"d be looking for an integrated MCU&BT module that can sample one analog channel. Is it your intention to use an IC meant for the monitoring job, something like whatās used in ā¦ ?

I donāt know what kind of detailed data youāre looking for, but if itās simple heart rate perhaps a BLE solution might work. They are intended to send short packets of data intermittently.

To make the circuitry fit around a wrist, Iāll opine youāre looking at several āboardsā connected via flex print. Not the stuff usually done by beginners (itās $$$s).
