Here's some background
So I want to build some bluetooth scales using arduino. I understand I will have to have the atmega chip sleeping for the majority of the time as well as removing some regulators if I want the scales to be able to be powered from AA batteries.
My load cells are only 10kg each (I'll use 2, one on each side) and all the arduino will do is send a string to my mobile phone (android) of the load cell voltage (I'll calibrate on my phone) via bluetooth.
In the prototype I am building I have a HC-06 module, and my load cells work with the HX-7 module.
So I have two questions:
Are these the right modules for me to be using if I want to convert this project to be battery powered?
How does bluetooth pairing work with the arduino chip sleeping? Can the bluetooth wake the arduino up when needed?
