{QUESTION} Battery Sensor example
-
Hi,
I've been reading the battery sensor example script on the MySensors page http://www.mysensors.org/build/battery I want to put a few battery sensors around my house, and plan to use 9V batteries and probably a some AA/AAA sensors as well. The example on the page above mentions the use of the 3.3v mini and 2AA; does the same voltage divider apply to an Arduino Nano and the batteries I intend to use, or should it be adjusted?

Hi! The nano is 5v and accepts (limits) 6-20 V on the raw pin.
You could power the nano through the raw pin and use a voltage regulator for the radio if you want to use 9v batteries. The battery should be measured 100% when 9v and 0% when 6V i guess.

Maybe some hints here.
