Wherever I put this:
public static bool whyNot = false;
It gives an error. I would very much like to declare public variables inside methods... Is that not possible, or what am I doing wrong?
The error is:
exit status 1
expected primary-expression before 'public'
The full sketch:
/* This is the code for turning the HiFi System On or Off according to the audio input.
Written by Benedek Fodor.
The rights of included libraries belong to their respective owners.
This code is not public, I don't hold any responsibility for it.
Version 0.3, Complete rewrite. Paying more attention to the aesthetics, and "logicallity". Implementing Blynk library.
V 1.5 - different checking technique
V 1.6 - implementing new phisical interface, complete rebuild of harware.
V 1.7 - code rewrite, didn't work at all :D

I'm not done with it yetm that's why it doesn't have setup and loop.
