/**
ButtonDecoder.
I was planning to make a r2R ladder network but I couldn't find any very accurate resitors here in Ecuador (no Señor, no tengo ... sigh)
so I bought some 5% resitors but they didn'0t work well enough. So this decoder sinply decoder the end value and this
it means only one button at a timn can be detected reliable.
