Hi gentlemen,
my question is rather theoretical. I have project which has several parts. One of them is tracking irregulary changing (boolean - after A/D conversion, basically black/white) value.
The question is: Is there an elegant way to find out if value on sensor changed, other than periodically checking the pin value? I want the task to be as little as possible CPU time consuming.
Thanks for any proposals.
