In the description of the Tone library, it states:-
" Also, although it's the last timer to be allocated, timer 0 (which is used for millis() among other things) will be affected if used. "
Does this mean only while the tone is playing? or will my timing of my project which uses the millis for a countdown timer be compromised by merely calling up the tone library?
I want to sound a horn at the end of the countdown, so I dont need the timer then.. I just need confirmation
