could this be put in a sub routine of some kind and be called from a main loop? would make me understand a bit better. I would then call this when temp have raised 5 degrees. of course the void setup() part should be moved to start of main loop (just a guess here)
code comes from here: http://www.open-electronics.org/tidigino-contest/
i have removed the DTMF part of the void loop() so i guess i could remove these 2 parts also from the void setup() and set pin numbers section:
const int stddtmf = 14;
const int q1dtmf = 72;
const int q2dtmf = 73;
const int q3dtmf = 74;
const int q4dtmf = 75;
pinMode(stddtmf, INPUT);
pinMode(q1dtmf, INPUT);
pinMode(q2dtmf, INPUT);
pinMode(q3dtmf, INPUT);
pinMode(q4dtmf, INPUT);
