Okay, I'm being cheap again an want to use the temp probe off a broken electronic thermometer (or a temp controller out of a computer psu) but I cant figure out how to get a reading off them... I was assuming it was a resistance that changed with temperature so hooked it to +3 and A0 & tried to read it but got a fluctuating reading so its not that simple.
Anyone have a link or advice as to how to read the value off these salvaged devices?
Thanks in advance...
