I have a school project and I can't make it work correctly. I used diagram and code from this page http://www.eprlabs.com/2011/11/89s52-based-temperature-sensor-using-adc/. I added reset button, relay and ISP for programming. Now, the program shows values from 011 to 014 at room temperature (about 24 degrees in Celsius). Can anyone help me with writing the code, so it would work correctly? In the code I'm using right now, the relay isn't used at all.
Picture of my diagram is here
**broken link removed**
Names of elements in diagram are not correct, because Eagle didn't have correct items and I used items, that had same size/number of legs/function for printig on board. I also added capacitor before and after 7805 voltage regulator.
I really need working code for this (code should activate realy at certain temperature).
Looking forward to solutions!
