I tried constructing this in a breadboard. All the 7 LEDs light up in normal temperature level. I tried adjusting the potentiometer but still, all of them light up. What is the problem?What value of thermistor should i use?I'm currently using 15k thermistor.
Please help me=)http://imgfreehost.com/out.php?i26540_22022009001.jpg
