I have 10K Thermistor,arduino Board,3digit 7segment display so I make thermometer using this properties but I can't understand this logic code(sketch) please help me and give sketch of this thermometer............. :confused:

If you look at a sketch and don't understand it, how are we supposed to understand it even though we can't even see the sketch you are talking about?

How are you planning on wiring the Display to the Arduino? Without knowing that there is no way we can tell you how to write a sketch.
