now i using the voltage divider rule and the resister i will 18ohm and the test cricuit i will post at below and i got hear that D1820 that is digital temperature sensor...but i duno how to use it...i no use that before....and now how to make the sensor become stable.......
on the pict the blue colour is my temperature sensor....
and the resistor value is 18ohm
and the red colour wire i connet to ADC on port A.0
and the whole the circuit i also post at here ad...i hope u can help me....
if really want to change the sensor D1820 the circuit how it look like and where can get it and the programe need to write again or not need...!
