How to set up temperature input from sensor? (noob question :-)

[nadavmatalon]

Hi,

Thank you very much for sharing this great library!

Having looked at the library in general and example codes in particular, I have a noob question relating to my project.

I'd like to get the real-time temperature input of a hot plate from a PT-100 and use that as the input for the temperature PID control so as to get a stable temperature target on the hot plate (say, 180 degrees Celsius).

I already figured out how to get real-time temperature readings (in degrees Celsius) from the PT-100 every second, but the examples expect an "analogRead" input and I'm not sure how to go about matching/converting between the two values? (that is, the temp readings in degrees Celsius (int value) on the one hand, and the expected analog read input (0-255 or 0-1024?) on the other).

Should I simply use Arduino's "map" function and plug the result in the code instead of the expected "analogRead" value? or is there a better way of getting this done?

Any help would be very much appreciated and example code would be even better :-)

Thanks!
