@Paulnaude01

It is my interest to explore your problem a little bit more for which I would like to request you to give answer to the following questions:

  1. All codes of your original program (without float) with code tags. This is to see that you have or have not really declared data type for your variable temperature.

  2. Which Arduino (UNO, NANO, DUE, MEGA) have you used with LM35 sensor?

  3. Which analog channel have you used to acquire analog signal from LM35?

  4. What is the reference voltage (DEFAULT = 5V; INTERNAL = 1.1V, EXTERNAL = AREF) that you have used for the ADC?

Thanks.
