You don't have to set up analog pins. You are right about the float....Sorry. I'm a high school teacher that does simple vids for my students. I'm not a coder, but thanks to youtube I can pretend. Thanks for comment!

So I don't have to declare the probe as an input or output in the void setup()? Also, analogue value seems kind of useless since you can probably just do (analogread(l35pin) / 1023) so typecasting the float is really unnecessary.

Would it be okay if I declare analogValue as a float in the first place? Instead of declaring it as int and then casting it as float when calculating temperature

I am able to execute the program well. Thanks for the explanation. But i am facing a problem, the temperature is shown by negative value. The value is correct, but sign is negative. how to over come. I am doing a project on it, i would appreciate if you replay ASAP.

good day. i am doing a similar project and i would like to know why did you divide by 1023 and multiplied the temperature by 500.

I'm getting really high temperatures on every damn video. I tried everything. I just got my project kit brand new.

i i place my mobile phone over LM35, then would it give the correct temperature of my mobile phone?
