I use a sensor lm35 for temp in A0
and a microswitch “f83161.3” in A3 but i have interference and more when a micro switch “open”.
example when i use only lm35 i have temp 24 celsius (this is right)
when i use in my code lm35 and microswitch i have temp 16 celsius.
when microswitch open then temp up 30 celsius.
What could be wrong
