Dear All,
This Script is not completed, but I have a big problem since the value that I read on the pin A3 continue increasing over time.
(A3 is linked to a Preamplified Microphone).
On the contrary, if i Run a very simple script like the one below, the value does not increase.
Why?
Thank You
Marcello
