I have the following problem ...
In my circuit, I'm selecting something external as a switch, actually about high & low.
Now I have only 0.3V low
And 0.9V high.
Measurable is the value reached but not the predetermined thresholds ... What can I do?
Do I need to artificially raise the voltage for High or can I get the Arduino to measure 0.9V as high?
Greetings and thanks
