I am confused!
The getting started manual says:
- the input range is 0 to 3.3 volts, but 5v tolerant. by default the read() gives 0…1023.
- using SetLinearScale(0, 3300) give real voltage.
However, Using A5 (Pin 19 on the physical board) my values are off. If I set the scale to (0,5000) I get correct results!! I check using a voltmeter.
I the manual wrong or am I doing something terribly wrong here?
