Hello. I own an arduino nano and I have a problem with my A/D converter. I use external reference which is 3.3V and I'm reading data from an accelerometer. When it is in horizontal position, the x axis gives an output of 1.66V (measured with a voltometer) and that means that I should get a value o…

Is the A/D linear?
