The input voltage range is 0 to 5 v, and the output number range is 0
to 255. The relationship is linear, so 2.5v = 128 (for example)

to convert from the output # to the voltage, it would be
5v x (output # / 255)
so 47 is about 0.92 volts.

| Hello! Would anybody please send me a mail letting me to know the relationship between the output of ananlog() function and the voltage ?
