*** NOTE: It is a good idea not to exceed the 5 volt limit of these lines.

The information read from one of these lines will be a number from 0 to

1023. That means that with 0 volts applied to the pin, the number read will

be 0; with 2.5 volts (or half of 5 volts) applied, the number read will be

half of the maximum or 512; with a full 5 volts applied, the number will

be 1023 or very near it. Once this number is known, your can convert it to

temperature, weight, sound levels, color or whatever your connected sensor

was designed to measure. Your sensor will come with the information you

will need to make the conversion.
