The number module gives you a look into how your modules work:
it displays information about the signal it’s receiving from your other
modules. It has two modes: in “value” mode, it displays a number
from 0 to 99 based on the input. In “volts” mode, it displays the
actual voltage it is receiving, from 0.0 to 5.0 volts.
