Description
The number module displays information about the signal its receiving from your other modules. It has two modes: in value mode, it displays a number from 0 to 99 on its LED display, where 0 is totally off, and 99 is all the way on. In volts mode, it displays the actual voltage on the signal pin, from 0.0 to 5.0 volts. It takes the same signal it receives and sends it out to the next module.
