Re: Driver Station Digital Input

Use a 10 k resistor to tie the signal to +5 volts, rather than directly to signal. In theory it shouldn't matter but the resistor is the common industry standard way, because it ensures that errors won't cause damage. You can even connect the +5 to signal through the 10 k resistor and just short the signal to ground with the switch...with impunity!
