Wire interference with many inputs

[PaulRB]

@loveofsparks

Does it make a difference whether i pull registers inputa to high or low in terms of interference?

No. Not in terms of interference. But the value of those resistors might make a difference. Too high, and interference can become a problem.

@loveofsparks

Will my wire cause button presses not to be registered, e.g voltage losses

No. The current should be very low, so any voltage drop would also be very low.
