Looong wires for digital input lines
-
I have long (~10m) wires connected to Arduino Pro 3.3V ports. All of them used with just debouncers, so I connect these wires with GND to switch something.
Shall I do something special to decrease noise or any other potential problems?

@Alexander-Ivanov I use long wires for buttons too and have no problem so far. I use an EIB wire 4x0.8 with a length of about 40 meters for this purpose.
