My scoreboard project uses some mechanical switches for the user to adjust the score. I want to connect the switches as one bundle to the arduino board through a RJ45 plug and jack. The problem is, the breakout board for the jack puts 8 pins all in a row. I need to send +5v and ground to the switches. I can probably connect a ground easily enough from the battery, but for the +5, I was hoping to send it up that same bundle. The only way I can think of doing it right now would be to to set one of the digital pins to output high and leave it that way. I can send that up to the switches and as the user manipulates the switches, it would effectively send that +5 back down to a different pin. Therefore I would have two digital pins connected together when the switch is pressed.
I know the arduino has a +5 v pin that I could normally use, but my breakout board for my RJ45 jack will sit on top of 8 digital pins. I guess I could cut one of the pins and route the +5 over in its place, which wouldn't be awful, but I was wondering if there was a better way.
