Assistance - lights / aux switches on UTV via iPad or Tablet

Hey all you SFE guru’s! I’m a newbie with a background is computers and basic electronics. With all the great apps that are now available for off road trail maps and all, I’m tired of looking at a small screen. I plan to mount a iPad or Android tablet inside my polaris rzr utv for mapping/gps/etc.

What I’m wondering is what would be the difficulty / path to building a device that could connect say 12 or so on / off switches for lights and accessories via my iPad / android or even a microsoft tablet pc? It could be direct wire or blutooth.

Thoughts or I’m crazy?:slight_smile:

Thank you!
