Hello well it's just a idea i have for a future project to have a dual redundant arduino to share the same sensors yeah i know its a little over kill lol. but no clever scheme there. <...>
Rats! Someone else got in first while I was watching the fireworks! And went to bed soon after.Yes - clearly if you want redundancy, you must use two sensors as well as two Pro Minis.
You could always buffer the sensor outputs with a unity gain op-amp. that'd give you a crude form of isolation (obviously need to check any impedance requirements of the source).
