Hi, This is a curiosity question; How long can one expect an Arduino based circuit to operate maintenance free? This is, of course, given any battery/power concerns.
What's the longest you have had a stand alone project operate glitch free?
The aspect I'm considering is as an art installation. A set it and forget it type of proposal. I know this is hard to judge from many perspectives, but barring an industrialized construction method, what kind of lifespan could one expect from a simple, well built, code running circuit?
Thanks for you thoughts, Gary
