Hello all, I'd like to design a circuit such that my Arduino can automatically switch to a backup battery if the standard power supply (a wall wart) fails, due to a power outage or circuit breaker tripping, etc. Any thoughts on this? I know the Duemilanove reference design has circuitry onboard to…
