Battery backup might be a better use of resources.
Yes that is what I was thinking. I planned for the RTC to have it's own battery.crane said:Are you going to have it log with time stamps ...andy pick up where it left off? If you want to do this then you will still need battery backup for the RTC itself to not loose track of time.
I'm thinking that the battery backup would be for the Arduino and possibly the RTC to keep track of where the process stopped, how long it's off, and then allow an intelligent restart.crane said:you will still need power to turn on your pumps, valves and heating elements..
crane said:To handle a power loss I would think it would be more effective and easier to code by allowing you to restart a brew profile at step number x rather than intelligently trying to pick up where it left off.

jpalarchio,
How do you use the RTC?
SMc0724 said:How would that work? Just log the events, then what happens at restart?
