I want to include a battery backup for my alarm clock project. However I can't find any circuits for this, nor can I figure out quite how to do it. It sounds simple... until I try to figure it out.
I intend to use a standard 9v alkaline battery to run the chips and power the alarm circuit (if needed) until mains power returns.
Thanks.
