Hi! I wanted to design a sunlight readable clock with a long battery life. And hopefully a choice of easily replaceable AA batteries.
I guess the top choice would be a 7-segment led display for brightness and a PIC of some sort.
I would need a switch to turn it off and on.
What other choices should I make to make sure it runs off a AA battery and that its sunlight readable and has a battery life as long as possible ?
