I want to use a push button for on-off, another push button, a small buzzer-the one that we have in wrist-watches and a LCD display similar to that of a digital wrist-watch. Which is the best micro-controller that I can use for this?
I want it to be operated with button cells or the small pencil cell. Which cell would be a better option? (It should last upto 8-10 months, minimum 6 months)
