Hello Everyone,
Im trying to build a 3 month countdown timer alarm in the smallest miniature form there possibly is using the smallest electronic components. Trying to use the smallest battery like a watch battery or smaller, I would like the timer countdown to start right after I apply power to the battery then sound a buzzer after the countdown has been completed. Id like the buzzer to be the smallest and very low consumption.
If anyone can help me supply me a schematic diagram and the parts list it would be great that way I can go ahead and build it and test it.
Thank You All.
