I need help with a very small and very easy project. Or so I think
I need to build a flashing LED that will gradually lessen the time between flashes until eventually reaching the point of constant on, and at that time turn off. The time I'm aiming for is to take around 10-15 minutes to reach the off mode.
I'm not a complete newbie, as have taken several courses of electronics way back in high school. But as everything else I learned in school, isn't easy to remember these days.
I would like to keep the project small: small battery, 1 led, I'm assuming some chips may be in order, and need a reset button.
Also, if possible, and I need to have a way to either lengthen or shorten the time it take to reach its off mode. Not exact, or variable, but for example, allow it to adjust between 15 minutes and 30 minutes.
