I'm trying to learn about different electronic timers for a project I have (and learn about electronics in general). I want to run a low-power LED lamp (~3V, 250 mA) that is always on, except that it shuts off every night for 10 or 12 hours (user adjustable).
Q1: Can the 555 timer do delays for that length of time? If I understand correctly, they use resistors to determine the time delay, usually of seconds, and this length of time might require too many/big resistors?
Q2: If so, any suggestions for a component that would allow user to toggle between different modes of 10 hour delay vs. 12 hour delay?
Thanks, any suggestions much appreciated!
