Creating a minimal LED clock with Arduino for those with poor eyesight?
I have an idea for a clock that has four, rather dim LEDs flashing the time constantly. I need a LED for each place value: 10hr, 1hr, 10min, and a 1min LED, in different colors as necessary. I could also settle with a 5hr, 1hr, and 5min LED setup. As the clock runs, each place value would be blinked, pause a few seconds, and repeat the process. That way, just a quick count would let me know how much sleep time I have left.
Since I'm new to Arduino, it's beyond me for now. I'm looking for pointers as I haven't found any clock projects with such a simple display.
Has anyone seen any code snippets that could help me out?
What would be a good timer (GPS, WWVB, RTC, etc.)?
Where would be a good place to start?
I'm not looking for a finished product, obviously. I want to write the code myself. But I also would like some good building blocks to begin with to help me learn the process.
Any help would be appreciated!
