Arudino countdown timer? Answered
I'm looking to make a countdown timer for my local card shop for games of Magic (nerdy, I know). However, I think I jumped the gun, as I have no idea how to do this.
My plan is to us an arduino nano/barebone arduino as the brains to this, make my own 4 digit 7 segment display, and have give it a programmable time (nothing over 50 minutes) along with a start, stop, and reset button.
I've done quite a bit of looking, and have yet to find something that matches my needs or comes close to it so I can reverse engineer the code a bit. Any sort of help on this would be greatly appreciated!
Should also mention I'm a tad bit of a newbie to C. I know enough to know where i need to look for a good chunk of things, but thats for simple things like "make this LED blink according to these random inputs"
