I would like to make a kind of countdown timer - preferably with a large 7-segment display, and a buzzer.
I am going to use it when I'm brewing beer, and would like to be able to program it just once, before I start the boil. I want to enter all the times before I start the boil, and then just hit a button when the boil start. And the alarm wil buzz (a certain signal?) when it's time to add the first hops, second hops (and so on) and finally at the end, when the boil is over.
Will this be possible for a beginner? Anyone know of a project similar, that I can just modify to my needs? I have tried googling, but I can't find anything other than automated Arduino Brewing computers and stuff like that.
I have a UNO available, in addition to a couple of Pro Micros and Pro Minis. I also have a 2x16 LCD laying around, but for the timer clock, I would really like a large 7-segment or something - so I can mount it at a highly visible spot on my garage wall.
Any ideas where I should head to get into this project?
