Hi guys. I have purchase this sheld for Arduino: https://www.olimex.com/Products/Duino/Shields/SHIELD-LCD16x2/open-source-hardware
and then I purchased a realtime clock module: DS1307 RTC
I need to create a sort of alarm clock which can be programmed with 4 events. (I want to connect the 4 programs in 4 relays, for my AQUARIUM, that I have already prepared).
So, alarm clock, as I've seen do. The only difference is that you must have more programs. Each connected to a different channels, 4 programs might be enough.
I would understand if there is something already done.
Someone can give me a tip to get started?
