I dont know if I am about to embarc on the arduino-trip or not so I place my question to the allmighty community!
I have 3 pushbuttons thats should operate 3 relays. Every push of a button should activate or deactivate its dedicated relay. But I also want a timer to start when the relay is activated, after ~60 seconds the relay should be deactivated
Is this doable with arduino and can you guys hint me in the right direction about hardware and program examples?.
I got a UNO r3 from a friend, is that enought or do I need some other hardware? (relays, buttons, etc of course!!)
