Hello i'm Ben and new to the arduino forum only been dabbling with arduino, mainly following a tutorial here or there.
but i have a project in mind (early stages) i've broken it down in to sections and cant find an answer for this section i'm either asking the wrong way or missing something. so if any one can point me in the right direction it would be much appreciated.
so i would time to make a time clock, (and by that i mean a relay where by you could set times when it would switch on/off).
but i dont want a backup battery, or connected to a network and obviously if power was to fail i would want it to keep time when it came back on line.
any thoughts ??
