Ahhh i Understand now, that made a lot of sans ! thanks a lot !
last question ( quite banal indeed ! ) .. for the push buttons to set the hours and minuts, i am plannning to hook them to the analog pin 0 ( PC0 ) and 5 ( PC5 ) of the arduino, where the one leg is connected to the 5v through a resistor and the other leg is grounded.
i am also planning to use a RTC to get an accurate time, instead of the internal clock, using the schematic in the picture
is it the right way to do it ?
