thanx for your responses "SubR" and "8-bit".
yeah ... i almost forgot the time shift..
i live in Tehran but ,our clock zones
only have 2.5 Hour difference wich is not really much to be considered. the matter of fact, in my country, all bloggers are almost night owls and they mostly write at night, not days... to proove this just take a look at the time of my first post.
by the way,the use of a triple input AND Gate wont be possible because the 4026 output current cant trigger the AND gates. even i tried Danyk's 4-diode methode but it failed...and i dont know why? can any one explain the idea behind this method?
has any one ever tried?
i should say i dont have access to youtube .
im in hurry , because i must finish ASAP.
and this is the reason . i desprately need to finish.
THANX ....THANX..... THANX
