The blinking without the delay thingy.. thats multiplexing... Am I right?! I am right now trying to do a digital clock.. Now its working.. I mean I am able to multiplex two digit displays and make them count to 60 and then reset.. Still hav two other displays to attach to make up for the hours.. Next I wanna work with RF communication.. Too ambitious?! 
Or will I be going in the right direction?!
