LED Display multiplexing simply means turning on one led for a short period of time and doing this repeatedly for each LED. Your eye reacts slowly to changes in light intensity so that if a light is turned on and off quickly enough then it does not notice that the light is off. Basically your eye remembers a light pulse for a short time.
The approximate time is 20ms so if the light is turned on at a frequency >50Hz (1/20ms) then your eye will not notice any flicker at all. The rest of the codes are in http://blog.duklabs.com/index.php/arduino-8x8-led-matrix/

Yes. For Pete's sake! Ipalibing na natin si Ex-Pres Marcos. Grabe puro formaline na yung body nya. He deserves to rest (as in rest under the ground) eternally in a proper place -- not in a museum. He may have done numbers of terrible things, like pagpapadukot ng mga taong tumutuligsa sa gobyerno tapos ito-torture. But come to think of it, marami din naman syang nagawa para itaas ang lebel ng ating bansa! NLEX, SLEX and CAVITEX, were built during his term. Siguro, natubunan nalang ng masasamang karanasan dulot ng Martial Law Declaration yung mga Achievements and Projects nya.
