<b>[Product Information]</b><br>
<ul>
<li>A fun way to make a small display is to use an 8x8 matrix or a 4-digit 7-segment display</li>
<li>Matrices like these are 'multiplexed' - so to control 64 LEDs you need 16 pins.</li>
<li>The matrices use a driver chip that does all the heavy lifting for you</li>
<li>They have a built in clock so they multiplex the display</li>
