Howitworks

7x5 is a standard resolution for displaying ASCII characters, so 7x10 click is essentially a dual

character display capable of showing letters in more readable typefaces compared to a 14-

segment display.

The dot matrix can also show scrolling text, thus fitting longer messages in small space. The pair

of 8-bit SIPO shift registers drive the display. The current amplification necessary for driving the

LEDs is performed by a Darlington Transistor array while a Johnson counter performs the

necessary LED multiplex.
