Basic Idea:
Creating simple things is always good for a learner like me.
I created a simple Led display using 8051. Total pin used is 2 ,for character
generation. So, as we can see we can use 2051 for this kind of display. One set
of pin is to scan through row and another set of pin to handle LED (On/Off) by column.
The basic catch behind this circuit is serial data transmission, which makes
this project cost effective.
