If you don't know where to begin with a simple 7x21 matrix of LED's, then you should not be building it.

Here's a 7x21 LED display with programmable messages:  https://store.qkits.com/moreinfo.cfm/MML4

Whatever your application is, if you just need a message display then this will get you one for only $20.00.   
That's much cheaper than a month of design, debug and testing that you might need to do if you are unsure
of how to do this.
