The projects are based on PIC chips. but it can easily be re-written to other languages, once u understand the basic workings of the AT keyboard.
For your project, the mcu need to be able to interface correctly with the keyboard. Buffered the key that u type n then u display them on ur matrix leds.

if he wanna keep data when the power is off must put eeprom or ....) 2-3 battery.
i haven't make that tipe of circuit, i have been read some in the net for this but... think is not so hard to make this
Re: how to use a keyboard to control the dot matrix display!
I have schematic and source code from google Schematic and source code here i Make experiment and i change ic with Atmega8535 why LCD no work,IF u can compiler for Atmega8535 share here i will experiment because my circuit is final and no conect to dotmatrix but conect LCD 2x16 only,i'm sorry my speak english is bad
