 Interfacing the Keyboard to 8051 microcontroller
The key board here we are interfacing is a matrix keyboard.
This key board is designed with a particular rows and columns.
These rows and columns are connected to the microcontroller through its ports of the micro controller 8051.
We normally use 8*8 matrix key board.
