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. So only two ports of 8051 can be easily connected to the rows and columns of the key board. When ever a key is pressed, a row and a column gets shorted through...
