Abstract
A low cost interface using 8051 micro-controller is
developed for data transition between IBM PS2 key board and
a display device to flash the alphabets, numerals and special
symbols directly to display by entering it from keyboard.
Further additional electronic circuit developed for wireless
data transmission between the two devices so that the displayed
information can be changed using the keyboard from a
distanced place. This helps to change the displayed
information where display is situated at a place that is not
easily accessible and facilitates the display operator
