This LED moving message display is four feet in length and six inches in length. Horizontally their are 128 leds and vertically 16. It can show message in English language scrolling from right to left. The system is made using four P10 led display modules and ATmega8 as microcontroller. It has PS/2 keyboard interface that is used to enter message to the board. To enter text, keyboard is connected and Esc key is pressed, this brings the device into text entry mode. After this the whole message is typed using keyboard, at the end of message Enter key is pressed, this saves the message in internal EEPROM of the ATmega8. Now the keyboard can be removed.
