Abstract

The Design of a Microcontroller Based Electronic Billboard using GSM was developed with two ATMAGE328P microcontrollers from Atmel. The microcontrollers provide all the functionality of the display with wireless control. The Display is obtained on a 16X36 Light Emitting Diode (LED) module display. A desired text message from a mobile phone is sent via a Global System for Mobile Communication (GSM) to the GSM module located at the receiving end of the system, the message is then stored in the Electrically Erasable Programmable Read Only Memory (EEPROM). The GSM module is connected through Integrated Circuit (74HC595 IC) to the ATMEGA328P microcontroller. The message that was stored in the EEPROM was then displayed on the billboard. This hardware uses regulated 5V power supply. A three-terminal LM7805 is employed for regulation of the voltage. A full wave bridge rectifier was used to rectify the AC output of the secondary of 230/12V step down transformer. The system was tested and recorded huge success.
