Introduction
In our day-to-day life we have seen many digital sign boards and these digital LED displays are commonly
visible as advertising strategies, information display mechanism in public places, safety instruction
mechanisms, commercial aspect to display data and in certain sectors of medicine and science. In this project
I mainly focus on the information display mechanism in educational institutes and production floors in
manufacturing industry. The most commonly used digital sign boards are the wired LED displays and the pre-
programmed memory chip installed LED displays. It has a major disadvantage when it comes to changing the
display program.
Therefore, I proposed a wireless mechanism for change the data that could be displayed on the sign board. It
is a Bluetooth controlled LED sign board display based on Arduino micro controller using set of 8X8 LED dot
matrix display with MAX7219 microcontroller. For the Bluetooth feature in this project, I’ve used a PC-06
Bluetooth module and android Bluetooth application that gives the display board accessibly through any digital
device that has Bluetooth facility developed through the Thunkable.com online mobile application
development website. It makes the switching process from several devices very fast and accurately.
Literature review
A considerable amount of theories and experimental researches are published on LED displays with wireless
Communication. As per the International Journal of Computer Applications (0975 – 8887) on Design and
Development of GSM based Multiple LED Display Boards in June 2013 has suggested a solution to overcome
the drawbacks of previous text message moving display showcases using wired entries via computers,
keyboard or remote-control entry (small distance).
The solution was presented as a connection of both wireless technology with LED Display Boards which are
formalized in terms of design and integration of the hardware and software with AT89S52 microcontroller,
GSM module, LCD, moving LED display. (Kamboj, R. et. al 2013)
“WIRELESS NOTICE BOARD Our Real-Time Solution” presented at the National Conference on Recent
Trends in Engineering & Technology, May13-14 (2011) is also based on the GSM technology. (Dalwadi, D.
C et. al 2011)
