Abstract :
- Scrolling led display boards are a common
sight today. Most of the things are made to be digital.
The usage of led scrolling display at super markets,
shopping malls, bus stands, railway stations and
educational institutes is becoming one of the effective
mode of communication for providing necessary
information to the people. But some of these units are
inflexible in terms of updating the message instantly. If
the person or the user wants to change the message it
needs to be done using a computer at the particular
location and hence the person needs to be present at the
location where the display board is placed. It means the
message cannot be updated from wherever or
whenever. Also the display board cannot be moved to
any other place because of complexity and delicate
wiring.
Keywords :
AT89C52 microcontroller, Wi-Fi module, 7×96 characters LED display, max232 serial interface.
