Abstract:
For a long time, paper-based notice
boards have been widely used in the government
and private organizations, school areas to share
information among the customer. However, using
traditional (paper-based) techniques is a wastage of
paper and paper-ink and human power. As a result,
it is a time-consuming method and also it is not
cost-effective. Therefore, to mitigate the
aforementioned drawback, in this paper the design
and development of a smart wireless electronic
notice board are presented. The system is designed
using a GSM module, Bluetooth module, ardiuno
microcontroller, LCD, Buzzer, and LED. The
circuit diagram and its functionality has been
validated using the Proteus simulator. Based on the
distance, the user of the proposed system can select
one of the two approaches, are GSM modem-based
and Bluetooth module-based approaches. The
simulation and the hardware implementation of the
proposed system are successfully achieved. From
the result it has been realized that the proposed
system is only accessed by authenticated users, it
isa cost-effective system and very easy to handle.
Besides, the latency involved in using papers in
displaying notices is avoided. Therefore, the
proposed system has many upcoming applications,
as it can be set up at educational institutions and
organizations, public transport places like railways,
bus stations, airports, at the roadside for traffic
control, and advertisements purpose
