5. 1. Introduction
This project can be used for Advertising or for providing information at various places like
shops, government offices, hospitals, railway stations. The Rolling display is prepared using
Matrix LEDs which means LEDs are arranged in a pattern consisting of 5 columns and 7 rows.
A matrix of LEDs contribute to a single character. Here we have used 5 characters which means
5 matrices. The actual physical dimension of single matrix is 60 mm by 60 mm, so dimensions
of complete display is 360 mm by 60 mm. WI-FI is used for receiving data from mobile. The
message received from mobile is displayed on the Rolling display. WI-FI technology is used
so that user can change the message from a remote location. User doesn’t have to go near the
rolling display to change the message.
Objective: To design a WI-FI based controlled Electronic Notice Board.
2. Literature Survey
We know the importance of notice boards in public places like railway stations, bus stations
and airports. But changing notices day-to-day is a difficult task. This article explains you how
to design a Wireless Electronic Notice Board using ESP8266 WI-FI Module technology. The
project displays the data on LCD whatever we sent from the mobile. There are many wireless
communication technologies like Bluetooth, RF Communication, ZigBee, etc. but ESP8266
WI-FI Module Technology based communication allows long range, reliable and secure
communication. The Wireless Electronic Notice Board using ESP8266 WI-FI Module project,
as the name suggests, is built around ESP8266 WI-FI Module Technology as mobile phones
(that communicate through ESP8266 WI-FI Module Technology) have become very abundant,
cheap and easy to use.

4. Block Diagram Description
It mainly consist of following blocks
4.1. Matrix LEDs: We have to display characters in the messages, for this purpose we are
going to use of LEDs. A single matrix consists of 5 columns and 7 rows. The actual physical
dimension of single matrix is 60 mm by 60 mm.
4.2. Control Unit: This unit is used to select the matrices sequentially, control unit gets input
from Arduino Uno and then gives output to individual matrix. Only one matrix is selected at a
time so as to display a character.
7. 4.3. Arduino Uno: The Arduino Uno is the core element of this project, The Arduino Uno is
a microcontroller board based on the ATmega328. It has 14 digital input/output pins (of which
6 can be used as PWM outputs), 6 analog inputs, a 16 MHz ceramic resonator, a USB
connection, a power jack, an ICSP header, and a reset button. It contains everything needed to
support the microcontroller; simply connect it to a computer with a USB cable or power it with
an AC-to-DC adapter or battery to get started.
4.4. EEPROM: We are going to use EEPROM memory, it is Electrically Erasable
Programmable
Read only Memory. It stores the data even if power supply is disconnected. This is used to store
the characters which have to be displayed on the Matrix display.
4.5. ESP8266 WI-FI MODULE: We are going to use ESP8266 Wi-Fi Module interfacing,
the message to be displayed on Matrix LEDs will be received from ESP8266 Wi-Fi Module.
5. Components for Electronic Notice Board using ESP8266 WI-FI Module
Hardware Requirements
• Arduino Uno Atmega 328
• Arduino Uno Programming board (Programmer with cable)
• Arduino Uno Development Board
• ESP8266 Wi-Fi Module
• A smartphone or PC
• Matrix LED Display & we can take LED or LCD Screen
• 10 KΩ Potentiometer
8. • Connecting wires
• Power Supply
Software Requirements
• CADSOFT EAGLE is the software used for designing of the PCB
• Arduino Software for program Atmega 328
6. Methods and Designing Techniques
The above circuit of the Wireless Electronic Notice Board using ESP8266 WI-FI MODULE of
Arduino Uno, ESP8266 WI-FI MODULE (Modem) and LED. Here, the LED is used to display
message and is used in 8 – bit mode. Means, we need 8 data lines to display the data. The data
lines of the LED Display are connected to PORT1 Pins. The control pins RS, RW, and E pins
are connected to P3.6, GND and P3.7 pins respectively.
The ESP8266 WI-FI Module is directly connected to the Arduino Uno as the logic levels of
both the ESP8266 WI-FI MODULE Modem and Arduino Uno are already matched in the
ESP8266 WI-FI Module Board. If there is no level converter on the board, then we need to use
MAX232 level converter as a mediator between Controller and ESP8266 WI-FI MODULE to
transfer the data.
In order to communicate with the ESP8266 WI-FI MODULE Modem, we need to send some
AT commands using serial communication (UART protocol). Here, ESP8266 WI-FI MODULE
is used. This module requires 9600 baud rate.

8. Applications
• In School, Colleges and Universities to display students results, events and imported
notices.
• In Hotels to display welcome notes and costs of all items.
• In Banks to display special offers, new plans and various services of them.
• In Airports to display arrival and departure timings of planes, and special attention
messages.
• In Railway stations to display platform numbers, arrival and departure timings of trains,
and special attention messages.
10. 9. Advantages
• The message to be displayed can be changed as often we need, by using PC or Cell
Phones.
• The cable is not necessary in between transmitter and receiver.
• So the receiver can be placed anywhere in the particular range from the transmitter.
• Capital alphabets (A-Z), Small alphabets (a-z), numbers (0-9) and special character can
be displayed.
• A lot of interaction and information sharing.
10. LIMITATION
• Display unit must have the network to receive the message wirelessly.
• As there is no password any one can send the message to display.
