RF message Tx & Rx with LCD.
1. Project summary:
A RF module is radio frequency transmission device which is capable of sending data in range of up to 20 meter.
In this tutorial
we are making a project which would transmit a message which is written in the
serial monitor of Arduino serial monitor would be transfer through RF
transmitter and then entered message can be seen on the LCD of receiver side of
RF receiver.
 |
Figure 1: RF message transmitter and receiver. |
In this project we are sending a text message on remote LCD screen with help of RF module thus we would need below described components.
Components: -
·
Two Arduino board.
·
Arduino software (IDE).
·
One RF module.
·
LCD 16x2.
·
Male to female Jumper
wire.
·
Bread board.
 |

3. Connection:
To make this project first we need to gather all the
component described above and make connect as shown below.
Connection on transmitter side: -
on the transmitter side there would be an Arduino with RF module transmitter.
By which message would be transmitted.

Note: - Don’t
forget to connect the variable resister between pin 1 and 3 of LCD for
controlling the brightness. If you are not using LCD Shield
4. Follow the following below steps to make project:
Step_1: Gather the
entire component and make connection as it is shown above. Than open up Arduino software and copy the code from below. file RF message TX RX with LCD TRANSMITTER and RF message TX RX
with LCD Receiver.
 |
Figure 4 Step_1 open up
Arduino files
|
Step_2: check a correct Arduino board and port in tool menu.
 |
Figure 5: Step_2 check right board and port. |
Step_3: -
after all doing above thin now burn the code to respective Arduino board and
detach the receiver part from laptop and place it anywhere in the room with
power supply.
 |

4. Result:
Now if you have done everything correctly than you can see correct result which are shown below and you project would work correctly.
In our project
we have two Arduino board in which one would be connected to your laptop and we
would be place anywhere in range of 0 to 20 meter. And then you can start
giving the message or data in serial monitor of Arduino software.
Transmitter side: -
This part of our
project would be get connect with our laptop because it would have serial data
from Serial monitor of Arduino Software, as shown below.
 |
Figure 7: Serial input
message from transmitter.
|
Receiver
side: -
This part is
receiver part which can be place anywhere in range of 0 to20 meter and all the
message data send from Serial monitor of Arduino from transmitter would be
received here on LCD display.
 |
Figure 8: result message
on LCD.
|
We would receive
whatever message sent from Serial transmitter on the LCD as we have send “ Hellow there MR ” from serial of Arduino and receiving the same message on LD.
5. Project Specification:
This project is wireless message
transmitting module which can be used to send message in half duplex way and
can used in many different projects also.
Project of RF message transmitter: -
·
An
office alarm for peon can be made with this project.
·
A
broad casting message system can be made.
·
A
notification board can be made with this. Where motivational and quote can be
share every day in at any place.
Many different things can be done with this simple project and you can
be more creative and further extent this project.
6. Arduino codes for project: - down load code from below link
Note: - don’t forget to add Virtual-Wire library in you Arduino software to make it work.
