How To Display Message On LCD Using Serial Monitor Of Ardunio

In this article we are going to link hardware and software of Arduino with the LCD. We are going to display typed Message on LCD 16/2 display using Serial Monitor, see where you can gather information on how to work with Serrial Monitor, and how to work with 16/2 LCD display and also gain the pleasure of technical knowledge.


  1. LCD 16/2 display
  2. Arduino Software
  3. Arduino UNO R3
  4. Connecting wires
  5. Bread Board
  6. Data Cable

Steps to follow

Step 1

Open Arduino software. I have the latest version of Arduino software. You can download Arduino software from official website of Arduino.


Step 2

Include the Header file for liquid crystal. Overview on 16/2 LCD display is given in my Article “Working with 16/2 LCD display.”   Tools>> Include Library>> Liquid crystal.


Step 3

Write the given codings in the Arduino Software…


Step 4 

Compile and Upload the code to the Arduino.


Step 5

Follow the circuit diagram for circuit connection. You can also change the pins of the Arduino.

Step 6

Open Serial Monitor of your Arduino Software.


Step 7

Enter the command which you want to display in the 16/2 LCD display.


Step 8

Click OK or SEND to send option from the Serial Monitor to the Serial Monitor.


Step 9

The .hex file of Arduino will search for the Arduino board if Connected to the Laptop or system. If device is found it will boot and command  Aduino and Arduino will command LCD to display.

Step 10

The output will be displayed on your 16/2 LCD display. You can change your output as per your command as per your requirements.



In this article we learned how to work on Serial monitor of Arduino and also work with 16/2 LCD display to display a message.
