Introduction

In this project I am going to demonstrate how to display Potentiometer Input Value on LCD 16x2.

This project will involve using a little a bit of code and a very simple circuit that’s great for beginners.

The video further down this page will go through all the steps to completing this very cool Arduino DIY Potentiometer Value Display on LCD 16x2.

This project aims to show Potentiometer Value on LCD. This will serve as a base to build more amazing projects.

In every electronic project we must think about what the input and output devices to use, the potentiometer is one of the best known and cheapest, we use the analog input reading due to the interaction of the project with the environment, along with this We must give importance to the output or presentation of the value

Working on Basics

The LCD have been powered by Arduino UNO (Board). It contains a code which uploaded to the board. And once it simulated you can see Potentiometer Input Value by rotating it and LCD.

We will use an LCD 16×2 display in this tutorial and we will need one potentiometer, to get readings.

The Arduino uses an analog pin to read the sensor values. So the potentiometer we want to read will connect it to the analog pin of the Arduino.

Refer to this video there is full instruction CLICK HERE

Usage

There is Multiple Usage of this Product:-

You can came to know how to interface with potentiometer

If you are a beginner than this is very useful for them to get interface with lcd

You can check the value of potentiometer on LCD

Code

Code

#include <LiquidCrystal.h>
int sensorValue = 0;

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(11, 10, 5, 4, 3, 2);

void setup() 
{
  pinMode(A0, INPUT);
  // set up the LCD's number of columns and rows:
  lcd.begin(16, 2);
  Serial.begin(9600);
  lcd.begin(16,2);
  lcd.print("Starting System");
    delay(1000);
    lcd.clear();
    lcd.print("System On");
    delay(1500);  
  
lcd.clear();

}

void loop() 
{
lcd.setCursor(0,0);
lcd.print("  DIY Inventor");
    

  sensorValue = analogRead(A0);
  Serial.println(sensorValue);

lcd.setCursor(0,1);
lcd.print(sensorValue);
lcd.setCursor(4,1);
lcd.print("Sensor Value");
  

  delay(500);
  lcd.clear();
}
