Control LCD Display with Arduino and Visual Basic

Control LCD display using Arduino and Visual Basic can be a useful project for displaying data or information.
To accomplish this, you will need to establish serial communication between the Arduino and Visual Basic.

Parts Required:

1. Arduino NANO
2. LCD – Alphanumeric-16X2 Characters (1)
3. resistor 220 ohm (1)
4. Potentiometer
5. Wires to connect it all together

#include <LiquidCrystal.h>

const int ledPin =  6;
int buttonState = 0;
String x;
String str;
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

void setup() {
pinMode(ledPin, OUTPUT);
Serial.begin(9600);
lcd.begin(16, 2);
digitalWrite(ledPin, HIGH);
}

void loop () {
if(Serial.available() > 0){
x = Serial.readString();
lcd.clear();
lcd.print(x);
if (x==“LED OFF”){
digitalWrite(ledPin, LOW);
}
else{
digitalWrite(ledPin, HIGH);
}
}
}
