Arduino Code for Arduino Digital Voltmeter

c_cpp

this is the code for digital voltmeter

1#include<LiquidCrystal.h>
2LiquidCrystal lcd(12,11,5,4,3,2);
3int  analogPin=1;
4void setup()
5{
6  lcd.begin(16,2);
7}
8void loop()
9{
10  int v=analogRead(analogPin);
11  voltage=v/1023*5.0;
12  lcd.print("voltage=");
13  lcd.print(voltage);
14  
15}

#include<LiquidCrystal.h>
LiquidCrystal lcd(12,11,5,4,3,2);
int  analogPin=1;
void setup()
{
  lcd.begin(16,2);
}
void loop()
{
  int v=analogRead(analogPin);
  voltage=v/1023*5.0;
  lcd.print("voltage=");
  lcd.print(voltage);
  
}
