exit status error fix

pls fix all the errors .I want to upload the code to Arduino nano

flowmeter and volume measurement.txt (1012 Bytes)

Please follow the advice on posting a programming question given in Read this before posting a programming question

In particular note the advice to Auto format code in the IDE and to use code tags when posting code here

OP's code

#include <LiquidCrystal.h>
LiquidCrystal lcd(7, 6, 5, 4, 3, 2);
int X;
int Y;
float TIME = 0;
float FREQUENCY = 0;
float WATER = 0;
float TOTAL = 0;
float LS = 0;
const int input = A0;
void setup()
{
Serial.begin(9600);
lcd.begin(16, 2);
lcd.clear();
lcd.setCursor(0,0);
lcd.print(“Water Flow Meter”);
lcd.setCursor(0,1);
lcd.print(“****************”);
delay(2000);
pinMode(input,INPUT);
}
void loop()
{
X = pulseIn(input, HIGH);
Y = pulseIn(input, LOW);
TIME = X + Y;
FREQUENCY = 1000000/TIME;
WATER = FREQUENCY/7.5;
LS = WATER/60;
if(FREQUENCY >= 0)
{
if(isinf(FREQUENCY))
{
lcd.clear();
lcd.setCursor(0,0);
lcd.print(“VOL. :0.00”);
lcd.setCursor(0,1);
lcd.print(“TOTAL:”);
lcd.print( TOTAL);
lcd.print(” L”);
}
else
{
TOTAL = TOTAL + LS;
Serial.println(FREQUENCY);
lcd.clear();
lcd.setCursor(0,0);
lcd.print(“VOL.: “);
lcd.print(WATER);
lcd.print(” L/M”);
lcd.setCursor(0,1);
lcd.print(“TOTAL:”);
lcd.print( TOTAL);
lcd.print(” L”);
}
}
delay(1000);
}

Did you by any chance copy the code from a Website ?

Copy it back to the IDE from post #2 and the Unicode characters that it contains should be removed
