Arduino UNO LCD code to display data in loop
<p>I am new to Arduino. I want to display data read from the sensor on the LCD, first row fixed and 2nd row changing with sensor value. But I see first row for a while and then all garbage.</p>

<p>Here is the full code for reference:</p>

<pre><code>#include &lt;LiquidCrystal.h&gt;
char ch;
int Contrast=155;
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);

const int analogInPin1 = A0;  // Analog input pin that the potentiometer is attached to
const int analogInPin2 = A1;  // Analog input pin that the potentiometer is attached to
const int analogInPin3 = A2;  // Analog input pin that the potentiometer is attached to

int sensorValue1 = 0;        // value read from the pot
int outputValue1 = 0;        // value output to the PWM (analog out)

int sensorValue2 = 0;        // value read from the pot
int outputValue2 = 0;        // value output to the PWM (analog out)

int sensorValue3 = 0;        // value read from the pot
int outputValue3 = 0;        // value output to the PWM (analog out)

void setup() 
{
    Serial.begin(9600);

    analogWrite(6,Contrast); // setting contrast using code
    analogWrite(9,28836); // setting backlight led on

    // set up the LCD's number of columns and rows: 
    lcd.begin(16, 2);

    // Print a message to the LCD.
    lcd.setCursor(0,0);
    lcd.print(" CAR1 CAR2 CAR3 ");

    delay(200);
}

void loop() 
{
    // read the analog in value:
    sensorValue1 = analogRead(analogInPin1);
    // map it to the range of the analog out:
    outputValue1 = map(sensorValue1, 0, 1023, 0, 255);
    delay(250);
    sensorValue2 = analogRead(analogInPin2);
    // map it to the range of the analog out:
    outputValue2 = map(sensorValue2, 0, 1023, 0, 255);
    delay(250);  
    sensorValue3 = analogRead(analogInPin3);
    // map it to the range of the analog out:
    outputValue3 = map(sensorValue3, 0, 1023, 0, 255);
    delay(250);
    lcd.setCursor(0,1);

    lcd.print(outputValue1);
    lcd.print("  ");
    lcd.print(outputValue2);
    lcd.print("  ");
    lcd.print(outputValue3);
}
