Wiring Diagram

I did not have enough orange wire so used blue instead, however I made the 4 wires for data orange in the sketch.

Code

The Software part

Arduino
The software will communicate with the LCD and the analog pins of the Arduino. Because we use the LiquidCrystal library, we don't have to communicate with the digital pins.
// include the library code:
#include <LiquidCrystal.h>

// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7,8,9,10,11,12);

int potPin1 = A1;
int potPin2 = A2;

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

pinMode(potPin1, INPUT);
pinMode(potPin2, INPUT);
}

void loop()
{
lcd.setCursor(0,0); // Sets the cursor to col 0 and row 0
lcd.print("SensorVal1: "); // Prints Sensor Val: to LCD
lcd.print(analogRead(potPin1)); // Prints value on Potpin1 to LCD
lcd.setCursor(0,1); // Sets the cursor to col 1 and row 0
lcd.print("SensorVal2: "); // Prints Sensor Val: to LCD
lcd.print(analogRead(potPin2)); // Prints value on Potpin1 to LCD
}
