Thanks, Don

here is the sketch from LadyAda - only change was the sequence of the pin #s

#include "Adafruit_MAX31855.h"
#include <LiquidCrystal.h>

int thermoCLK = 3;
int thermoCS = 4;
int thermoDO = 5;

// Initialize the Thermocouple
Adafruit_MAX31855 thermocouple(thermoCLK, thermoCS, thermoDO);
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(7, 8, 9, 10, 11, 12);

  
void setup() {
  Serial.begin(9600);
  // set up the LCD's number of columns and rows: 
  lcd.begin(16, 2);
  
  lcd.print("MAX31855 test");
  // wait for MAX chip to stabilize
  delay(500);
}

void loop() {
  // basic readout test, just print the current temp
   lcd.setCursor(0, 0);
   lcd.print("Int. Temp = ");
   lcd.println(thermocouple.readInternal());
   lcd.print("  "); 
     
   double c = thermocouple.readCelsius();
   lcd.setCursor(0, 1);
   if (isnan(c)) 
   {
     lcd.print("T/C Problem");
   } 
   else 
   {
     lcd.print("C = "); 
     lcd.print(c);
     lcd.print("  "); 
   }
 
   delay(1000);
}

Here are some photos but as you said, it must be hooked up to the UNO properly for "Hello World!" to work

The pinout for the LCD is 11-RS to UNO pin 11, 9-EN to UNO pin 12, 4-D4 to UNO pin 7, 3-D5 to UNO pin 8, 2-D6 to UNO pin 9 and 1-DB7 to UNO pin 10

Hope this gives you the information you need
