 Demonstration sketch for Adafruit i2c/SPI LCD backpack
 using 74HC595 SPI expander
 ( http://www.ladyada.net/products/i2cspilcdbackpack/index.html )

 This sketch prints "Hello World!" to the LCD
 and shows the time.
 
  The circuit:
 * 5V to Arduino 5V pin
 * GND to Arduino GND pin
 * CLK to Digital 2
 * DAT to Digital 3
 * LAT to Digital 4
*/


// include the library code:
#include "Wire.h"
#include "Adafruit_LiquidCrystal.h"

// Connect via SPI. Data pin is #3, Clock is #2 and Latch is #4
// Adafruit_LiquidCrystal lcd(3, 2, 4);
Adafruit_LiquidCrystal lcd(11, 13, 10);   // Changed by Bohn to match CowPi

void setup() {
  // set up the LCD's number of rows and columns: 
  lcd.begin(16, 2);
  // Print a message to the LCD.
  lcd.print("hello, world!");
}

void loop() {
  // set the cursor to column 0, line 1
  // (note: line 1 is the second row, since counting begins with 0):
  lcd.setCursor(0, 1);
  // print the number of seconds since reset:
  lcd.print(millis()/1000);

  lcd.setBacklight(HIGH);
  delay(500);
  lcd.setBacklight(LOW);
  delay(500);
