LCD 16×2

This project is in process of completion.  I will finish the code with shift register

I wanted to get a 10K POT working with the LED 16×2 I found in the parts box.  It might come in handy later on for displaying reading.  I put an SN74HC595 Shift register on it.  It was not easy to wire up.  I lost use of LED 13 for the I2C counter.   I know somewhere in one of the storage bins, I have I2C LED displays: 16×2 and 16×4.   I will be replacing this setup with it. 

#include < SPI.h >

#include < LiquidCrystal.h >
//remove the spaces above
 
// Initialize the LCD screen using the latch pin
LiquidCrystal lcd(5);
 
void setup() {
  // set up the LCD's number of columns and rows:
  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);
}
