Look at that pretty thing! I got it from our School Store over at NYC Resistor. It’s a four bit parallel LCD display, white on blue. Werry naice!

Right now it’s just serving as a data readout. Ultimately it will be used as the tweaking interface for the puppet suit, so that in the field we can avoid having to use a computer to make small changes.  We’ll be using the onboard EEPROM on the AVR to store those changes.

The unit is the ARDUINO LCD-shield V1.1 from

here’s a simplified version of the code I used:

#include <LiquidCrystal.h>  //include the library that does all the heavy lifting
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);   // initialize the library with the numbers of the interface pins
lcd.begin(16, 2); // set up the LCD's number of rows and columns: 
lcd.setCursor(0, 1); //put the cursor where we want it
lcd.print("I'd rather get a bike!!!"); // Print a message to the LCD

That’s it!
