Project Six – LCD Demonstration

Now it is time to demonstrate the LCD module and matching Grove units. With the LCD you can display data or messages within the two line, eight-character display. For this example, connect the wires from the following LCD sockets to the Grove Base Shield:

• right-bottom to D1/2;
• bottom-left to D3/4;
• bottom-right to D5/6;

Now upload the following Arduino sketch:

// Project Six - LCD demonstration
//

#include <LiquidCrystal.h>

LiquidCrystal lcd(1,2,3,4,5,6);

void setup()
{
  lcd.begin(8,2);
}

void loop()
{
  lcd.clear();
  lcd.setCursor(0,0);
  lcd.print("01234567");
  lcd.setCursor(0,1);
  lcd.print("ABCDEFGH");
  delay(65000);
}

The lcd.clear() functions blanks the LCD screen; lcd.setCursor() moves the cursor to (column, row); and lcd.print(“”); writes text to the cursor position on the LCD.
