+  LiquidCrystal Library - Hello World
+
+ Demonstrates the use a 16x2 LCD display.  The LiquidCrystal
+ library works with all LCD displays that are compatible with the
+ Hitachi HD44780 driver. There are many of them out there, and you
+ can usually tell them by the 16-pin interface.
+
+ This sketch prints "Hello World!" to the LCD
+ and shows the time.
+
+  The circuit:
+ * LCD RS pin to digital pin 12
+ * LCD Enable pin to digital pin 11
+ * LCD D4 pin to digital pin 5
+ * LCD D5 pin to digital pin 4
+ * LCD D6 pin to digital pin 3
+ * LCD D7 pin to digital pin 2
+ * LCD R/W pin to ground
+ * LCD VSS pin to ground
+ * LCD VCC pin to 5V
+ * 10K resistor:
+ * ends to +5V and ground
+ * wiper to LCD VO pin (pin 3)
+*/
+
+// include the library code:
+#include <LiquidCrystal.h>
+
+// initialize the library by associating any needed LCD interface pin
+// with the arduino pin number it is connected to
+const int rs = 12, en = 11, d4 = 5, d5 = 4, d6 = 3, d7 = 2;
+LiquidCrystal lcd(rs, en, d4, d5, d6, d7);
+
+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() {
+    // Turn off the blinking cursor:
+    lcd.setCursor(0, 1);
+    lcd.noBlink();
+    delay(3000);
