// include the library code:
#include
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(15, 14, 13, 12, 11, 6, 4, 3, 2, 1);
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);
