* 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 with the numbers of the interface pins | |
LiquidCrystal lcd(12, 11, 5, 4, 3, 2); | |
void setup() { | |
// set up the LCD's number of columns and rows: | |
lcd.begin(16, 2); | |
// Print a message to the LCD. | |
lcd.print("Infinity"); | |
} | |
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); | |
