| + | 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) | ||
