| 2 | LiquidCrystal Library - Cursor
|
---|
| 3 |
|
---|
| 4 | Demonstrates the use a 16x2 LCD display. The LiquidCrystal
|
---|
| 5 | library works with all LCD displays that are compatible with the
|
---|
| 6 | Hitachi HD44780 driver. There are many of them out there, and you
|
---|
| 7 | can usually tell them by the 16-pin interface.
|
---|
| 8 |
|
---|
| 9 | This sketch prints "Hello World!" to the LCD and
|
---|
| 10 | uses the cursor() and noCursor() methods to turn
|
---|
| 11 | on and off the cursor.
|
---|
| 12 |
|
---|
| 13 | The circuit:
|
---|
| 14 | * LCD RS pin to digital pin 12
|
---|
| 15 | * LCD Enable pin to digital pin 11
|
---|
| 16 | * LCD D4 pin to digital pin 5
|
---|
| 17 | * LCD D5 pin to digital pin 4
|
---|
| 18 | * LCD D6 pin to digital pin 3
|
---|
| 19 | * LCD D7 pin to digital pin 2
|
---|
| 20 | * LCD R/W pin to ground
|
---|
| 21 | * 10K resistor:
|
---|
| 22 | * ends to +5V and ground
|
---|
| 23 | * wiper to LCD VO pin (pin 3)
