LiquidCrystal Library - Blink
|
||||||
|
|
||||||
|
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 makes the
|
||||||
|
cursor block blink.
|
||||||
|
|
||||||
|
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
|
||||||
|
* 10K resistor:
|
||||||
|
* ends to +5V and ground
|
||||||
|
* wiper to LCD VO pin (pin 3)

LiquidCrystal Library - Shift
|
||||||
|
|
||||||
|
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 demonstrates how to use shiftLeft() and shiftRight()
|
||||||
|
to move the cursor.
|
||||||
|
|
||||||
|
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
|
||||||
|
* 10K resistor:
|
||||||
|
* ends to +5V and ground
|
||||||
|
* wiper to LCD VO pin (pin 3)
