6 | based on official arduino LiquidCrystal Library |
||
7 | - display() and noDisplay() |
||
8 | |||
9 | Demonstrates the use a 16x2 LCD display. The LiquidCrystal |
||
10 | library works with all LCD displays that are compatible with the |
||
11 | Hitachi HD44780 driver. There are many of them out there, and you |
||
12 | can usually tell them by the 16-pin interface. |
||
13 | |||
14 | This sketch prints "Hello World!" to the LCD and uses the |
||
15 | display() and noDisplay() functions to turn on and off |
||
16 | the display. |
||
17 | |||
18 | The circuit: |
||
19 | * LCD RS pin to digital pin 12 |
||
20 | * LCD Enable pin to digital pin 11 |
||
21 | * LCD D4 pin to digital pin 5 |
||
22 | * LCD D5 pin to digital pin 4 |
||
23 | * LCD D6 pin to digital pin 3 |
||
24 | * LCD D7 pin to digital pin 2 |
||
25 | * LCD R/W pin to ground |
||
26 | * 10K resistor: |
||
27 | * ends to +5V and ground |
||
28 | * wiper to LCD VO pin (pin 3) |
