描述

Arduino UNO 液晶屏

建造盾牌：

组装：

盾构图如下：

LCD RS 引脚到数字引脚 12

LCD 使能引脚到数字引脚 11

LCD D4 引脚到数字引脚 5

LCD D5 引脚到数字引脚 4

LCD D6 引脚到数字引脚 3

LCD D7 引脚到数字引脚 2

LCD R/W 引脚到 GND

LCD VSS 引脚至 GND

LCD VCC 引脚至 5V

LCD LED+ 通过 220 欧姆电阻器至 5V

LCD LED- 到 GND

电阻器进入电阻器符号。每个孔中都有焊针。就是这样！

使用盾牌：

要使用显示器，您必须在 Arduino IDE 上安装 LiquidCrystalDisplay 库。

我将在下面留下一个 Hello world 示例来使用显示器。;)

代码

你好世界！

?	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)
