資料介紹

電路板圖如下：

成分

ARDUINO UNO REV3	× 1
通用 220 歐姆電阻器	× 1
LCM-S01602DSF/A Lumex 光電/組件公司	× 1

描述

Arduino UNO 液晶屏

建造盾牌：

組裝：

盾構圖如下：

LCD RS 引腳到數(shù)字引腳 12

LCD 使能引腳到數(shù)字引腳 11

LCD D4 引腳到數(shù)字引腳 5

LCD D5 引腳到數(shù)字引腳 4

LCD D6 引腳到數(shù)字引腳 3

LCD D7 引腳到數(shù)字引腳 2

LCD R/W 引腳到 GND

LCD VSS 引腳至 GND

LCD VCC 引腳至 5V

LCD LED+ 通過 220 歐姆電阻器至 5V

LCD LED- 到 GND

電阻器進入電阻器符號。每個孔中都有焊針。就是這樣！

使用盾牌：

要使用顯示器，您必須在 Arduino IDE 上安裝 LiquidCrystalDisplay 庫。

我將在下面留下一個 Hello world 示例來使用顯示器。;)

代碼

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)
