Coding の ORZ : LCD 顯示動畫

兩年前的研討會?

我以為要再買晶片才能燒錄沒看到，偶然發現有附usb線，上面的lcd我們來拔下來做一下小實驗吧

首先我們先來查腳位

再來是

萬用Ardunino

	/* Lab9 - 在 2x16 LCD 上顯示 "Hello World" 訊息
	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 Potentiometer:
	* ends to +5V and ground
	* wiper to LCD VO pin (pin 3)

	This example code is in the public domain.
