先從簡單的LED控制開始吧
另外，因為我不是軟體出身，所以code寫得很爛，請多包涵:D
上面的影片，主要是利用Arduino的數位輸出腳，來控制8x8的LED
顯示0~9的字型
首先，利用手動來控制 8x8 LED發亮，並且了解一下腳位如何控制
這顆8x8 LED是在光華商場對面樓下的電子材料行買的
料號: LM12883SRWK 共陰極 矩陣式8x8 LED
如何確認控制腳位? 先在excel框好8x8的格子
左邊的圖，上面那排是LED的正極(Anode)腳位4,7,2,8,12,1,14,9
左邊那排是LED的負極(Cathode)腳位13,6,5,10,3,11,15,16
如果要讓第一行，第一列(a)的LED發亮，就要在腳位4灌電壓，腳位13下地
(b) = pin7 (+),pin6 (GND) 依此類推
但唯一的問題就是，因為這只有16支腳，若要同時間做出fig-2這種顯示是無法的
因為，當你亮(j) = pin4(+) , pin6(GND) , 同時要亮(k) = pin7(+) , pin13(GND)
這時候pin4(+) , pin13(-) = (a) , pin7(+) , pin6(GND) = (b)就會變成fig-3
不過這問題，稍後我們可以利用軟體的小技巧來達到fig-2的效果
接下來在excel上面先畫好我們想要的字型，例如0~9
因為Arduino Uno只有提供14支數位的輸出腳，所以我們用6x6的格子來畫
所以6+6=12支腳，另外我們正腳位使用7,2,8,12,1,14
對應Arduino的數位輸出腳1~6 , 負腳位依此類推
根據這個電路圖，在每個LED正腳位回到DIGITAL輸出之間串220ohm的電阻
避免過大電流燒掉LED或是造成亮度不均的問題
