自制搖搖棒

嘿嘿，自我感覺不錯。就是這個用手搖晃的東西有點累。
補充下，這個慣性開關就是把單片機的兩個引腳引出來，然后在負極上接上一根彈性導線，搖動的時候這個彈性導線會向兩邊擺動而觸動到兩個引腳（為了增加慣性，我得彈性導線很長，并且在頂端彎了幾個圈增加慣性）。為了防止擺動出來，我在兩個引腳上加了一段帶皮導線，這樣就能隨便亂晃，不至于導線出來

正面，上面一排是發光二極管。右下角的是慣性開關

關燈后的效果（視頻截圖，相機拍不到）

STC12C5a60S2單片機

原理圖，上面少了外震蕩電路和上電復位電路。其實這個單片機在寫入程序后可設置為內部晶振，然后晶振和復位 ...

源程序：

#include //單片機頭文件
#define DY_DELAY 5 //設置每一個點顯示的時間長度（1~20）
sbit KEY1 = P1 ^ 2; //搖動慣性開關
sbit KEY2 = P1 ^ 3;
sbit LED1 = P0 ^ 3; //LED燈定義，低電平時亮（自上到下）
sbit LED2 = P0 ^ 4;
sbit LED3 = P0 ^ 5;
sbit LED4 = P0 ^ 6;
sbit LED5 = P0 ^ 7;
sbit LED6 = P4 ^ 6;
sbit LED7 = P4 ^ 5;
sbit LED8 = P4 ^ 4;
sbit LED9 = P2 ^ 7;
sbit LED10 = P2 ^ 6;
sbit LED11 = P2 ^ 5;
sbit LED12 = P2 ^ 4;
sbit LED13 = P2 ^ 3;
sbit LED14 = P2 ^ 2;
sbit LED15 = P2 ^ 1;
sbit LED16 = P2 ^ 0;
