2、載線方便下載更新程序，可以不安裝。D1D31 ，是31個3mm 紅色發(fā)光二極管，在線路板上排列成心形，可以將發(fā)光顏色更換為其他顏色。R1R8、R10 R32 為限流電阻，控制通過二極管的電流，避免過大電流燒毀發(fā)光二極管。元件參數：D1D31 3mm 紅色發(fā)光二極管R1R8、R10 R32 八分之一瓦電阻， 680歐姆U1 DIP40封裝的STC89C52RC 單片機C1、C4 10uF/50V 電解電容C2、C330pF 瓷片電容Y1 11.0592MHz 晶振R9 4.7K 歐姆電阻元件放置分布圖說明：在安裝元件時，可以最先安裝 LED 發(fā)光二極管，注意二極管的極性方向。新的二極管長引腳的電

3、極是陽極，如果剪過引腳，要是用萬用表判斷出來陰極和陽極。在Altium Designer的 PCB 圖中，整個圓形中有切掉部分圓弧的一側是陰極。如上圖所示。底層布線連接圖（底視）底層布線連接圖（頂視）說明：焊接上元件后，先不要盲目的慌著剪去多余的過長引腳，可以考慮將長出的引腳折彎與其他含盤點相連。繞行元的，有交叉的可以考慮使用帶絕緣的單芯鍍錫線進行連接。具有5種模式輪流 顯示的 心形流水燈 單片機 C51 源程序。#include <reg51.h>sbit x1=P07;sbit x2=P06;sbit x3=P05;sbit x4=P04;sbit x5=P03;sbit x6
