第一次发帖，二进制时钟
一直以来，都是在本论坛学习，至今一直没做出过东西，废话不多说了，看见其他创客做了二进制时钟，自己也想做个，
没想到慢慢就做成了，虽然代码都是组装的，但是以后一定要自己写代码
硬件ds1307
uno
max7219点阵模块
UNO与ds1307连线
SDA(A4)-SDA
SCK(A5)-SCK
max7219模块与UNO连接
10-CS
11-CLK
12-DIN

LedControl库
ds1307库我忘了链接在哪了，谁需要联系我
http://playground.arduino.cc/Main/LedControl#Source 朋友你好，请问arduino uno与max7219如何连接
max7219模块与UNO连接 10-CS 11-CLK 12-DIN 我用的是模块化的点阵
