C语言编写的AVR单片机跑马灯程序，通过轮循控制PortB口电平，实现LED发光二极管的点亮与熄灭，是掌握AVR单片机端口控制和练习C语言编程的非常不错的应用实例。-C language program AVR microcontroller Marquee, by round robin control PortB port level, the LED light emitting diode and off, is to master the control of the AVR port

光立方是一学习单片机非常好的练习材料。拿8*8*8光立方举例，它是由512个发光二极管按照立方体的方式搭建焊接起来的，有层共阴束共阳和层共阳束共阴两种方案，每一层有8*8个发光二极管，共8层。用c语言编译单片机程序使自定义动画效果得以实现。-Light Cube is a very good practice material for learning a single chip. Take 8* 8* 8 light cube example, it is by the 512 light-e
