建议：用可编程芯片来做。
比如：51芯片。（做你现在这个功能足够了）
其他的counter, timer就用编程来实现就可以了。很方便，而且随时可以变，功能也可以扩展。
编程建议用fc51。和c语言差不多，很简单，实用。
希望能帮到你。
only 74 family of IC + 555 is provided in that ass
inment.
But mind telling us more about fc51? Is it a logic array?
all EE ppl learn programmable logic array, but no first hand experience at all. could you share with us?
