Hi, it's time for me to hand in my homework now. :grin:

I have spent a great weekends at home and finish this interesting suite.



 

I think you should explain in brief manner what's going on here. Should not you?
 

yes, and here are the compotents.


The circuit is mainly composed of pulse generator and a decimal counting circuit. And the multivibrator is formed by NE555 and the peripheral components. After press S1, Q1 is on and PIN 3 of NE555 outputs the pulse. Five output ends of CD4017 output the high level by turns. Seven LED light up and indicate 1-6 points with the results of the different combination between resistors and transistors.

Thanks,
 

They are not homemade PCBs. The poster ICStation was banned for putting advertisements in the DIY section.
