Hi
I just read this posted message !!
I am not sure whether this is still of any help to you or not..but still...

I guess its very simple... you don't need a counter as such though you can design it with a counter...

but i would suggest you to draw a state machine diagram and do it..
if you could send me the proper problem statement i can provide you with tha machine logic and state-diagram also if time permits, i might as well provide you with the circuit diagram...
its really a fun..

: Hi,


: I am an EE student at OSU. I am in ECE 271 and the final project is to build a vending machine logic unit.


: I will be using switches to represent nickels and dimes. the package release is true for 25 cents or greater.


: I have 4 JK flip flops, 4 D flip flops and a variety of logic chips "And, not, or, etc..."


: I am a little stuck on how to implement the logic unit. I figure there has to be two counters, but don't see how to use them.


: any input will be helpfull

: thanks.
