Vending machine Design ?

What are you asking for?

Are you after a commercial vending machine circuit complete with coin mechanism?

Is this a school project to demonstrate the application of logic?
... If so then do you want relays, TTL, CMOS circuits or just truth tables?

there was a thread about wending machines not so long ago. use the 'search' facility to try and find it. It went into quite a lot of depth, including the use of inductors (I think) to find out which coin had been inserted.
