help for our project!

hai guys we think of having examination booklet vending machine as our project can anybody help me identify what are the components that we may use for this project?..and please give me a sample block diagram of other vending machine, so that it will serve as our guide.

you're help is highly appreciated! thanks in advance...

Try googling to find a block diagram of a vending machine. As for components you will need at least a vandal/thief resistant housing for the booklets, a mechanism for picking one booklet off a pile and presenting it to a customer, and a mechanism for accepting payment from a customer.
