Builiding a machine
I want to build a simple electronic machine:
1.The user inserts a coin.
2.He chooses from the screen menu some options.
3.After the user had chosen,he gets a ticket from the machine.
The machine inclides PC,coin acceptor,printer.
So my question is:
How to connect the coin acceptor with the PC and the software of the machine,so the machine starts only afte the user inserts a coin?May be I need a PCB/controller/?
