Hello arduino forums. What I would like to accomplish is to build an MDB tester for my vending company. I need a bit of help though and I really don't know where to start.
What I have so far are a few arduino uno 's and some lcd displays. I would like to basically build a tester that I can hook a MDB bill acceptor or coin mech up to, to test them. I need the lcd display to display the amount of money that had been passed through the device in test, and if it rejects the bill or coin it will throw an error or some there message. Any help getting this started and so on would be greatly appreciated.
How do the vending machines communicate with the bill acceptors? You could hook up an oscilloscope to see what the MDB is sending. Do you have any other documentation?
I did not read through the whole thing, but I would not consider what you propose, except on a PC. You would have to program a complete master controller and then add more to be able to diagnose error conditions that may be encountered.

I understand that, and that would be fine but wouldn't it be harder to make a windows based program to test devices such as changers and note validators? With arduino it would just need to be a test based lcd mounted at the front with some buttons and connectors.
