Coin Receiver and Coin Changer

In this weekend, my partner and I decided to explore the different kinds of vending machine in the campus. And write the code for the

The first place is the central teaching building. The second place is the electronic and electrical building. After using these vending machines, we instantly found that we need to add the display part for the customor.

In this project, I really found that it is so interesting to apply what we know to the real life.

The first component is the coin receiver, which is the part that allows the customer to insert the coins.
Here is the partial VHDL code.

The second component is the coin changer, which is the part that cotrols the changes.
