The third lab day

Today, we offically begin to write the code for our vending machine.
1. The first decision we made is to write the code in VHDL. After doing the research, we found that VHDL is easier to write and more efficiency.

2. Then we try to design the top level structure of the vending machine. We think that there should be five components for the vending machine. Coin receiver, product selector, controller, product dropper and the coin changer. We decided to write separated codes for each part and then combine them into a single simple package.

3. In this project, we use the softeware Altera Quartus II and the DE1 development board.
