This is our third lab day for the Year 2 group
project. During this lab day, we have revised our general block diagram to delete the parts that have similar functions and to increase the efficiency of the machine. In detail, we have deleted the cancel function block. Since the basic function of
cancelling is to give the money back, it could be included in the change block.

We have also designed the ASM chart for every block.
