Design and build a prototype of a coin-sorting and coin-counting

machine

Following are the basic ideas of the project:

1. The machine should be operated by the following NEW Singapore currency coins ONLY:

10 cent, 20 cent, 50 cent and 1 dollar coin.

2. The machine has to definitely ensure DUPLICACY OR FRAUD OF COINS.

Any coin apart from the above 4 type of coins should not be accepted by the machine

and returned in the tray back. Any coins of neither similar dimensions of the above nor

similar weight should be able to pass through the machine. It has to necessarily be only

the above 4 coins.

3. The machine should SORT COINS.

It should distinguish between each coin denomination and store into different

departments inside the machine upon insertion.

Eg: When 10 cent coin is inserted in the machine, it should be stored into compartment

1; when 20 cent coin is inserted, it should be stored into compartment 2. Again when 50

cent is inserted, it should go into compartment 3 and when 1 dollar coin is inserted, it

should store into compartment 4.

4. The machine should COUNTS COINS & DISPLAY THE AMOUNT

It should count each amount of coin inserted and display the total amount on the screen

inserted by each user.

Eg: When customer 1 inserts a 10cent coin, it should display “$0.10”. Upon that when

he inserts a 50cent coin; it should display “$0.60” i.e the sum of 10 cents and 50 cent.

Plus on inserting another dollar coin, it should display “1.60”.

When customer 2 comes and presses the Start button, the counter should start from 0

and display the amount gradually as he starts inserting coins the similar way.
