A Vending machine at Canada’s Wonderland dispenses candies for children in a park. The machine only accepts a
quarter (Q: 25 cents), a dime (D: 10 cents) and/or a nickel (N: 5 cents). You cannot put two coins of the same value
though. You can choose a different type of candies from the machine:
Gummies – 5 cents, Licorice – 10 cents, Lollipops – 15 cents, Caramels – 35 cents, Chocolate – 40 cents.
The machine dispenses a candy only if the exact amount is entered.
You are asked to design the simplest circuit that will control the situation and dispense a candy.
Answers
Answer:
Given, Area of bigger rectangle =(6×5)cm=30cm
2
Area of smaller rectangle =(3×2)cm=6cm
2
Therefore, area of remaining sheet of paper=Area of bigger rectangle − Area of smaller rectangle
=(30−6)=24cm

The machine does not accept two coins of the same value, the circuit can be designed to detect the type of coin inserted and compare it with the previously inserted coin. If the same type of coin is detected, the circuit will reject it.
We must first comprehend the reasoning behind how the vending machine ought to operate in order to design a circuit for it.
Only if the precise amount is entered should the machine dispense sweets. Two coins with the same value shouldn't be accepted by the machine.
Once the precise amount is entered, the machine should distribute the selected candy With the logic presented above, the following circuit architecture is possible:
For the three different coin types, the circuit should have three input buttons (quarter, dime, and nickel).
The circuit ought to contain a display that indicates the entered amount.
The five different candy flavors should each have a button on the circuit.
For the purpose of dispensing the selected candy, the circuit needs incorporate a dispenser mechanism.
The circuit can be designed using microcontrollers, sensors, and actuators. The sensors will detect the coins inserted and the microcontroller will calculate the total amount. If the total amount is equal to the price of a candy, the microcontroller will activate the dispenser mechanism to dispense the candy.
To ensure that the machine does not accept two coins of the same value, the circuit can be designed to detect the type of coin inserted and compare it with the previously inserted coin. If the same type of coin is detected, the circuit will reject it.
