You have to design and simulate a circuit for a vending machine using switches, lamps (LEDs) and seven- segment displays. The following design specifications are to be followed: The vending machine takes two types of inputs, coins and choice of product. The vending machine should accept and differentiate between different money denominations. Assume that there are only 1, 2, and 5 rupee coins available. The different type of coins can be denoted by three different switches. This machine sells 3 different type of products, each with different prices. You can chose the price of each product yourself. Users are only allowed to purchase 1 product at a time. Two types of outputs are generated by the vending machine; indication of product purchased and the amount of change that needs to be returned. One out of 8 LEDs for each product should light up indicating a successful purchase. Another LED should light up if the input money is less than the price of any desired product.

NOTE : KINDLY DON'T GIVE ME THE STATE DIAGRAM OR STATE ENCODING I NEED

Task Implementation Each of the modules given in the design specification should be implemented in and tested using Proteus. Design a digital circuit. "A proteus diagram please"
