The vending machine is a kind of cash driven machine that automatically distributes snacks, drinks and other consumer products automatically. Consumer pay coin into a slot, once a choice is made by pressing the push button, the machine dispenses the item purchased. Money, card or coin-based product vending machine by using embedded microcontrollers; Arduino and Raspberry Pi are currently used in systems. By using these microcontrollers, it is complicated when there was a technical error. In this review paper, we have created a multi-product coin type vending machine by using Mitsubishi PLC. The Programming Logic Controller (PLC) used automatically to monitor and control with high speed, efficiency, and reliability. Switch ON the power supply. Put the coin in the coin acceptor, and then select the product by pressing push button. The motor starts rotating along with the spring and moves the selected item until it released from the spring. The Hall Effect sensor used to count the rotation with the help of the magnet to sense. When the product released from the spring the motor stop rotating and the released product is ready to dispense. [1],[ 3],[5]
