The objective of this work is to design and Implementation of a microcontroller based electronic circuitry for vending machine. Normally, we need to use vending machine to provide instantaneous refreshment for the customers. In this system, initially a Advance Virtual RISC microcontroller act as building block can be used to monitor the vending machine. In such cases, a Programmable SystemOnChip microcontroller can be used in place of conventional approach. Then, same building block will be configured as a transmitter and receiver for operation of controller with the help of fingerprint module.Also,we propose an implementation technique for vending machine with the goal of getting recharge option for customer using fingerprintbased authentication. We implement the proposed design based on AVR microcontroller.
