Introduction
• A vending machine is a system which accepts a coin and dispenses the product we want.
• The idea of vending machine is implemented through a state machine.
• A finite state machine, so names because the sequential logic or flip-flops that implements them can be in one of a finite number of possible states.

Because it doesnâ„¢t have line of sight problem and it is capable of both point to point and point to multipoint wireless communication. Moreover, attachment facility of low cost, commercial microcontroller as the host controller interface had facilitated straight and effectiv ....etc
