Construction of Vending Machine Operated by Arduino Microcontroller

Mechatronics consists of an integration of mechanical engineering with electronics and computer systems. The word mechatronics is made by combining the words mechanics and electronics. Mechatronics is a branch of engineering which combines many fields of mechanics and electronics. This work will explain one of those examples of mechatronics systems, and that is the vending machine. An example of mechanics in this work is a conversion of rotational movement to translation movement via a helicoil spring which rotates with the help of the step motor and usesthe potential energy of the coin when sorting in the money mechanism, and the examples of electronics are electronic components such as step motor, Arduino microcontroller, push buttons etc. The machine works by inserting a certain amount of money through the opening intended for it which the sensors will read and print on screen the amount of money that is currently in the machine. If the condition is fulfilled, that is if the machine has enough money we need for the product, by pressing the push button, which is positioned in respect to the product position in the vending machine, the machine will dispense the required product. This work will also show the schematic representation of connecting electronic components and the very construction and assembly of the vending machine.
