Dog food exchange machine using plastic bottles

Abstract

The objective of this study was implementation of microcontroller to construct Appl to control the operation of the Dog food exchange machine using plastic bottles system. To study an operation control of microcontroller system operation and the to create construction of a Dog food exchange machine using plastic bottles. The component of Dog food exchange machine using plastic bottles are divided into 3 parts: 1) parts of detecting plastic bottles sensor 2) part of the motor control 3) part of the vending machine. Results of the study of Dog food exchange machine using plastic bottles. used in 2 ways: 1) plastic bottle vending 2) coin vending for 10 baht. When the total number of bottles is set at 15 bottles, the plastic bottle vending machine will not work until the Reset button is pressed. Can still work normally
