Android Controlled Lawn Mower Using Bluetooth and WIFI Connection

摘要

This study was designed to clean the school field in an easier, faster, safer and more cost-effective way. The device has the following hardware such as Arduino Uno microcontroller, HC-05 Bluetooth module, WIFI module, two 12 volt wiper motors as wheels, 24 volt EBike blade motor, motor driver, two caster wheels, switch and two 12 volt 7 Ampere rechargeable lead acid battery that are connected in series. The device can be used using Android phone with installed ENIRO App. The ENIRO App was constructed using MIT App Inventor. In controlling the lawn mower, Bluetooth and WIFI connection can be used. The maximum distance of Bluetooth is up to 58 meters or 190 feet. The maximum distance of WIFI connection is up to 152 meters or 500 feet. In continuous usage of the device up to two hours, the area of mowed grass is 30 meters by 20 meters. The project passed the project evaluation and determined the quality of the project. It was evaluated by 20 evaluators using the criteria: functionality, reliability, usability, efficiency, portability and maintainability. KeywordsArduino, Android, WIFI, Lawn mower.
