Prototype Smarthome Berbasis Mikrokontroler Arduino Uno dan Android

Summary

Widya presents her thesis project on a smartphone prototype using an Arduino Uno microcontroller and Android. The system integrates an Arduino Uno R3, an HC-05 Bluetooth module for connectivity, a step-down converter, a 12V transformer, and an 8-channel relay for controlling home appliances. She demonstrates how each channel operates various lights and doors, including living room, bedroom, garage, and terrace lights, as well as automated door locks for the main entrance and garage. Widya showcases the setup, Bluetooth connection, and how to control the devices via an Android app. She concludes with a successful demonstration of the system's functionality.
