This article explores how to create a PC-based appliance control system using Microsoft Visual Basic (VB6) for a graphical interface and Arduino hardware for relay control.
The system comprises two main parts: a software program written in Microsoft Visual Basic (VB6) and a hardware module controlled by the ATmega328P microcontroller.
Communication between the PC and the microcontroller occurs through a USB-to-TTL serial converter.
The ATmega328P microcontroller, an 8-bit single-chip microcontroller, is the heart of the system.
The circuit is designed to receive commands from the PC, process them using the ATmega328P microcontroller, and operate relays to control connected appliances.
The Arduino IDE is a free, open-source platform used to write, compile, and upload programs to microcontroller-based boards.
The design ensures safe and efficient operation, making it suitable for home or industrial use.
By combining the power of the ATmega328P microcontroller, the flexibility of Arduino programming, and the user-friendly Visual Basic GUI, this system provides a robust and scalable solution for home and industrial automation.
It’s simplicity, coupled with the ability to customize and expand, makes it an ideal project for enthusiasts, students, and professionals.
This implementation is a step towards smarter living and more efficient automation.
