Network Subnet Calculator System

A web-based subnet calculator developed using Python, Flask, HTML, CSS, and JavaScript.

The application calculates network information such as Network ID, Broadcast Address, Subnet Mask, First Host, Last Host, and the number of usable hosts.

The project also integrates with Arduino through TCP/IP and Serial communication, allowing subnet calculations and communication data to be exchanged between the web application and the hardware.

I worked on the web interface, backend logic, subnet calculations, and communication between the application and Arduino.
