This repository contains a single Arduino sketch for an RTL8720dn-based WiFi deauther. It hosts a captive web interface on the board's own WiFi network, scans for nearby access points, and allows a user to initiate deauthentication attacks against selected networks by sending crafted deauth frames. The architecture is a monolithic embedded firmware with a simple event loop: it serves HTML pages, parses HTTP POST/GET requests, and uses a submodule for packet injection. The code is tightly coupled to the target hardware and lacks modularity, abstraction, or tests. It is a functional but unrefined hobbyist project with no reusable components.
