PaperDIY Assembly Kit · File : wifi_web_server.ino · Language : C++ (Arduino) · Use case : Créer un serveur web local pour contrôler la carte via un navigateur.

Minimalist web server to control an output and display status.

Modify SSID and PASSWORD with your WiFi credentials. Upload the code. Open Serial Monitor to get the local IP address. Access this IP from a browser on the same network to interact with the board.
