Physical vs
Software Button
Are physical buttons still worth using in 2026? I compare a standard LED circuit with a physical push-button against a software-controlled version that replaces the hardware entirely — simplifying the build with code instead of components.
The hardware drop
Instead of wiring a push-button to the breadboard, the
ESP32 broadcasts its own local Wi-Fi access point
(ESP32_Button). No internet required.
The seamless UI
The standard ESP32 web button reloads the whole page on
every click. To make it feel like a native app, a hidden
JavaScript fetch() call signals the ESP32
silently in the background instead.
