14. How to Fix ESP32 Button Interrupt Issues (Different Solutions)

A simple button press turned into chaos — false triggers, random resets, and an ESP32 with a mind of its own. In this video, I’ll show how I finally fixed unreliable button interrupts on the ESP32 using a mix of hardware and software tricks. From pull-ups to Schmitt triggers, and even a touch of humor — this is the journey to tame the button. 🔧 Covers ESP32, Arduino Micro, and Wemos D1 Mini 💡 Includes debounce circuits, Schmitt trigger fix, and timer-based alternatives @Atomic14: ESP32 pinouts https://github.com/atomic14/esp32-s3-...
