There are two configuration modes to interface a push button with the ESP32 board. Let’s discuss both these modes one by one. Pull-Up Mode In Pull-up mode, when a push button is not pressed, a logic high input appears on the ESP32 GPIO pin. Because a 5V signal appears on the inp...

I am trying to get together code for my ESP32 WROOM to control door opening via a relay and keypad. I have made this work but I want a push button on the inside of the door that opens the door, this button should be toggeling the relay. I also want to be able to use at least...
I am new to ESP32 platform. I have ESP32_Core_board_v2 which doesn't have any dedicated Push Button GPIO on board. I can attach external switch with the GPIO pins but I want to use "Boot" button as push button GPIO meaning if I press it while the program is running, it will cal...
On ESP32 the last GPIO pins are input-only and it says they have no software pullup or pulldown resistors. Can I still use them to connect to pushbuttons in the way that is described athttps://www.instructables.com/Arduino-B ... -resistor/(That is, without any external resistor, co...

Two pushbuttons and a rotary encoder such as this one. An intuitive interface. A rotary encoder with built-in push switch only. On ESP32 physical buttons may be replaced with touchpads. It is larger and more complex than nano-gui owing to the support for input. It enables switching betwe...
