Simulated GPIO pull-up and pull-down circuits for push buttons. Original circuits are posted in article "Push button with ESP32 – GPIO pins as digital input"
https://microcontrollerslab.com/push-button-esp32-gpio-digital-input/

Both circuits are suitable to connect buttons and keyboard to Arduino, ESP32, RP2040 etc. and derived module input-only pins.

Bottom circuit in real life use inverter gate with Schmitt trigger (not included in EveryCircuit) that allow to achieve exceptional debouncing capabilities.
