ESP32 | Switch Interfacing | Wokwi Simulator | #iot

Interfacing a switch with an ESP32 microcontroller is another fundamental task. Below is a simple example of how to interface a push-button switch with an ESP32 using the Arduino IDE:

Hardware Setup:
Connect one terminal of the switch to a GPIO pin on the ESP32.
Connect the other terminal of the switch to ground.
Optionally, use a pull-up or pull-down resistor to ensure a stable reading when the switch is not pressed.
