The push button is one of the simplest components, yet one of the most widely used in electronics. It allows interaction with a system by sending a signal to a microcontroller or another electronic circuit when the user presses it. In this text, we will explore the operation of the push button, its different types, and how to use it in practical projects with boards like the Raspberry PICO. Here is the electronic schematic for the push button on Raspberry PICO:
