Push buttons are core components of Arduino projects because it gives a user the ability to trigger a variety of actions and makes your electronics projects more interactive. In order to incorporate buttons into your circuits and have them behave reliably, you’ll have to understand the concept of pull up and pull down resistors. In this lesson, we’ll start with a few popular projects like using buttons as momentary switches, toggle switches and even a dimmer.
