Projects — Beginner

This project is the "Hello World!" of Arduino. In this project, we are going to learn about physical outputs and two electronic components, while performing the simplest project in the electronics sea of projects.

In this example, we use the analogWrite() function to fade an LED on and off. analogWrite() uses pulse with modulation (PWM) to create an analog-like behavior from a digital output. This behavior is achieved by switching the output on and...
