Blinking LEDs In Sequence (Pin-By-Pin)

Introduction

Arduino is often used with input and output peripherals. Common output components used with Arduino in mini-projects are LED and Buzzer. Similarly, a potentiometer is a commonly used input device for analog input to Arduino. In this article, we will dive into understanding these components and making exciting mini projects using these.
