4 digit 7 segment display with Arduino

In this video, we explore how to control a 4-digit 7-segment display using an Arduino and the SevSeg library. Learn how to easily display numbers and text across multiple digits, and understand how multiplexing works to reduce the number of pins needed to control the display.

We'll walk through the key functions of the SevSeg library like setNumber() and setChars(), and demonstrate how to implement smooth timing without using the delay() function by leveraging the millis() function. This method ensures smooth transitions between different digits and prevents flickering.

Whether you’re building a digital clock, counter, or any project involving numeric displays, this tutorial will guide you step-by-step in setting up and programming your 4-digit 7-segment display.
