Learn how to control multiple LEDs with Arduino, using the array + function combination. Make your code much more readable and scalable.

This tutorial shows how to use an example of ezLED library that controls multiple LED in an array.

As an example of how to use arrays on the Arduino, let’s build a circuit that controls an array of LEDs. Each LED in the array will blink on and off one after the other. This project uses the following parts:

Learn how to setup single and multiple LED matrix displays on the Arduino, and how to scroll text and the readings from a sensor.

Mar 10, 2015 · In this tutorial, I will show you how to build a fancy 8 by 10 Arduino LED matrix (with scrolling text and animations) using an Arduino and a 4017 decade counter. You can also buy an assembled LED matrix online.

In this complete tutorial you will learn how to use an LED with Arduino. First, you will setup your circuit with an Arduino board and an LED, and then discover different ways to control the LED. I will use Arduino Uno for the examples but the instructions here apply to any Arduino board.

Mar 14, 2025 · LED displays are often packaged as matrixes of LEDs arranged in rows of common anodes and columns of common cathodes, or the reverse. Here's a typical example, and its schematic: These can be very useful displays. To control a matrix, you connect both its rows and columns to your microcontroller.

I previously made an Arduino controlled scrolling text display with a single 16x16 color LED array. This Instructable improves on that with a 48x16 array made up of three 16x16 LED panels, controlled with Arduino Uno.

Jul 11, 2016 · In this technical article, I will teach you what an LED array is, how the LEDs are connected, and how to drive them efficiently using microcontrollers. I'll use an Arduino as an example. LED Arrays

DIY LED Array (Using Arduino): INTRO: Have you ever wanted to make a simple project that makes LEDs seem to be moving? No? That's what I thought. Well, if you ever have wanted to make something similar, you're in the right place!
