This repository contains the library and example code to work with our Whadda LED bar graph display module (WPI471). The library can also be use to drive any other LED bar graph module that uses the ...

The aim of this project (or more specifically the code), is to see how well object orientated programming (OOP) works on an embedded platform. In other words, this is a software engineer's take on a ...

With the rapid growth of embedded systems, and, in particular, IoT devices, there has been a growing need for improvements in the rechargeable battery systems that power them. In particular, many ...

In this project we are going to design an 8x8 LED matrix display, for that we are going to interface an 8x8 LED matrix module with Arduino Uno. An 8x8 LED matrix contains 64 LEDs (Light Emitting ...

Take a gander at the Giant LED bar graph which [Chunky Hampton] recently completed (from this image we don’t think the nick name suits him). It’s simple both mechanically and electrically, but we love ...

This circuit uses two National Semiconductor LM3914 dot/bar-display-driver ICs to implement a two-digit, 0 to 5V LED voltmeter that mimics a subranging flash ADC. An LED bar graph comprising five LEDs ...

Welcome to our blog post on interfacing the WS2811 (5V) RGB LED strip with Arduino! In this guide, we will walk you through the process of connecting and controlling WS2811 LED strips using an Arduino ...
