Arduino LED Matrix

https://youtu.be/Eu9ExmHkkIk https://youtu.be/_srC_gPAEP0 In this short tutorial you will learn how to make an Arduino-powered LED matrix. Unlike several other designs, this one uses a "companion" computer to notify the Arduino which LEDs should be powered. I have provided the code for the Arduino, as well as some Java code for displaying text on the LED matrix (this includes a custom-made 7x5 character fon ...

LED Matrix Controller Using 4Duino

In this project, we will use the digital pins and screen of the 4Duino to create a 5×7 LED matrix controller with a user graphical interface. https://youtu.be/fSCNCFmbSJc An LED matrix is essentially many LEDs packaged in a dot grid format in order to produce pictures or large text. They’re commonly used for signage purposes in the public space. The LED matrix utilised in this project is made by multiplexin ...

VU Meter – LED Noise-o-Meter for Classrooms

I built this a short while ago as an idea to use in a primary classroom setting. Poster displays are often used by primary teachers wanting to control the noise levels in their classrooms but I wanted to add technology to make it dynamic and responsive. The motivation for this came after seeing the Adafruit Digital NeoPixel LED Strip online and realising its potential as part of a VU meter. Everything else ...

Arduino LED Exploration

Arduino LED ExplorationMy program shows you all of the data on your Led from the first light to the normal operation light. From that data you can pick an RS that is good light, but lower in current. You must build the circuit to run my program. You must open a terminal window when you run my program. Bright led can waste a lot of current. Using a higher RS like 470 to 1k you can save almost half of the cur ...

Light Animations Using Arduino and MATLAB

Light animations are visually appealing and hence widely used for advertising purposes. In this project, we present a MATLAB-based graphical user interface (GUI) approach to control the glowing pattern of a number of light-emitting diodes (LEDs). Use of GUI is advantageous since the user can control illumination patterns while performing other tasks in the PC. This project creates five different lighting pa ...

Interfacing a Laser LED with Arduino

This project turns on and turns off a laser LED after every second. It can also monitor its own supply voltage level. The circuit can be extended for use as an audio-visual alarm system for security applications. Keyes KY-008 laser transmitter module is available at www.ebay.com. But there is a lot of confusion regarding this particular module; it is impossible to find its datasheet or any kind of related d ...
