Make a 8×10 L.E.D Matrix using arduino

Leave a Comment / Using Arduino / By Tech Master

UPDATE 1: I HAVE ADDED THE CODE FOR CONWAY’S GAME OF LIFE UPDATE 2: NOW YOU CAN SAVE SOME ARDUINO PINS WITH THE HELP OF 1 SHIFT REGISTER. In this instructable I will show you how to build a quite fancy 8 by 10 L.E.D matrix(with scrolling text and animations) using the Arduino and 4017 decade counter. This type of matrix is easy to make and …

Arduino Knight Rider

Leave a Comment / Using Arduino / By Tech Master

In this tutorial, eight LEDs are interfaced to the Arduino Uno board. This is not complicated – it is just like interfacing a single LED to the Arduino as done in tutorial 3, but eight times over. A program is then loaded to the Arduino that will turn the eight LEDs into a “Knight rider” …

How to build an 8x8x8 LED cube and control it with an Arduino using arduino

Leave a Comment / Using Arduino / By Tech Master

There are a lot of LED cubes on Instructables, so why do another? Most are for small cubes consisting of 27 or 64 LEDs, rarely larger since they are limited to the number of outputs available on the microcontroller. This cube will be 512 LEDs, and will only need 11 output wires from the Arduino. …
