Rainbowduino Sign using Arduino

The Rainbowduino is a variant of the Arduino and among other things is capable of driving an 8x8 RGB LED matrix. I had just finished a backyard re-model and was in need of an entrance sign. Step 1: Carving and Painting the Sign I had recently acquired a CarveWright CNC wood carving machine. It's a pretty nice piece of equipment and comes with some pretty easy to use design software. Then you just print out ...

Potentiometer or variable resistor control LED Code

The if() statement is the most basic of all programming control structures. It allows you to make something happen or not depending on whether a given condition is true or not. It looks like this: if (someCondition) { // do stuff if the condition is true } [Get Code] There is a common variation called if-else that looks like this: if (someCondition) { // do stuff if the condition is true } else { // do stuf ...

48×8 SCROLLING MATRIX LED DISPLAY USING ARDUINO CONTROLLER

A monochrome (single colour) LED dot matrix display is used for displaying the Characters and Symbols which is interface with a microcontroller. This project will deliberate on displaying a scrolling text message on a 48×8 LED dot matrix display. The microcontroller used is Arduino Uno which is open source prototype Electronic platform. The 48 columns of the LED matrix are driven individually by six shift r ...

LED Show using Arduino Esplora

This example shows you how to read the values from the joystick. The output will be displayed through the serial monitor and as a color on the RGB LED. The joystick has two axes, X and Y. Each axis controls a color of the RGB LED: red with the X-axis, and green with the Y-axis. The brightness of the blue element will be controlled by the position of the linear potentiometer. Circuit Only your Arduino Esplor ...

Arduino 4x4x4 LED Cube

Overview: This instructable will cover the building process of an 4x4x4 LED Cube. I will be using an Arduino to control the LEDs.  Since the Arduino (Freeduino) has a total of 20 pins (including the analog pins) we will not need to have any multiplexing or shift registers.  I will take you though what i did in order to build the cube and create some designs of your own. Step 1: Bill of Materials Bill of Mat ...

Color Changing Night Light with ATtiny using Arduino

I wanted to create something for my wife as a present and this is what I came up with. This is a dark activated color changing night light. It has a sensor that can tell when the room light is turned off. This then will light a RGB LED and slowly fade through different colors. Its brains is a ATtiny85, but you could also use an Arduino.  We have little boys that would appreciate this on at night. Step 1: Pa ...

LED Dot Matrix Display using an Arduino

In this project, you shall again use two sets of shift registers. These will be connected to the rows and columns of the dot matrix display. You will then show a simple object, or sprite, on the display and animate it. The main aim of this project is to show you how a dot matrix display works and introduce the concept of multiplexing because this is an invaluable skill to have. Step 1: Things Required for t ...

Traffic Lights Beginner Arduino Project

This is a beginners project for the Arduino. I am using the Arduino Uno but should work with little or no modification on other arduino models. Setting up the hardware is very easy. This project is more of a training tool for learning how to program a timer list while listening for a button press. Parts you will need. - Arduino - Solder-less Breadboard - 10 LEDs --- 2 Red --- 2 Yellow --- 2 Green --- 2 Smal ...

LED Hat Display with Pong using an Arduino

A while ago, as my first microcontroller project, I made a Pong game on a 5x7 LED display, but then nothing became of it. Recently I was given a hard hat as part of a uniform (for an engineering competition) and told to customize it, and remembered pong. In this instructable I will show you how to make a scrolling LED display and how to install it in a hard hat. It also plays pong! LED_Diaplay_Code.zip91 KB ...
