Or, ça faisait un bout de temps que j’avais un R2 qui traînait dans les cartons… Ce petit bonhomme là : Ouais, la photo est dégueulasse, mais elle est […] Moving Forward with Arduino – Chapter 18 – RGB LED Matrix.

An "up/ down" counter, binary, and switch bounce This is one of a collection of pages which, together, attempt to show you "everything" about the Arduino's programming language. There is a page for you with more information about the project in general, and the way these pages are organized, if you want that. Please visit my page about power browsing notes sometime. Peggy 2LE Light Emitting Pegboard kit.
Peggy 2 LE is a smaller version of our "Peggy 2" light-emitting pegboard display.
Peggy LE 2 provides a quick, easy, powerful and efficient way to drive a lot of LEDs-- up to 625-- in a matrix designed for 5 mm LEDs. You can make an LED sign for your window, a geeky valentine for your sweetie, one bad-ass birthday card, freak the holy bejesus out of Boston, or instigate the next generation of low-pixel-count video games. Your call. It's a versatile, high-brightness, Arduino-compatible LED display. How you configure it and what you do with it is up to you. The display can run off the included ac adapter, and is designed to drive as many LEDs as you care to solder into the holes. Kit Options and Configurations This is an open-source project. What's New in Peggy 2LE? The main differences between the two are: Peggy 2LE is smaller-- about 1/4 the size, designed to fit smaller LEDs. Peggy Planner. Peggy 2.0 + Quartz Composer = Video Peggy!

Peggy 2 « Dual Elephants. I had such fun writing the simple ‘snake’ game for my peggy 2 that I wrote a bunch of other games for it as well.
At the moment there is Snake, Breakout, Pong and Race. You can download the sketch as peggy2_games_0.1.zip When compiled it takes up 11432 bytes (it includes the ‘Tone’ library as I have started adding sound to the sketch – connect speaker to ADC5 to hear it) Starting peggy2_game When you turn on the peggy2 a menu is presented displaying the available games – you can select from them using the up/down buttons and select with the ‘select’ or ‘any’ button on the left of the peggy2. Playing the games Snake When the game first starts you can choose which level to start at. Eat the ‘apples’ to get points, don’t hit yourself or walls Arrow buttons control movement of the snake. Pong Hit the ball back, get a point if the AI misses, AI gets the point if you miss Left/right buttons control movement of the bottom paddle (one player only for the moment) Break. Bionic Arduino – Introduction to Microcontrollers with Arduino. Bionic Arduino is a set of four 3-hour classes in November 2007 hosted by Machine Project and taught by Tod E.
Kurt. It is an introduction to microcontroller programming and interfacing with the real world using the Arduino physical computing platform. It focuses on building new physical senses and making motion with the building blocks of robotics, using Arduino as a platform. In the class, participants are shown and experiment with the Arduino’s capabilities and learn the basics of common microcontroller interfacing, such as: digital output to control lights and LEDs, digital input to read switches and buttons, analog output to control motor position or LED brightness, and analog input to read sensor inputs. Playground - I2C. PlanetArduino. Controlling 500 LEDs with PWM - Electronics and Robotics - Stack Exchange.
I am the author of the ShiftPWM library and I just updated the documentation to include schematics and a lot more general info for normal LED's, LED strips and high power LED's.
You probably already started your project, but since this page gets a lot of visitors, I'd still like to provide a detailed answer. If you want to control 500 LED's with ShiftPWM, you can get about 64 brightness levels per LED at 60 Hz. You would use 64 shift registers. Dedicated hardware PWM drivers will give you more brightness levels, but will be a bit more expensive. I think the main advantage of my library is ease of use, because it includes RGB and HSV functions and a lot of examples.
I would personally go for the TLC5916 of TLC5917 instead of normal shift registers, because they have a built in constant current LED driver. On my website ( ) I have more info on how to connect the LED's and how to deal with driving the long signal wires with the Arduino at high speeds. LEDMatrix : MondoMatrix. Click images to enlarge Description The LEDMatrix is a MondoMatrix expansion board that can control up to 64 tri-color RGB (4pin) LEDs.
The board can also be used to control 192 individual LEDs. Each LED can be controlled to have a degree of luminance between 0 and 255.
