There are any number of projects for which it would be handy to animate LEDs from a PC. Not a microcontroller, but a full-on PC. Media — music and video — are a natural for PCs, and tools like Max/MSP and Processing are a natural for creating media-based software sketches. (We use “PC” here in the generic “personal computer” sense, not in opposition to Mac; Using a combination of Processing and Arduino, everything shown here runs as well on Mac or Linux as it does on a Windows system!)
As a first demonstration, we’ll build a simple “Ambilight ” clone. Ambilight is a feature of some Philips televisions that projects colored light onto the wall behind the display , synchronized with the content on the screen to create an immersive effect. The authentic Philips system is well-integrated into the TV and works from any video source. Our facsimile, being computer-driven, works specifically with media content from your PC. This means its perfect for watching Youtube, TV or Movies on your PC or playing games!

There’s more than just one 32-bit PIC based “Arduino-compatible” on the block and this one, the Pinguino, is a board that I was pretty interested in – mostly because it’s from a maker (for makers) not a company so much and the efforts towards an open source tool chain. I emailed the designer and maker of this board asking about its history, the differences between their board and the chipKIT Uno32. Keep reading for a fantastic overview with Jean-Pierre Mandon and Tsvetan Usunov.

Arduino 1.0 bringing improvements and changes.. David writes – [via]
Arduino 1.0 is coming soon. The first release candidate was posted to our development site for Maker Faire NYC and is available for public download. It brings a number of improvements and changes to the software that we encourage you to test before the final Arduino 1.0 release, scheduled for the end of the month.
The Arduino development environment (IDE) has undergone a number of adjustments…

RGB LCD Arduino Intervalometer @ The Custom Geek. [via]
I am getting ready to sell some kits and wanted a good way to photograph the assembly without fumbling around trying to hold a camera in one hand and a project in the other. The answer? An intervalometer. A device that can send an IR signal to my Nikon, triggering the shutter. The video above explains all of the features including; automatic delay calculation, auto stop, multiple LCD and LED feedback options, Li-Po charging, FTDI headers, and manual control via button or plug-in foot switch.
This project will work with most Nikon DSLR cameras without changing anything, but can easily be adapted to work with Canon, Sony, or any camera that will accept an IR remote.

This is chapter forty-two of a series originally titled “Getting Started/Moving Forward with Arduino!” by John Boxall – a series of articles on the Arduino universe. The first chapter is here, the complete series is detailed here. Any files from tutorials will be found here.
This will be the first of two chapters that will examine another useful form of input – the numeric keypad; and some applications that hopefully may be of use. Here is the example we will be working with:

We needed to collect a list of Arduino libraries for some prep work for the Arduino team’s 1.0 launch. We currently have 25 Arduino libraries!

To understand why the PPT can increase the efficiency of your solar power charging system a closer at the electrical characteristics of a solar panel is necessary. Solar panels convert photons from the sun striking their surfaces into electricity of a characteristic voltage and current. The solar panel’s electrical output can be plotted on a graph of voltage vs. current: an IV curve. I represents the current in amps and V represents the voltage in volts. The resulting line on the graph shows the current output of the panel for each voltage at a specific light level and temperature. (Fig. 2) The current is constant until reaching the higher voltages, when it falls off rapidly. This IV curve is applicable to the electrical output of all solar panels.

For the second year in a row we decided to announce our new products at Maker Faire in NYC.
Tomorrow morning, if you come to the Arduino tent, you will be able to see:
Arduino 1.0, we finally froze the Arduino API, the IDE and the layout of the boards. We’ve made some minor additions to the Arduino connectors to make them more flexible. Tomorrow you will be able to download the release candidate and in 1 month of frantic testing with the community, the platform will be ready and stable.
Arduino Leonardo, a low cost Arduino board with the Atmega32u4. It has the same shape and connectors as the UNO but it has a simpler circuit. On the software side it has a nifty USB driver able to simulate a mouse , a keyboard, a serial port (with more drivers coming later). As usual for Arduino, everything will be released as open source (Core, Bootloader, Hardware).
Arduino Due, a major breakthrough for Arduino because we’re launching an Arduino board with a 32bit Cortex-M3 ARM processor on it. We’re using the SAM3U processor from ATMEL running at 96MHz with 256Kb of Flash, 50Kb of Sram, 5 SPI buses, 2 I2C interfaces, 5 UARTS, 16 Analog Inputs at 12Bit resolution and much more.
Instead of just releasing the finished platform we are opening the process to the community early on. We’re going to be demoing the board and giving away some boards to a selected group of developers who will be invited to shape the platform while it’s been created. After Maker Faire, we will begin selling a small batch of Developer Edition boards on the Arduino store (store.arduino,cc) for members of the community who want to be join the development effort. We plan a final and tested release by the end of 2011
Arduino Wifi Shield. It adds Wi-Fi communication capabilities to any Arduino. Instead of using any of the classic WiFi modules on the market we wanted to have something that will provide the maximum level of hackability to the user. The shield is based on a wifi micro module made by H&D Wireless coupled with a powerful AVR32 processor that carries the full TCP-IP stack leaving room to add your own protocols and customisations. We’ve also worked hard to make sure that you will be able to migrate your code from the Ethernet Shield with minor changes.
We’re also going to show some prototypes of new platforms we’ve been working on: We have robots, new IDEs and more.
It has been a crazy few months and we want to thank ATMEL very much the support that we got on all the new products.
Come over to Maker Faire and have a look for yourself!

Using PWM outputs with an Arduino and a LED @ The Custom Geek. Jeremy writes… [via]
Hi everyone, been a while since my last post, but I have been a busy new daddy. I wanted to demonstrate what PWM output was and how to use it nicely in a sketch. I’m really big on ramping lights on and off (my entire house is set up that way) and would like to share how do accomplish that. I also wanted to use a video to show PWM outputs on a scope to help me explain the process.

I have been waiting for an excuse to use a Nyan Cat in a blog post and the ‘ST7565 Negative LCD Display’ released by Adafruit being equipped with RGB LED backlights was the perfect occasion. After all, RGB LEDs can create a ‘rainbow’, right? All that’s needed is a cat to go with it and Voila!
