We’ve updated our excellent character LCD tutorial to include a section about RGB-backlit LCDs, with wiring images, video and example code!

We created Matatino, a framework that lets you communicate between your Mac applications and your Arduino. You can follow our tutorials to get started with adding Matatino to your project.
To see Matatino in action, check out Meters for Arduino.
We will be adding more examples, libraries and tutorials for the Android ADK, iOS Redpark Serial Cable, Processing and OpenFrameworks in the future! You can stay informed about updates through RobotGrrl’s blog Apps4Arduino category feed.
Do you have a hardware project that you need some great software for? Tell us about it, and we would love to help you out!

Using VFD display with Arduino – [via]
Summer of 2010 I picked up an Arduino board from adafruit and took some time to walk through all of the tutorials available with it. Since then I have spent most of my time on other projects including my bachelor’s. Recently I have obtained the Motor Party Pack, LoL Shield Kit, and a 20×2 VFD (Vacuum Fluorescent Display) to go with the original board so my interest is sparked again. I have found that the Motor Party Pack and LoL Shield have adequate instruction and tutorials, but the VFD is lacking in beginner level instructions to get started. As such I have decided to write a tutorial for the 20×2 VFD available through adafruit.
The adafruit VFD is made by Samsung and is model No. 20T202DA2JA, this is really unimportant though as adafruit is nice enough to link you to the spec sheets for both the module and the controller chip. What you would be looking for is the pin-out found on page 4 of the module controller sheet.

Radio Arduino – uses Adafruit WaveShield!… [via]
What it is really doing is playing 24 music tracks that I preloaded onto an SD card in WAV format. There are also 10 tuning noises tracks that get played when the tuner is turned.
Because this is the first time I did this I had a lot of help. Firstly the chaps and chapesses at Hackspace have been very supportive in teaching me how to use and Arduino, particularly Adrian McEwan and Oomlout. Also Jingle Joe who supervised my soldering of the Wave Shield, Brox who helped me decipher the ancient mysteries of FAT16 and Esme who helped dismantle the original radio… PS I did do some of it myself!

Build a Netduino-powered Game Console. Fabien writes… [via]
Over the past few months, my friend Bertrand and I have been working on a game console, the PIX-6T4, which is powered by a Netduino mini.
The console is designed as platform for learning digital electronics and C#: we’re in the process of writing a book covering all aspects of building the console, how its components work and how to write games for it with our framework. Here’s a video of the prototype of the console…

Stian made this awesome sous-vide temp. controller, which he calls the “SousVide-O-Mator”. Built around an ATMega328 with the Arduino bootloader, it uses a DS18B20 temp. probe to monitor the temp, a 20×4 LCD to communicate with the user, and a solid-state relay to switch the rice cooker on and off. It also features one of the neatest, cleanest stripboard layouts I’ve ever seen (style counts!). He writes:
My brand spanking new homemade Sous Vide controller (PID controller for cooking). By connecting the relay to my rice cooker and putting the probe and a small aquarium pump inside I’m able to very accurately control the water temperature..
This is basically a heating immersion circulator as used by some fancy restaurants – readily made equipment cost in the range of $1000.. So I made one myself on the cheap (controller + rice cooker + water pump). This can be used to cook meat to perfection
Perfect for Sous Vide cooking! ( For more information about Sous Vide: http://en.wikipedia.org/wiki/Sous-vide )

HIDuino is a firmware package that allows you to easily implement MIDI over USB using a standard Arduino UNO. It has been out for several months, but this talk from NIME2011 elaborates on its history and how it works. Sadly, the audio cuts out around 7’20″, so after that you’ll just have to watch the slides. [via]
This paper presents a series of open-source firmwares for the latest iteration of the popular Arduino microcontroller platform. A portmanteau of Human Interface Device and Arduino, the HIDUINO project tackles a major problem in designing NIMEs: easily and reliably communicating with a host computer using standard MIDI over USB. HIDUINO was developed in conjunction with a class at the California Institute of the Arts intended to teach introductory-level human-computer and human-robot interaction within the context of musical controllers. We describe our frustration with existing microcontroller platforms and our experiences using the new firmware to facilitate the development and prototyping of new music controllers.

This is just a quick video showing that you can power an AVR project from a fried servo or an old emergency cell phone charger.

This is a simple power meter to analyze (with LabVIEW) the current consuming in a house using the led indicator of a house energy meter. Reading the red led of a home energy counters the system detects the correct consumption in a house. It is a noninvasive method, not cut wire, no current disconnects, so a very interesting method…
The system consists of two parts: the Arduino board that detects the led pulses and sends the data via the XBee module, and a PC that receive the data through a USB/Xbee module and processes the data with LabVIEW so you can prepare and study the consumption in a very instant. Arduino sends two data to the PC: 1 – Real time datas 2 – Average consumption measured in a time of 5 minutes.
