“follower” wrote in with yet another cool project for the Android Open Accessory SDK. This time, you don’t even need to do any Android programming; your Arduino Sketch tells follower’s Android app what to do and what to display on the screen: [via]

Handbag makes it possible to create Arduino-based accessories for Android devices without creating an Android app. You both define the Android application user interface and implement the behaviour in your Arduino sketch.

Here’s an example of how you would (currently) create an interface with a label, some space and a single button:

configureWidget(UI_WIDGET_LABEL, ID_NONE, “Example Handbag Android Accessory”);
configureWidget(UI_WIDGET_LABEL, ID_NONE, “”);
configureWidget(UI_WIDGET_BUTTON, ID_B1, “Toggle Digital Pin 4″);

Mike Colagrosso created Avviso, a Processing and Arduino library for sending push alerts to iOS devices using the Prowl API. This would make projects such as Snail Mail Push Alerts a much easier task because a PHP web server is not needed in the set up. The libraries, example code, and set up guide are available on Github.

This is a cool project with comprehensive explanations helpful for newbies. [via]

Not long after the Open Accessory Kit was announced, romfont posted a great set of instructions on getting this work with a standard Arduino: [via]

A lot of people have been put off by the price of the reference hardware kit, which is roughly $390. What’s worse, they appear to be sold out until end of May, and Microchip’s cheaper ($80) alternative doesn’t arrive until July. So instead of waiting I decided to write a guide on how to get an ADK-capable Arduino for about $55.

Google’s open accessory development kit on standard Arduino hardware, not confirmed but seems like it should work… [via]

A lot of people have been put off by the price of the reference hardware kit, which is roughly $390. What’s worse, they appear to be sold out until end of May, and Microchip’s cheaper ($80) alternative doesn’t arrive until July. So instead of waiting I decided to write a guide on how to get an ADK-capable Arduino for about $55.

Since the ADK reference design is based on Arduino and Oleg Mazurov’s excellent USB host shield, it stands to reason that we should be able to build our own hardware kit from these components. I already had these parts lying around from my work on MicroBridge, so I decided to ‘port’ their code, which in reality means just changing a couple of pin definitions.

That was fast… [via]

Android ADK project that shows the Artist and Track info for the song your Android device is playing from the new Music Beta service from Google. The sign gets the current track metadata from the new Android Music App. The spectrum analyzer animation is just eye candy — it’s not analyzing the audio…yet

Teague Labs has developed a device for programming and altering the code on Arduinos without the need for a computer. This opens new opportunities for in the field programming and testing of Arduino projects. [via]

The Computerless Arduino consists of two major components; an Arduino-compatible microcontroller loaded with a realtime code interpreter, and a stand-alone 5 button LCD display to display port values and manipulate code. The display can be connected to the Arduino via a 4-pin port at any time to peek at In/Out values, view the current code, and make changes as desired.

The experimental code for this device is open source and available on Teague Labs website.

Google picks Arduino for Android Open Accessory “kit”… [via]

From the beginning, Android was designed to extend beyond the mobile phone. With that in mind, we’ve developed Android Open Accessory to help developers start building new hardware accessories that will work across all Android devices. We previewed an initiative called Android@Home, which allows Android apps to discover, connect and communicate with appliances and devices in your home. We also showed a preview of Project Tungsten, an Android device for Music Beta to give you more control over music playback within the Android@Home network.

A USB micro-controller board that is based on the Arduino Mega2560 and Circuits@Home USB Host Shield designs (now referred to as the ADK board), which you will later implement as an Android USB accessory. The ADK board provides input and output pins that you can implement through the use of attachments called “shields.” Custom firmware, written in C++, is installed on the board to define the board’s functionality and interaction with the attached shield and Android-powered device. The hardware design files for the board are located in hardware/ directory.

…This is the Arduino board for Android OS (2.3.4 or later) to connect I/O. This item is The same model which is devlivered by Google in USB session of Google I/O 2011. All software are working with this boards set. http://a.android.com/demokit Contents in box RT-ADK 1 RT-ADS 1 microUSB cables 2 Please download software from above URL. RT-ADK、RT-ADS main feature CPU: AVR Base mode: Arduino with USB host function

MIDI Rainbow from SuLuLab on Vimeo.

Here’s a MIDI keyboard interface project from SuLuLab. It uses an Arduino, MIDI Shield, addressable RGB LED strip based on chip HL1606, 5VDC 1.5A PSU for strip supply (USB port current is not enough), and the Arduino’s FastSPI_LED library. [via]

MIDI messages from the keyboard (real or simulated on PC) enter the MIDI Shield’s MIDI IN and are presented to the Arduino serial port. The Arduino firmware interprets the MIDI messages NoteOn NoteOff, associates each key on the five octaves (60 keys) keyboard to a strip LED and lights it with color associated with the note. In the firmware to control the strip we used the FastSPI_LED library that allows you to address every single LED and turn the desired color (R, G, B).

For more details and to download firmware see the SuLuLab website and scroll to bottom of page for English version.

Keypads are everywhere; on your cellphone, on your TV remotes, on your stereo and now on your Arduino. Wait…. Why do you want a keypad on your Arduino? Well it’s a pretty useful device to input numbers and letters (example: telephones), it can also be used for security measures like a keypad door lock, and it’s prefect when you need a low-cost and accessible interface for your next idea. After all, It wouldn’t be practical to use a single button or a potentiometer to input your Pin on an ATM. So for this tutorial, we will be going over Sparkfun’s 12 buttons keypad (0-9, #, * ), and get you all set up with some code and schematic too.

Here’s a good video from Kevin Darrah for those new to GPS basics demonstrating how to interface the Parallax GPS module with the Arduino. Note that while this video is based on the discontinued PMB-248 module, Parallax indicates that their current PMB-688 module is pin compatible (as far as TTL interfacing is concerned) and will function as indicated in the video. (The main difference between the two modules is that the PMB-688 lacks the RS232 interface pins found on the PMB-248.)
