The Arduino ADK R3 is a microcontroller board based on the ATmega2560 ( datasheet ). It has a USB host interface to connect with Android based phones. It is compatible with Android's Accessory Development Kit examples. It has 54 digital input/output pins (of which 14 can be used as PWM outputs), 16 analog inputs, 4 UARTs (hardware serial ports), a 16 MHz crystal oscillator, a USB connection, a power jack, an ICSP header, and a reset button. The ADK is based on the Mega 2560 .

Did You Win Yet? » Android Garden Monitor
Overview One of the coolest things announced at this year’s Google I/O was the Android Open Accessory Kit , which allows Android devices to interact with accessories over USB. As an attendee, I received the Arduino-based ADK DemoKit board, which I’ve used to build an app to monitor my Aerogarden . HardwareThe Accessory Development Kit (ADK) is a reference implementation for hardware manufacturers and hobbyists to use as a starting point for building accessories for Android. Each ADK release is provided with source code and hardware specifications to make the process of developing your own accessories easier. Creating new and alternative hardware based on the ADK is encouraged!

AVR Development Boards, Have Fun with Microcontrollers, $9.60
This board allows you to quickly build Microcontroller circuits for 28 pin AVR Microcontroller such as ATMEGA8, ATMEGA48, ATMEGA88, ATMEGA168 and ATMEGA328. One half of the board is dedicated to the microcontroller, whilst the other half resembles our standard prototyping layout and can be used to build your circuits. The board supports a 10 pin ISP connector to program your microcontroller, a reset button, external oscillator and a low pass filter for AVCC.
Automatic Electricity Usage Measuring Device | HACKOLOG - Amazing Hacks and Mods
Want to make something interesting and at the same time useful? Then why not try to make a device that would automatically measure the amount of electricity consumed on a daily basis . Read on to know more about this. There are several methods available that can be used to perform this activity. One way is to place current measurement coils on the mains.
A few folks asked me about the Liquidware BeagleBoot SD Card , and if there was a tutorial somewhere showing them how to do it with an SD card they had laying around at home. So in the spirit of open source, and because it’s Friday, I present my step by step guide to making your own boot SD card for the BeagleBoard … Step 1 – What’s going on here? First a summary of what’s about the happen. The gist of the steps that follow are this: you start with an SD card… and then you’re going to download Liquidware Beagle Angstrom Linux, format the SD card in a specific way that helps the BeagleBoard know where to find the boot image, untar the rootfs, and untar the kernel into separate partitions on the SD card.

Sip'n Puff Ipod Dock
Sip'n Puff Ipod Dock Here is an example using the Sip'n Puff Arduino shield to make an Ipod dock. The Sip'n Puff Arduino shield is currently a Kickstarter project . If you like this project and would like to see more products like this one, please support our project on Kickstarter and tell all your friends about it.[Updated Jan 25: Correction! There is a 1.8V voltage source on the Beaglebone: Port 9 Pin 32. Thanks to Koen Kooi for the info. I've updated the text with this information] [Update May 5: In kernel version 3.2.14, the file system path for the analog pin readings was changed from /sys/devices/platform/tsc to /sys/devices/platform/omap/tsc] This article is my second explaining the fundamentals of coding with the Beaglebone .

The Arduino meets Processing project intends to make it as easy as possible for anyone to explore the world of physical computing. All you need is an Arduino board as well as the Arduino and Processing software, which you can download on their project websites. On this website we explain how to: set up electronic circuits with various kinds of sensors, control and measure the sensors with the Arduino board, send the data to the computer, and use the received values to generate computer graphics with Processing. For all examples you need some basic electronic equipment such as a breadboard , resistors, the sensors, and some wires.

Here’s a fun hack we’ve been experimenting with — a computerless Arduino! It’s small, inexpensive, and doesn’t require a computer to change the code, so you can take it with you and make awesome things anywhere. 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. By keeping the display separate, it’s possible to have many dedicated Arduino modules (we’re using one of the smallest, cheapest, and most-capable Arduino clones, the Teensy2.0 for $18), without needing to spend much on each additional device. For the display we’re using the super small uLCD-144 (by 4D Systems for $29), and the system could easily be modified to use a larger display or computer if desired.

• Versatile, programmable robot tank kit • Onboard LiPo battery charger • Complete Arduino board built-in (Arduino Uno) • Dual H-bridge and onboard voltage regulator (only one battery needed) • Compatible with a variety of shields • Two XBee areas ( XBee headers sold separately) and solder prototyping area • No soldering required The DFRobotShop Rover V2 – Arduino Compatible Tracked Robot (Basic Kit) is a versatile mobile robot tank based on the popular Arduino Uno microcontroller. The Rover uses the popular Tamiya twin motor gearbox and the Tamiya track and wheel set. The DFRobotShop Rover PCB incorporates a standard Arduino Uno (surface mount ATMega328), L293B motor driver (connected to pins 5 to 8), voltage regulator and prototyping area while contributing to the mechanical structural of the robot. The onboard voltage regulator allows the entire board to be powered using as little as 3.7V to ~9V*. The onboard LiPo battery charger can be used only with the following batteries:

An ARM-based Arduino is the next step in the development of this open source platform, but it isn't all gain. The whole world seems to be going in ARMs direction. The latest version of Windows 8 will run on ARM processors and now the open source Arduino platform has a new member - the ARM-based Arduino Due announced at the Maker Faire in New York.
