Intel® Galileo – Intel® Galileo is the first in a line of Arduino-compatible development boards based on Intel architecture.
Galileo is a microcontroller board based on the Intel® Quark SoC X1000 Application Processor, a 32-bit Intel Pentium-class system on a chip. It is the first board based on Intel® architecture designed to behardware and software pin-compatible with Arduino shields designed for the Uno R3. Digital pins 0 to 13 (and the adjacent AREF and GND pins), Analog inputs 0 to 5, the power header, ICSP header, and the UART port pins (0 and 1), are all in the same locations as on the Arduino Uno R3.
Now there is an Intel based Arduino – Intel Galileo - [Link]

This little project will demonstrate how you can build NEC protocol based Infrared Remote Control to use with various NEC Protocol IR receivers. actually there are lots of projects out there to accomplish this task but i have to write my own code because of too many requests on this IR(infrared) Remote Control Relay Board with PIC 12F675 Microcontroller people keep asking “Where is the Transmitter for this” although you can use any NEC protocol based remote ,but i just wanted to build one by my self. so here it is.

This tutorial is an introductory tutorial on getting started with the MSP430 series of controllers by Texas Instruments. muaz @ zeroohm.ae writes:
There are millions and trillions of ways to start using microcontrollers. Hobbyist or people who find hard to code normally prefers Arduino as their coding environment, while engineers might prefer using AVR/PIC. The MSP430 microcontroller is an extremely versatile platform which supports many applications. With its ability to consume ultra-low power it enables the designing engineer to meet the goals of many projects. It has, of course, its limitations. It is inclined mostly towards low energy and less intensive applications that operate with batteries, so processing capabilities and memory, among other things, are limited. However it’s still called a mixed-signal processor and is capable of doing some sort of speech processing. Before starting with some exposure to hardware and software part, I assume that you all have some sort of programming knowledge in embedded c. Even if you know java or c++, you will still be able to adapt to the tutorials easily as the logic will remain the same, only the code language changes.

FTDI introduces on the market technology EVE – complete graphic solution suitable also for slower microcontrollers.
Paraphrase with the woman´s name is very near to a name of a new technology of display control – EVE – embedded video engine. Company FTDI as a well known producer of USB solutions with a slogan USB-made-easy, decided to bring this philosophy even to a field of graphic solutions. The first representative of a new family is the FT800 graphic chip, containing all necessary to create a powerful graphic output. Perhaps the biggest advantage of this solution is, that „EVE“ puts only minimal requirements on the speed (and resources) of a Host processor, that´s it can cooperate even with smaller „low-end“ microcontrollers (Atmega, PIC, 8051,….) with a very small power consumption.
The essence of small requirements for a Host processor resides in a fact, that FT800 contains al functional blocks necessary for graphic operations and control of the display itself like:
● graphic controller with a clock (timing) generator
● touch panel controller
● frame buffer
● memory (registers, ROM, RAM)
● graphic processor and co-processor
● MCU interface (I2C, SPI) and other blocks.
Moreover FT800 also contains an audio module (synthesizer and a DSP sound processor with DAC) thus FT800 also provides a sound output (mono).
Besides a significant simplification of a graphic output is the idea of „EVE“ also based on a fact, that it has to enable a cheap production of a graphic output for a target device. According to an example from FTDI (displayed on an attached picture), it´s possible to simply build a powerful „display“ for the price of under 19 USD (at a volume production). At the same time this solution lowers requirement for a count of components (BOM) and also for a PCB space. Graphic capabilities of a new chip are really impressive as it features even such properties like anti-aliasing (subjectively sharper image even on a low resolution display), alpha blending (shading, 3D,…) and built-in complex pre-defined shapes and tools. All programming of FT800 is object-oriented, so for example drawing of a simple bargraph takes only 5 commands. To create a graphic user interface (GUI), the user initializes an object memory (up to do 256 kB) and then controls specified objects and their attributes. The result is the above-mentioned low load on a Host processor.
Only a brief description of all technical features would take a few pages, that´s why we rather recommend you to look at the attached video, FTDI EVE presentation, and to study FT800 datasheet. Further information will provide you documents FT800_Programmer_guide, AN_240_FT800_From_the_Ground_Up and AN_252_FT800_Audio_Primer. For a development support, there are also available various evaluation boards of the VM800 series. Guide price of the FT800 is 2,75 USD (100 000 pcs).

techunboxed.com has a designed a simple build of Arduino board.
Arduino clones are ubiquitous. A quick web search or a look at any electronics hobbyist website will turn up some kind of Arduino-like microcontroller board. Studies have shown that the absolute last thing the world needs is another Arduino clone that adds nothing or very little to existing designs. One might surmise that these are the exact reasons why someone should never design another Arduino clone, yet here is Ktuluino.
There’s nothing original or particularly compelling about the Ktuluino. The name even has “ino” added to the end which has become so overused that it’s often painful and cringe inducing. With seemingly everything going against it, why would someone make something like this? The answer is… this board was an exercise in PCB design. I need stuff to practice on, and although there’s nothing revolutionary about this board, it is practical. Who can’t use another Arduino, or three?

Saelig Company Inc. (www.saelig.com) has introduced new Warrior Modules containing the complete electronics required for joystick, mouse or I/O functionality via USB. Based on the successful Warrior USB-interface ICs, these new boards accept analog inputs in the range of 0V to 5V, are compatible with most joystick sensors, and also facilitate measurement, sensor, and other I/O applications.
Warrior ICs from Code Mercenaries are a family of universal I/O controllers for USB that handle all USBʼs complex protocol details without needing Windows drivers since Warrior ICs appear to the OS as HID Device Class (Human Interface Device). This means that Warrior ICs are controlled without screen-prompting for additional software – standard system drivers allow access to Warrior ICs directly from application programs. (A Linux driver is also available.)
Need to connect simple devices to a computer, like relays, switches, or a small display, but the computer has no parallel port or that port is in use by some other device? Using USB used to mean that you had to develop specific code for a USB-enabled microcontroller, developing a unique driver with lots of documentation and using expensive development systems. Using USB to serial adapters is not a good option either, since the adapters don’t have much intelligence and require a lot of programming.

Seven segment LED displays are known to be resource and power hungry. But because they are visually so charming and readable from a far viewing distance and at a much wider viewing angle as compared to any other electronic displays, they are still hugely popular. The required number of I/O pins to drive the LED segments can be reduced significantly by using an additional dedicated hardware. For example, the MAXIM’s MAX7219 device allows you to interface 8 pieces of seven segment LED modules using only 3 I/O pins of Arduino or any other microcontroller.

A great introductory tutorial about Arduino. randofo @ instructables.com writes:
An Arduino is an open-source microcontroller development board. In plain English, you can use the Arduino to read sensors and control things like motors and lights. This allows you to upload programs to this board which can then interact with things in the real world. With this, you can make devices which respond and react to the world at large.
For instance, you can read a humidity sensor connected to a potted plant and turn on an automatic watering system if it gets too dry. Or, you can make a stand-alone chat server which is plugged into your internet router. Or, you can have it tweet every time your cat passes through a pet door. Or, you can have it start a pot of coffee when your alarm goes off in the morning.

Analog Device’s AD8232 is an integrated signal conditioning block for ECG and other biopotential measurement applications. It is designed to extract, amplify, and filter small biopotential signals in the presence of noisy conditions, such as those created by motion or remote electrode placement. This design allows for an ultralow power analog-to-digital converter or an embedded microcontroller to acquire the output signal easily.
The device can implement a two-pole high-pass filter for eliminating motion artifacts and the electrode half-cell potential. This filter is tightly coupled with the instrumentation architecture of the amplifier to allow both large gain and high-pass filtering in a single stage. An uncommitted operational amplifier enables the creation of a three-pole low-pass filter to remove additional noise. The user can select the frequency cutoff of all filters to suit different types of applications. [via]
