The Ciseco SRF shield instantly transforms any Arduino style board into a fully wireless device. There are no jumpers to worry about, no configuration to be done, simply plug in and begin coding. The shield utilises the world’s best value, secure wireless module, the SRF.
You can securely exchange data with all other Ciseco radio devices, including the ultra-long range ARF. Designed for ease of use, the shield uses normal ASCII when transferring data, requiring no library or complex software. This means all your memory space is for code, not to drive the radio. All settings can be accessed or changed via standard text based AT commands.
The shield has extra pads to allow for configurations such as; Over the Air Programming of your micro, low power sleep states and adding an external antenna to extend the range.
The SRF has flexible frequency and power settings, to cater for all global radio regulations; these are easily set in software.

Ultrasonic range finder using 8051 microcontroller has been already published by me in this website. This time it is an ultrasonic range finder using arduino. HC-SR04 ultrasonic range finder module is used as the sensor here. The display consists of a three digit multiplexed seven segment display. This range finder can measure up to 200 cm and has an accuracy of 1cm. There is an option for displaying the distance in inch also. Typical applications of this range finder are parking sensors, obstacle warning system, level controllers, terrain monitoring devices etc. Lets have a look at the HC-SR04 ultrasonic module first.

Printoo’s flexible modules provide the ideal form factor to quickly create first product concepts for smart wearables devices. BITalino (http://www.bitalino.com/) is revolutionizing DIY health tracking by making physiological sensors to measure the body’s biosignals accessible to all. Combine the two and it has never been easier to create revolutionary smart wearable concepts to life.
With Printoo, a number of inputs were already available: accelerometer, temperature sensor, capacitive and light sensors. BITalino’s modules for Electromyography (EMG), Electrodermal Activity (EDA) and Electrocardiogram (ECG) can be easily connected to Printoo through a flexible coupling board. Combine these inputs with flexible LEDs (in strip or matrix form), electrochromic displays, a sound buzzer, as well as Bluetooth Low Energy connectivity, and the possibilities are endless.

This week FTDI Chip have announced a range of Arduino-compatible development platforms to support the company’s Embedded Video Engine (EVE) technology. The VM800P series provides engineers with everything necessary to implement Human Machine Interfaces (HMIs) featuring display, audio, touch elements and data processing aspects too.
The units can be programmed using the standard Arduino IDE (using a pre-programmed Arduino-compatible bootloader). In addition to support for various Arduino libraries, every VM800P incorporates an FTDI Chip FT800 EVE graphic controller IC and its FT232R USB interface IC as well as an ATMega328P 8-bit microcontroller running at 16 MHz. Also featured are a touch-enabled display LCD panel, a backlight LED driver, an audio power amplifier and a micro speaker. A choice of 3.5, 4.3 and 5.0-inch display formats is available which have precision fitted bezels to enable operation in industrial environments. The VM800P units also have a USB serial port for firmware upload and application communication, a battery-backed real time clock (RTC) for carrying out system timing and a micro SD socket loaded with a 4GByte SD card containing sample applications.

WatchDuino is an open hardware project that combines inexpensive electronic components and a complex Arduino (C++) code to build a useful and reprogrammable smart watch.
The code and the components have been optimized after a lot of prototypes to provide a rich set of features with a small and cheap battery that can last more than a week without recharging. A lot of electronic and software engineering was required to make this project possible.

Possibly the smallestest ATtiny85 based ‘duino derivative.
Recently, Olimex anncounced the Olimexino 85s, claimed to be the “World’s smallest Arduino ever“. Now, that looks like a challenge. I guess it is about time to show off what has been on my desk since some time last year: The Nanite, pictured below.
I designed this board for fun after the Digispark and, subsequentally, the Adafruit Trinket were announced. The motivation was to have my own ATtiny85 based development board based on a USB bootloader and optimized for the ubiquitous 170 point mini-breadboards. In contrast to the Digispark it even sports a reset button. However, it lacks an integrated voltage converter as it is supposed to be powered by USB.

This watch, by Jonathan Cook, recently won MAKE’s Arduino Challenge, as posted on Bits and Pieces from the Embedded Design World. [via]
The watch is the latest iteration of an ongoing BLE watch endeavor Cook has been exploring for the past nine months. In addition to time and date functionality, he’s building interfacing that any smartwatch wearer would want — email, Facebook notification, Twitter updates, etc., and hopes to have the community further the platform as well.

I belong to a village of Odisha, India where frequent power cut is very common. It hampers the life of every one. During my childhood days continuing studies after dusk was a real challenge. Due to this problem I designed a solar system for my home on a experimental basis. I used a solar panel of 10 Watt ,6V for lighting few bright LEDs. After facing lot of hardships the project was successful. Then I decided to monitor the voltage, current, power & energy involved in the system. This brought the idea of designing an ENERGY METER.I used ARDUINO as the heart of this project because it is very easy to write code in its IDE and there are huge numbers of open source library available in the internet which can be used according to the requirement.I have experimented the project for very small rated (10Watt) solar system but this can be easily modified to use for higher rating system.

Instructables user Slomi posted this useful project on how to build a wireless indoor and outdoor thermometer using an Arduino! Via Embedded Lab.
This Arduino-based wireless thermometer uses two Arduino boards to measure indoor and outdoor temperatures. The outdoor Arduino board sends out the outdoor temperature measured by DS18B20 sensor to the indoor Arduino board using inexpensive 433MHz RF transmitter and receiver modules. The indoor Arduino board then displays the indoor and outdoor temperatures on a character LCD display.
