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.

Chris from PyroElectro has posted this tutorial on interfacing with XBee.
Getting started with XBee can be tricky, even though it shouldn’t be. Here is a drop-dead simple guide to using XBee modules out of the box. The tutorial shows you how to build a wireless interface with XBee modules between two PIC 18LF4520 microcontrollers.

Converting an Arduino to 3.3V – All official Arduinos run on 5 volts, which for a long time was the ‘standard’ voltage for hobbyist electronics and microcontrollers. But now the coolest new sensors, displays and chips are 3.3V and are not 5V compatible. For example, XBee radios, and SD cards and acellerometers all run on 3.3V logic and power. If you tried to connect to them with 5V you could damage the internals of the accessory. We use chips like the CD4050 to do level conversion but if you are using a lot of 3.3V devices, maybe you’re just better off upgrading the entire Arduino to run from 3.3V! To do that, we will replace the regulator so that the DC barrel jack for a 3.3v type, and then reconfigure the 5V usb power line so it goes through the regulator as well.

JeeLabs has a product known as the JeeNode v5, which is essentially a miniature Arduino (Atmega328p) board with an onboard RFM12B wireless module. Boards are available with the serial interface (shown above) as well as USB.
While it’s not an Xbee compatible RF unit, the RFM12B has its own RF12 library of functions which should help you accomplish many control and data transfer tasks.

The present document shows step by step how to easily build an interesting pointing device: the wireless tilt mouse, that allows to control the mouse’s cursor on the PC screen through the tilt of the board itself. The analog data from a 3-D accelerometer and from two push-buttons are acquired, converted and radio transmitted by an XBee module using the standard ZigBee protocol.

For the second Carlitos’ Project, I wanted to do something a bit more “useful” than pretty lights. So I decided that a speech controlled Arduino robot should be interesting enough as a project.
For this project, I used the DFRobotShop Rover (a mobile Arduino kit), the VRbot speech recognition module by Veear, two XBee modules, an Arduino Uno, two XBee shields and some other components. see the video below to learn how to do your own.

Logos Electromechanical LLC Announces the Zigduino, a Shield-Compatible Arduino Clone with Built-in Wireless
SEATTLE Wash. – Feb. 23, 2011 – Logos Electromechanical LLC announced the Zigduino, an Arduino-compatible microcontroller platform that integrates an 802.15.4 radio on the board.
The radio can be configured to support any 802.15.4-based protocol, including ZigBee, Route Under MAC/6LoWPAN, and RF4CE.
The Zigduino uses a reverse polarity SMA connector (RP-SMA) for an external antenna. This allows the user to use nearly any existing 2.4 GHz antenna with it. The Zigduino runs on 3.3V, but all I/O pins are 5V compatible. Read the rest of this entry »

Build yourself a wirelessly controlled, Arduino-powered message board!
Here’s an easy project which creates a wirelessly programmable message board. It uses XBee modules to provide a wireless serial link between your computer and the device. You interact with it via a simple menu system. There are no buttons (other than the reset button, which is hidden) on the device.
