LCD Text Display for XBee

Bookmark and Share

Words are how humans communicate. An inexpensive LCD text display can be the most economical way to make your project talk to people, and it’s easy to make a wireless one with an XBee radio.

Build this example using an LCD with a serial backpack, like this one  from Adafruit, or this one from Sparkfun for inexpensive wireless text output. It’s the fastest way for your project to gain human communications!

Now you can create a Twitter display for your office door, prototype a quiz game toy that teaches math, or add interactive instructions to your automated greenhouse watering system. This LCD-enabled XBee is a great way to make the things you make talk to people!

Joystick for XBee Example

Bookmark and Share

Join a joystick to your XBee radio for a terrific way to add movement to your projects, sending anything you like in different directions. You can achieve full wireless control of household robots, industrial equipment, safety cameras…even stratosphere-seeking weather balloons. Set about inventing a new class of cat toys or create a new way to interact with museum exhibits. Maybe you’d like to make an interactive lawn sprinkler that waters your name in the grass? Here’s a terrific way to control it! This tutorial walks you through the easy way to connect an Adafruit Small Arcade Joystick to your XBee.

The video below shows the joystick connected to a group of four wireless LEDs. You might want to try controlling stepper motors to create directional movement, orchestrating water pumps into a casino-style fountain or harvesting crops from the comfort of your porch swing. Start building one today!

Say it Proud with XBee Panel Meter

Bookmark and Share

Want to impress your date? Make a muscle measuring love meter! Or perhaps you’re a business genius and prefer to quantify your cash. Either way, you’ve got to have a panel meter to indicate your achievements. The latest tutorial from Digi’s XBee Examples & Guides shows all the steps for creating a wireless readout. You’ll push your project’s needle towards “11.” It’s also great for giving your device a retro feel. More on that from the site:

As the world of technology becomes increasingly digital, the nostalgia for older analog technology grows. The panel meter is a great piece of analog technology that can be easily integrated into your projects. And thanks to the XBee 802.15.4 radio’s digital to analog converter, you can make a wireless panel meter with only a few components.

This video demonstrates the panel meter in operation, using a light sensor to control its movements. You could also monitor remote radiation, track the temperature in refrigerated trucks or keep an eye on your favorite stock by connecting it to the Internet with the XIG. Go ahed, make yourself a meter!

XBee Example: Making Money with a Coin Acceptor

Bookmark and Share

Earn some income using this latest XBee Example that shows how to easily connect an XBee radio to one of Adafruit’s nifty coin acceptors. It’s part of our efforts to document how to create all kinds of interesting XBee inputs, outputs and interconnections.  We’d like to make making things easier.

Here’s what the site has to say:

“Your XBee can make real money, all by itself! This easy-to-use coin acceptor can be part of any project where you want to accept coins, whether they be Euros, pence, pounds, a Cambodian Riel or American quarters.

“The XBee radio will send a signal every time a coin is inserted into the acceptor. In this tutorial, we’ll walk you through how to program the radio, configure the acceptor and wire it up to an XBee so you can create projects that earn real cash!”

The video below shows an XBee coin acceptor in a basic, local implementation. It’s just a starting point for you to get creative. For example you could also hook everything up to the Internet via the new XBee Internet Gateway and start Counting Money with a Coin Acceptor online!

XBee Example for Feeling the Force

Bookmark and Share

The newest tutorial on Digi’s XBee Examples site teaches you to create a wireless force sensor or FSR. The force sensor sends out a signal that varies depending upon how hard you press on it. It can be used to measure weight or pressure.

Additional examples for XBee radio sensors and outputs are being posted regularly, all summer long. Follow our RSS feed to collect ‘em all. For example last week’s Digital Input example could be used to detect whether a cat is on a mat. But if you need to know how fat is that cat on the mat, then then Matt Richardson’s new Feeling Force example is for you!

XBee Internet Gateway Released for Macintosh, Windows and Linux!

Bookmark and Share

Connecting your XBee to the Internet just got simple. The new XBee Internet Gateway v1.5 runs directly on Windows, Macintosh and Linux computers! All you need is a single XBee with USB adaptor to put entire XBee networks online. With the XIG, you can turn any XBee into an Internet sensor module, create web-controlled motors , online indicator lights, and stream online data to and from any Arduino. Both 802.15.4 (Series 1) and ZigBee (Series 2) XBees are supported. You could create giant sensor networks, analyze and control distant equipment, scrape gossip from Facebook or simply flip switches in your own home!

The XIG is a software gateway that makes it easy to connect Digi’s XBee radios to the Internet. It is able to send data to any web app and can also be linked to the iDigi device cloud for full remote configuration of every radio in your network. Here’s how to get started:

  1. Download the XBee Internet Gateway for Windows, Macintosh, Linux or ConnectPort
  2. Read the XIG documentation including installation instructions
  3. Give us your feedback!
The XBee Internet Gateway is a free, open-source project written in Python. It was initiated by Rob Faludi and extended by Jordan HusneyTed HayesTom CollinsMichael Sutherland and other generous contributors. We’re pretty happy to offer it for free to you!

New XBee Examples Site

Bookmark and Share

Our brand new XBee Examples project site just went live! Check out  the first tutorials that Matt Richardson and I’ve published on Digi’s instructional library site:

Right now I’ve got a big pile of different sensors, lights, motors, scent emitters and more on my desk. We’re going to demonstrate XBee hookups for ‘em all, then show how they can be linked to one another, hooked up to computers and connected to the Internet. From breathalyzers to joysticks and from wind sensors to air fresheners we’re creating a modular toolbox that should jumpstart all kinds of creative and practical XBee projects. Come and see the beginnings:
