Would you like an LED bar graph to wirelessly show you how bright or dim a room is elsewhere? Well this is just the solution for you! This project uses an MBed microcontroller, light sensor, LED bar graph, and a pair of XBee radios to get you going on monitoring brightness without even being there.
Are you having a party? Would you like to be able to wirelessly control your disco ball’s revolution speed from afar? Then your solution is here! This project uses a set of XBees and an Arduino to control a disco ball’s lighting as well as how fast it revolves.
Do you want to be able to access GPS coordinates of anything, flying or not? Well, you can do just that by wirelessly sending that data to be seen from a computer on Device Cloud. This will use the Arduino microcontroller and XBee radio. After all, Arduino and XBee are best friends in the electrical engineering world! Why else would an XBee shield exist?
Would you like to be able to keep tally of a score on a portable LCD screen with wireless pushbuttons? Then this is the project for you! This project uses an Arduino microcontroller, Mbed microcontroller, and a couple of Digi XBee radios.
Would you like to be able to play automated Rock, Paper, Scissors electronically and wirelessly? Then this is the project for you! This project uses two Mbed microcontroller and a couple of Digi XBee radios to enable two people to choose a button representing either Rock, Paper, or Scissors and determines the winner on your own LCD screen.
Do you plan on flying a quad copter? Well, what if you could stream in data wirelessly?! Then you could replay your quadcopter in 3D motion and track its battery data over the course of your flight. This will mainly comprise of wirelessly connecting to the ardupilot mega (APM) quad copter through an XBee connection. One XBee will be connected to the computer and the other will be connected to the telemetry port on the quad copter. Follow the following wiki page for instructions on how to construct this: http://copter.ardupilot.com/wiki/xbee-radios/
Now that you have fully hooked up your XBees and quad copter, now we can talk about MavLink! MavLink is a software program that takes input data from the XBee and determines location, speed, GPS location, etc. for the quad copter. Follow the link for instructions on installing MavLink and follow the tutorial to learn about all the cool things it can do! http://qgroundcontrol.org/mavlink/start
When you start MavLink, your window should look like that of Figure 1.
Do you want to detect when a person passes by? Whether it is outside your apartment or your room or even in the next cubicle, you can now wirelessly detect if someone passes by which will sound a voice message and display a message on an LCD screen. This will use the Arduino microcontroller and XBee radio. After all, Arduino and XBee are best friends in the electrical engineering world! Why else would an XBee shield exist?
Do you plan on flying a quad copter? Well you’ll need a way to monitor your battery level! Otherwise, you will get excited and fly it and then the battery voltage will drop enough such that the current will drop and then your quad copter will crash and there will go hundreds of dollars to waste because you didn’t buy insurance. How about that landing? Would you like to have the power to switch a laser on to determine where you are in reference to the ground? No worries! We will create a device that wirelessly displays your current voltage level, status messages, an LED light that displays the battery percent remaining, and you will even have the power to turn a quad copter mounted laser on or off wirelessly with the control of a switch, all on one device using Arduino and Digi XBee radio technology. After all, Arduino and XBee are best friends in the electrical engineering world! Why else would an XBee shield exist?
