"There are two CPU in our project, ATmega328 and ATmega1284. We set up the wireless communication by two Xbee chips. One of them connects with ATmega328 working as the transmitter to transmit the signal, another one is connected with ATmega1284 to be the receiver. We pick up ATmega328 to be our transmitter part because there is a microphone on it which could receive and store the voice signal from people."

"In just a few hours of hacking and experimenting, we turned this radio-controlled car into a WebSocket-controlled car. Don’t worry, no actual cars (or bunnies) were harmed in the making of this demo, as you’ll see as we walk through the hardware and software we used."

"My wireless temperature probes work by using an Xbee module to transmit readings from a TMP36 down to the Arduino base station…these take a voltage of around 3-5.5V as input and will output a voltage between 0-2.7V to indicate the temperature, which can be from -40 – 125°C."

"The Gloves are a cutting edge experimental gestural music ware being developed today for the purpose of Imogen Heap’s studio and stage work. Using a unique gestural vocabulary, motion data-capture systems, and user interfaces to parameter functions developed by Imogen Heap and her team, artists and other users will be able to use their motion to guide computer-based digital creations."

"The Science Tricorder Mark 2 was a wonderful adventure of discovery to develop. It’s my pleasure to be able to share it with you…..The Science Tricorder Mark 2 was planned during Spring 2008, and actively developed starting August 2008 until December 2010 — largely over my fourth and early fifth years of graduate school."

"This little project will demonstrate how you can build NEC protocol based Infrared Remote Control to use with various NEC Protocol IR receivers."

"Here we show a little Theremin module which plugs onto a Arduino Board that gives out the tune to a speaker or puts out the tune as control signal like MIDI, Servo etc. We were using this device not only as a musical instrument, various kinds of proximity sensors, pointing devices or as interface in combination with Processing, Max or Pd have been build with this technique."

&quotA while back I built a mobile-controllable home automation system, and promised to blog it. It’s taken a while, but here it it…DIY Home Automation via WAP and the Web–How-to."

"I’ve talked in at least 1 other post about how to use the Infra Red remote control of a toy helicopter for other projects : once the protocol reverse engineered, it’s very easy to program a micro controller to listen to it and I find it very useful to integrate this into any project that needs some wireless remote controlling."

"The most straightforward approach to this would be to take apart an existing remote and fire its button with a microcontroller. However, that didn’t sound like much of a challenge, so instead the goal became to train the micro to output the signals itself."
