That's cool. Incidentally, I'm building something related (incorporates node, Twilio, and Roving Networks WiFly). We launched a Kickstarter that did not make funding <a href="http://www.kickstarter.com/projects/daisyworks/internet-your-thing-0" rel="nofollow">http://www.kickstarter.com/projects/daisyworks/internet-your...</a> but I am continuing to build it out. It monitors sensors and alerts you when conditions are met. You can also control the RN WiFly to drive GPIO through the web browser using node, redis and SocketStream on the backend. The hardware we built also allows you to plug in an Atmel/Arduino with more sensors - so you could do things like drive a servo from your browser/phone, or control a robot.
Great work! I don't have any experience with node.js but this looks very cool, and I love that you can just call it up.<p>From your writeup:<p>>This code is mostly self-documenting, however the one area that confused me starting out was that you need to open a Serial port in order to use the WiFly module.<p>>The one possible issue to note is that you cannot use the Serial monitor or the Serial.print commands because the WiFly has taken over the usual port.<p>If this was causing debug headaches for you I would reccomend checking out the NewSoftSerial library by Arduiniana[1]. It allows you to turn any digital pins on the Arduino into a UART serial (RX/TX) setup. I use it all the time with Bluetooth or Xbee projects. If you are using Arduino IDE 1.0 it's actually already included, you don't even have to donwload the library, it's called just "SoftSerial" in the library menu I believe.<p>[1]: <a href="http://arduiniana.org/libraries/newsoftserial/" rel="nofollow">http://arduiniana.org/libraries/newsoftserial/</a>
If anyone has any other Twilio/Arduino tutorials they would like to see, please let me know! I'm working on another one at the moment but am always open to suggestions
Would be interested to know how much power those servos are pulling from the Arduino. The regulator on the Uno is fairly limited in power output and there's also the WiFi board to power as well.<p>Did you experience any problems with crashes on the Uno because of a lower power condition?
Great one ! Thanks a lot !! Could you tell me how to connect some Input device like UI Screen with Arduino and get touch inout from it? Any links will be helpful!!
