FamiLAB, Orlando's Community Lab or "Hackerspace" is offering an "Intro to Arduino" class on August 27th. Information can be found here: http://familab.org/blog/public-classes-events/

This class is for beginners, and we will (optionally) provide hardware for those looking to get started.

If you are in Orlando and already know the Arduino platform, we are looking for additional teachers / mentors for the class...send me a PM, or email us: classes at familab.org

If you want to learn more about FamiLAB, check us out at www.familab.org or come visit the lab - we have a monthly open house, and we are also happy to coordinate a personal visit.

If you are in Central Florida (Orlando), check out Orlando's Hackerspace - FamiLAB - www.familab.org

We do regular projects and competitions (like http://sensingplatform.org) using Arduino and will have our "Intro to Arduino" classes starting in August 2011.

If you want to discuss Arduino, work on a group project, or have an Arduino group meet, just use the contact form at www.familab.org/blog/contact

Hope to see you at the LAB,
Ian

I did something similar recently and used Processing and the Twitter4J library. I found an example on the processing site and had something working in a matter of minutes.

I chose to create my own terse serial protocol between the computer and the arduino, but you can also use the firmata library which can direct control the arduino from processing.

Processing is Java based, so it doesn't meet your desire to use C, but it would be a very quick way to get there if you don't mind a little java syntax.

The store says it is down for maintenance. What are the prices on the new boards?

I really like the yellow jacket concept...

Got my pico + protoshield this weekend. Very nice parts!

Nicely timed question as I'm about to do the same thing with a Gator+ board (power from external regulated power supply) - should I use the USB connector method vs. using the 5v pad then?

For date / time, check out the time library we discussed earlier - now you know how to build a custom message with the time once you get it off an internet server...

Glad it worked for you - you figured it out yourself, you just needed to know what was possible smiley

Another quick thought - You have a long delay there - I'd be concerned that I wouldn't catch the mailbox trigger signal. If you are worried about sending duplicate messages from the same signal, you might consider decreasing the delay (to increase polling frequency) and then use the millis() value to know how long it has been since your last tweet and don't send again if less than X millis since the last message was sent...

Check out the TextString library  - http://www.arduino.cc/en/Tutorial/TextString

There is an example with that library called "StringAppendNumber" that creates a string object, sets it to an initial value, appends a read from a pin (you would omit this part), appends the current millis and some ending text.

Suggest running that example by itself to see how it works, then modify it to create the message in the form that you want, then merge the working code with your existing code.

Simple version - use the millis() command, append that to the end of the message. According to the documentation, it repeats about every 50 days.

More cool - get the current time from somewhere on the web and append that to the end of your message. Check out the "arduino time library" in the playground for sample code.

2:Robotics, drone aircraft, a lot of different things, avid follower of ardupilot and the guys @ diydrones.

3: I reverse engineered the wii motion plus and have a few demos of that that are posted around, built a library to control the isobot robot, and have an awesome working bus notifier that works completely from the ethernet module to check bus position from gville's GPS website. And it can be accessed via txt message to twitter.

Cool stuff & fun projects! I just saw ardupilot for the first time the other day - looks like a great project for me and the boys smiley

Looks like good interest...

How about posting more info so we can put together an agenda...

1) What is your skill level / background?
2) What are you interested in?
3) What can you bring to show others? (Arduino related products or projects?)


For me:

1) In my first month of Arduino learning, but moving quickly smiley Long-time coder, great with basic electricity and circuits, but never built anything "complicated" until now.

2) I'd love to see GPS or Ethernet shield projects in person, or any of the miniature Arduino variants.

3) I have a nice new array of 9 ShiftBrites and an RTC module that would make for good demos...I also have a WaveShield & Arduino Mega although they are about to be semi-permanently mounted smiley

My current project is documented here: http://raisinggeeksandgearheads.blogspot.com/

I'm in Orlando, so if we can work out the scheduling (I'm in an MBA program, so I'm pretty scheduled), I can help with the logistics (location, etc.)

I'm in Orlando and would gladly host such a group.

I'm just completing my first major Arduino project which includes an Arduino Mega, a WaveShield, a 20x4 LCD, lighted buttons, analog gauges, a piezo siren, a strobe warning light, a shift (in) register and a joystick from an M1 Abrams Tank. It all comes together to form a spaceship simulator in my son's room.

My electronics background is weak (but improving quickly!), but I'm a long-time coder. My primary motivation at this point is to teach my son basic electronics and to see if he takes an interest in coding.
