256  Using Arduino / Installation & Troubleshooting / Re: Compiling error with no error msg on: March 12, 2012, 07:26:40 pm
Seeing the code would be the first step to trying to help figure this out.  I know that you checked it - but I have checked my own code before and missed something.  A fresh set of eyes is always a good thing.

You definitely need a breakout cable or board to program the Freeduino Lite.

Straight from the Freeduino site "...easy programming connection via FTDI Breakout cable or Bhasha's own USB breakout board"

The only time that I have seen OS X only show the CANCEL option when choosing what program to open a file with was when a non-executable file was selected.

Make sure that you are clicking on the arduino application and not a zip or dmg file. 
259  Using Arduino / Installation & Troubleshooting / Re: Can't upload to arduino mega 2560 on: March 10, 2012, 03:01:53 am
Do you have any shields plugged in while trying to upload?
If so, unplug them while uploading.

Can you unplug the board, go to device manager >, then plug the board back in. Go to Ports (COM & LPT) > Arduino Mega 2560 (COMX), and make sure that it's showing the same COM port that the IDE is showing for the board.

If it is, try changing the COM port to a higher port as follows:

To do this: Close the IDE, go to device manager > Ports (COM & LPT) > Arduino Mega 2560 (COMX) > Right click > Properties > Port Settings > Advanced

There you can force the com port to any other one.  Generally a higher port works best.

Restart the IDE, change the COM port to match the one you set above, and try uploading again.

261  Using Arduino / Programming Questions / Re: wiring.h: No such file or directory on: March 05, 2012, 02:30:09 pm
Could someone please explain how to do this on a Mac OSX? Sorry I'm still new...

You would edit the Tone.cpp file using TextEdit, replacing each occurrence of wiring.h with wiring_private.h

Virtually all the code you need for the Arduino side is already out there, so the difficulty level depends on how much you know about web development.  If you look around, you will probably find most of the webpage code included with the Arduino samples as well. 

So, I would say the difficulty level is probably medium at most.  There are a lot of knowledgeable people on this forum, and I'm sure that if you post your questions in the proper places, you will be able to find the answers to any areas that may be difficult for you.

The data from the Arduino will be sent to the ethernet shield, which will send it to the webpage.  Your app will interact with the webpage.  When you make a change to a setting on the webpage using your app, the ethernet shield will see that change, pass it along to the Arduino, which will then carry out the instructions that you gave it from your app.

For instance, the Arduino might sense that your solar panel is pointing southeast.  The Arduino will send that information to the ethernet shield, which will post it on your webpage.  Your app will see that information on the webpage.  Lets say that you want the solar panel to face southwest for some reason. Your app would send a command to the webpage (this can be as simple as checking a box on the webpage), which will be picked up by the ethernet shield, then the ethernet shield will send that command to the Arduino, and the Arduino would send that command to the solar panel tracking system, which would point the solar panel to the southwest.

You don't really need to develop an app to control the Arduino through a webpage.  You can write the webpage so that there are check boxes for the commands that you want to have, then when you check one of those boxes, the webpage will send that command back through the ethernet shield to the Arduino.

Tell us what that is, preferably with a model/part number as well, and we can probably find the exact specs for it.

Back to your original question. The best way to go is to buy a book. Preferably the one I wrote called 'Programming Arduino: Getting Started with Sketches'.
A search on Amazon will find you all sorts of good C programming books and if you know C#, you will not find it hard. But you will end up writing code where function names start with a capital - curse you Bill Gates!
Books are distilled knowledge! Save yourself some time.

I second the acquisition of 'Programming Arduino: Getting Started with Sketches'.  I have learned more from that one book than any other.

The ethernet shield is certainly a web server.  It connects to your router, then it will serve it's webpage.  You would then connect to the website, and control the Arduino.

The arduino already has a usb port - that is how it communicates with the computer.

Here are a couple good links about stepper motors and arduino:

The best book I found to help with programming is "Programming Arduino  Getting Started With Sketches"  by Simon Monk.

A google search turns up several places that carry the max7221 at reasonable prices.  Do the search, then click on SHOPPING on the left side.

Your willingness to start small and then build up as you can will take you far.  Engineering demands inquisitiveness and resourcefulness - developing these traits at the beginning is going to be a boon for your career.
