226  Using Arduino / Installation & Troubleshooting / Re: arduino and Ipad on: April 29, 2012, 05:10:35 pm
The answer to ALL of your questions is no.
227  Using Arduino / Project Guidance / Re: directory structure - I give up on: April 24, 2012, 07:11:38 pm
In the Arduino IDE, click on File -> Preferences, look at the "Sketchbook location:" at the top. It will look something similar to this (C:\Users\admin\Documents\Arduino)  Inside that directory is where you put your libraries folder, and inside that libraries folder is where you put new libraries.  So in the example case above, your libraries folder would go in C:\Users\admin\Documents\Arduino\LIBRARIES.  The libraries directory under the Arduino-1.0 is NOT where you put new libraries.

Take a look here:
229  Using Arduino / Installation & Troubleshooting / Re: Serial port 'COM6' already in use. ┬áTry quiting any programs that may be... on: April 21, 2012, 01:10:58 am
Unplug the USB cable, wait about 15 seconds then plug it back in.  Make sure that nothing else is accessing the COM port.  Reboot if those fail.
230  Using Arduino / Project Guidance / Re: Plant watering system with a Seeedstudio solenoid valve on: April 14, 2012, 10:54:52 pm
Both of those should work just fine with Arduino.  See this for information on using the solenoid with Arduino.

Look here for information on using the hall effect water flow sensor with Arduino.
231  Using Arduino / Installation & Troubleshooting / Re: Arduino Crashes on Mac OS X 10.7.3 (lion) when uploading to Uno on: April 11, 2012, 10:38:02 am
What version of OS X did you upgrade from?  And how did you upgrade?  Directly from AppStore, burned DVD, thumb drive?
232  Using Arduino / LEDs and Multiplexing / Re: multiple LED's in SERIES one output on: April 09, 2012, 05:10:10 pm
Horizontal and vertical are subjective depending on how you are viewing your breadboard.

On your breadboard, excluding the rows of power rails (the red and blue lines), the rows that are identified by letters are NOT connected together, the columns that are identified by numbers ARE connected together.  Each column of 5 holes are connected together, the long rows are NOT connected together. 
233  Using Arduino / Programming Questions / Re: Ethernet Shield on: April 09, 2012, 09:24:44 am
Try the ASCII Table sketch under Examples -> Communications.  Load the sketch with nothing attached to the Mega2560.  Open the serial monitor and see what happens.  It is very unlikely, though not impossible, that the Mega2560 is actually on COM1.
234  Using Arduino / Installation & Troubleshooting / Re: "Could not create java virtual machine" on: April 07, 2012, 11:41:24 pm
Go here and make sure that Java is functioning on your system.
235  Using Arduino / Sensors / Re: Ultrasonic Anemometer on: April 02, 2012, 12:13:42 pm
Is there also English information available on the website?
236  Using Arduino / Installation & Troubleshooting / Re: Lost ability to open IDE on my desktop on: March 31, 2012, 08:41:35 pm
Check the task bar for running programs, or just restart.  Most likely something is running in the background that needs your attention, and that is why you are getting the ding.
237  Using Arduino / Project Guidance / Re: broke my uno trying to power 4 amplifiers through 4 mosfets on: March 29, 2012, 10:49:11 pm
If you want complete optical isolation, connect "Vcc" to Arduino +5 volts but do NOT connect Arduino Ground.  Remove the Vcc to JD-Vcc jumper. Connect a separate +5 supply to "JD-Vcc" and board Gnd. This will supply power to the transistor drivers and relay coils.

If relay isolation is enough for your application, connect Arduino +5 and Gnd, and leave Vcc to JD-Vcc jumper in place.
238  Using Arduino / Installation & Troubleshooting / Re: Can't connect Arduino to PC on: March 26, 2012, 02:24:35 pm
Have you disabled the bluetooth connectivity?
239  Using Arduino / Installation & Troubleshooting / Re: Windows doesn't recognize Arduino on: March 26, 2012, 02:07:43 pm
Did you test your board on your friends computer?
240  Using Arduino / Installation & Troubleshooting / Re: Arduino Mega 2560 REV3 on: March 26, 2012, 01:08:44 am
Glad that you got your rev 3 board.  I prefer mail order myself from reputable, established Arduino dealers.  I have also succumbed to the desire to "have it in my hands now" that keeps RadioShack in business though.
