Ok  -I found wiring.c and commented out the cli statements, but that didn't help.  Any other suggestions?

Great  -I'll try that to fix it.
Silly question though. I am using IDE 17 and don't have those folders anymore. Where exactly do I find wiring.c?

Thanks.

Hi,
I am trying to use a WiShield from http://asynclabs.com/home and a LCD with a Duemilanove and IDE 17.  Separately they both work fine.  Together the shield does not tweet successfully. I have  changed the pins, so I believe there is no conflict there.  
The problem seems to be when I add line LiquidCrystal lcd(4, 3, 8, 7, 6, 5);  As you can see the shorter response from Twitter does not result in a finished Tweet.  I have tested this several times and I get the following:

With line LiquidCrystal lcd(4, 3, 8, 7, 6, 5);

I believe the LiquidCrystal library is causing the problem.
Does anyone have any suggestions?

Thanks guys.  I found one at Adafruit as well.

Hi,
I'm using an Duemilanove to power some sensors and a 16 x 2 LCD, but  the LCD screen is using to much power and I want to power it with a 9 volt battery.  I have been using the 5 volts from the Arduino.
What is the best way to externally (not from the Arduino) power a HD44780 16x2 LCD without frying it?

Thanks

Hi,
Anyone know an easy way to write to a log file?
I'm using a Deumilanove with a WiShield and trying to figure out why I stop sending tweets.  I'm currently connected via USB to a MAC.
How do I write to a log file, not just print to the serial monitor?

Thanks.

Awesome, I'll ignore this message.  

thanks.

Hi,
Has anyone used the Audio Shield from Adafruit?
I'm using version 15 of the Arduino software.
I can't get the AFWave library to load.  I get the following error.

fat16.cpp: In function 'fat16_file_struct* fat16_open_file(fat16_fs_struct*, const fat16_dir_entry_struct*)':
fat16.cpp:603: warning: only initialized variables can be placed into program memory area
Any help is appreciated.
Thanks.

Hi,
I had to switch computers to a Dell running XP.
I downloaded the drivers and it now reads the Arduino fine.
However when it starts receiving actual data, I get the following error.

Anyone know how to fix this error?
What does ss is denied mean?
Any help is appreciated.  Thanks.

Thanks.
No, never had to do this before with my OSX 10.5 computer.
Which driver do I need for OSX 10.4?

# VCP Drivers
# D2XX Drivers

The OSX 10.4 machine is the G4 tower.  
How do I install and or check the drivers?

As far as I know the machine is up to date in terms of the latest OSX 10.4 software updates.

Hi,
I'm running Processing connected to Arduino with a USB cable.  Basically the Processing sketch listens for input from a sensor connected to the Arduino and then calls a PHP page to send an email. With OSX 10.5 using port 2 it works fine. Moved it to a G4 Tower running OSX 10.4 and had to change the port to either 0 or 1.  Not getting any sensor readout from either port on the OSX 10.4 machine.  How can I get the sketch to work in OSX 10.4 without upgrading to 10.5?

Cheers.

Hi,
I am thinking of buying a Mac Mini that I can leave running for various projects around my house.  One project may be triggering an Arduino based sensor that then takes a photo when I'm not home via a webcam.
I'm looking for a small cheap computer that I can hook various projects to and then leave alone.  

Is the Mac Mini a bad idea?  Any other suggestions?

Thanks

Hi,
I'm almost done with my LM35 temperature sensor project and need to make an on & off switch.  What is the best way to do this?
Do I put the switch on the positive side or the negative side?
Also is there a way to turn the entire Arduino on & off if using a wall plug that will always be plugged in but not easily accessible?
Cheers
