Serial Port?

Hi, I’m pretty new to arduino. I got my photocell light/dark sensor to work last night then the Arduino program froze, I hadn’t saved, and now after doing everything I had done before, it doesn’t work.

Here’s a big problem, it wants me to choose the correct serial port BUT the arduino program won’t let me choose any serial ports. The ‘Serial Port’ drop down is grayed out and I can’t choose it.

Any thoughts?!

What OS are you using?

Do you have the FTDI Virtual Comm port drivers installed?

I have Mac OS X Version 10.4.11 with the 2 GHz Intel and I have installed the FTDIUSBSerialDriver_v2_2_9.dmg

If you type:

ls /dev/tty.*

in the Terminal, what output do you get?

Is the BT board powered? What if you try re-pairing it with the computer?
