python cgi blink test

i wrote a simple hello world python script to make my Arduino blink an LED and write some text to the screen. The script works fine when i run it from the command line (./ But when i run it from my web browser as a cgi it displays my text, but won't blink the LED.

general question: Is it an issue with Apache2 running the script with a different permission for the tty/USB0 port?

any help here would be greatly appreciated.


... figured it out. I needed to change permissions on tty/USB0
