in thread LED blinking Morse code from Raspberry Pi

As mentioned already: yes, the RPi can run one of several Linux distributions. I've run Arch Linux before; currently a version of Debian is on my RPi. The OS is stored on a SD card, which can also act as storage.

The standard "Raspbian" install comes with Perl, and I've used CPAN to install modules (such as the package I mentioned).

I posted this code because I've just discovered how to use the I/O pins to read or write data to/from the outside world, with Perl, on my Raspberry Pi, and I'm excited!

    Yeah, me too. I guess now the next step would be to get some opto-isolation relays, are be able to send messages out via the LEDS. Then, see if and ports give a varying output, say 128 or 256 voltage levels, then you could use it to provide realtime feedback for controls. After watching the various youtube videos on the newer anti-gravity experiments, it may be that the only way to get one, is to build one yourself.... and I'm dreamin of using the Raspian to do the Hall effect sensor and stabilizer functions. I need to get back to my home world. :-) Get me my Imhotep's flying platform!
