Arduino and python-firmata

I just spent five hours trying to figure out why  none of the Firmata libraries for Python were working over my serial connection. I was wondering why the previous program remained on the board and none of the signals sent were hot.

Hint: you need to load Firmata first onto the board before it can understand the protocol. Oh. Duh.

Don't forget to load up "OldStandardFirmata"

Only “OldStandardFirmata” (Firmata 2.0) seems to work with my version of python-firmata. The newer Firmata PDEs can talk Firmata 2.1 and 2.2, but I’m too tired to figure them out.

That's it. What Next?
