Hi,
I was playing with your sketch and the HC-05 module, under linux mint and it works quite fine, thanx for sharing.
To turn HC-05 in AT command mode, I first didn't succeed because I didn't follow the power on steps ... (was too excited to test)

So I wired gnd of HC-05 to pin8 instead of gnd of Arduino and added these two lines to your sketch in setup() after "digitalWrite(9, HIGH);"

pinMode(8, OUTPUT); // pin8 from Arduino to gnd of HC-05
digitalWrite(8, LOW); //to power it on AFTER setting pin 34 HIGH and without "playing" with wires

Now, just pluging my duemilanove thru usb and everything works like a charm.
Hope this will help others

Keep going on the good work !

Amongst a Tubleweed Mine Sweeper, and Tree Bark Foam, you will find an Arduino embeded on a Tego Technik for RC, here: http://faz-voce-mesmo.blogspot.pt/2012/11/caca-minas-rolar-espuma-de-casca-de.html
