Make sure that you have installed an unzip/unrar program on your pc. (winrar/winzip)Step 1: Download the filesStep 2: Go to your download folder and extract the files to a folder called Main (case sensitive)Step 3: Right click one of the files for instance: Breakout.ino and open it with the arduino IDE.if this doesn't work you could try to open the IDE and drag the files over.Step 4: Upload the codeExeption 1: if you get a message wich informs the files have to be in a specific folder just press ok and the arduino IDE should do it for youPlease report back if you have any issues or if you have already tried this.
If my latest reply results in nothing, please try to download the 1.8.1 version of the arduino IDE and try it again.Download here: https://www.arduino.cc/en/Main/OldSoftwareReleases#previous
** a folder called main
Have you added all the libraries?
they are all .ino files, you have to place it in a folder called main and just open it in the IDE
I don't exacetly understand what you're aking but the download for the arduino code is somewhere in the instructable, just open it in the ide and upload the Main.ino file. But make shure that you have installed the libraries and they are also in the instructable somewhere. If you have any more questions please ask me.

No problem thanks for making it clear
One question: does the programmer matter when burning a bootloader, because you have it set to AVR ISP...
I don't really understand, for the HC-05 you take power from the arduino but you ground it ad the triple-a battery pack. am I missing something? because it seems like there would be no flow of electricity anyhow great project
Also in you're schematic you ground a servo on the power rail...
