So I just successfully finished the $50 robot and I am now hungry for more!
The first thing I want to do is take my $50 robot board and start playing with the code to try to do some different things with my modified servo's and my photoresistor sensors.
When I built the $50 robot, I copied the project and followed the instructions laid out by Admin in the tutorial, everything worked well. I am able to build the project, and I am able to program the mcu.
So now I tried making a new project, but naming it something different, ServoTest.
Everything else I am doing pretty much exactly as Admin described.
The one thing I did do is modify the makefile to use the target ServoTest instead of Photovore_1
I wrote some simple code in the .c file in the source, I imported the SOR_utils.h file, and I tried to compile.
When i build, I am consistently failing with the error:
ServoTest.c:56:30: error: invalid digit "9" in octal constant
referring to the following line of code, which is taken directly from the photovore_v1.c which is working fine.
sensor_left=a2dConvert8bit(0829995);
Now, I am a developer, and I am interpreting that to mean that I am using a 9 in a constant that can only accept the numbers 0-8, I may be wrong.
What I don't understand at all is why this worked when I named my project photovore_v1, and why this is not working under a new project name.
I looked through the makefile, and I am not really seeing anything else.
can anyone help me out here?
Thx.

Everyone, sorry for this.
I figured it out, I actually removed the leading 0 and it worked.
I have no idea why this project required me to remove the leading 0, and the original one allowed it, but it is working now.
