I think that would be a good start.

Didn't know that this is working this way
Sorry, I assumed you were talking about analogue composite PAL/NTSC/SECAM style video.

If you are, get used to something like an LM1881

Like teletext, you send the data in BLANKING.

. Every tutorial i've tried makes the servo go a full rotation, how can i change that?
R/C servos rarely make a full rotation - they have mechanical stops which prevent this.
What code have you been using?

Very low bit-rate data in blanking?

What if brightnessRed goes from, say, 254 to 256 without ever equalling 255?

One is 3V, the other is 6V.
Both will probably work at 3V.
Neither can be driven directly from an Arduino I/O pin.

/code continues in the same way for Green and Blue which have the same issue.
So, scrap all the excess colours, concentrate on one colour, use some arrays and write some functions.

OK, servos are a bad choice for moving the robot, because they only move about 180 degrees or so.
But they may be a good choice for the Ping turret.

Steppers vs. DC motors depends a lot on how you want the robot to move, how much battery you want to carry, how many pins you want to dedicate to movement.

How are the servos powered?
16076  Using Arduino / Programming Questions / Re: Program slows down? on: March 03, 2012, 03:04:53 pm
No "loop?
No "setup"?

How are the servos powered?
(Why are you reading the pot twice?)

Is it voltage or current which concerns you?

will i need separate source to power the motors?
If this is a senior project, presumably you're a senior - what do you think?

Define "small" and "sensor"  (hopefully, you'll see where this is going)
