so when u kill your ATmega chip , you can pop it out and replace it with a new one
Check out the Roboduino, Arduino-compatible board!

That's it?
So if I'm using a breadboard I don't need it right??

all grounds should be connected together everywhere.
if you are using more than one battery pack in a circuit you will need to connect all grounds together.
your servo ground should definitely be connected to the GND on your 9v battery AND your 5v(regulated) GND.

i don't know the details of your circuit but 9V will be too much for your servos.
you will need to power then from a 5-6V source. (again make sure all the GNDs are tied together.)

Woot thanks mate!  ;D
I'm using a 6V for the servos and 9V regulated to 5V for the micro and digital inputs.

If you are going to use a 9v battery and regulate it to 5v you are gonna waste lot of energy and your regulator is going to emit a lot of heat.

I'm following the $50 robot tutorial  ???

you can use the 9V but I'm just saying that using 6V is more efficient.  ;)
