Hmmm... I got one servo running from external power on pin 9, but the code I tried to write (newbie programmer here) doesn't seem to work. I looked at the reference library on the Arduino website too.

Thanks. It works fine with 6. 

Will a battery holder that can hold 6 batteries work with only 4 inside?

It's cool. Here's where I am right now... I built the hand itself, but I need to get multiple servo's running at once, so I can tie the strings on the fingers into the holes in the servo motor and I'm having some trouble getting 1 to run on external power.

This is all so confusing, but it has to get done...

Wait a second... How do I add a servo? Here's the line of code.

  // attach the servos
  for(int nServo = 0;nServo < CONNECTED_SERVOS;nServo++)
  {
    myServos[nServo].attach(SERVO_TO_PIN(nServo));
  }

This is getting out of hand... I'm doing everything it says in this tutorial, (http://rcarduino.blogspot.com/2012/04/servo-problems-with-arduino-part-1.html) and it still isn't working... I have to have this thing done by February 4th, and this is worth a TON of points, so if it doesn't get done, my grade will suffer...

Woops. I actually meant the ON LED. 

Yeah, that's what I'm talking about. It started working again though.

The Arduino.

However, one of them did die on me. Whenever I plug the USB in, the green LED turns on and then immediately turns off. 

Nevermind. It was a false alarm. 

I also have an extra that I haven't touched at all and that isn't working either.

So I tried to do sweep with my Uno, and it decided that it does not want to work anymore, so now I have to do a completely different science project.

Alright. I'll keep that in mind.
