Functionally, the conditions are identical

You give up on reading characters as soon as there is nothing more to read.
That doesn't seem a reasonable approach, IMO

Typically, for any  serial link, you'll be limited to eight bit packets, so nine bits of data will result in twenty bit periods of air time.
16024  Using Arduino / LEDs and Multiplexing / Re: RGB LED SMD wiring question on: December 04, 2011, 03:00:44 pm
The only analogue pins are inputs.
Not a good place to wire an output device.
Use a PWM pin.

Common anode goes to +5v, each cathode goes to pin via resistor.

Maybe your Arduino will last until Christmas.
Maybe not.
16027  Using Arduino / Programming Questions / Re: trouble creating multidimensional array on: December 04, 2011, 01:29:55 pm
How big do you think
Code:
sizeof(char_array[i])
is going to be?

Perhaps if you posted your code, we could help.

I don't know what "pmw" is, but don't try driving your servo with PWM, use PPM instead.
16030  Using Arduino / Motors, Mechanics, and Power / Re: a problem with servo motor "Help" on: December 04, 2011, 08:09:08 am
Yes, that one looks ok, in that it is not a continuous rotation motor, but I can't say if it will work for you because only you know the specification you Ned for your application.
Be aware that metal geared servos are much more expensive than plastic geared ones.

It will go to, and hold, at the required angle.
However, don't expect the value written to correspond exactly to where the output shaft ends up pointing.

I have no idea what a ball and beam project is, so I'm afraid I can't help you.
16033  Using Arduino / Motors, Mechanics, and Power / Re: a problem with servo motor "Help" on: December 04, 2011, 07:27:35 am
That's what we call an ex-servo.
It isn't possible to command it to a particular angle, without the addition of some sort of encoder.
16034  Using Arduino / Motors, Mechanics, and Power / Re: a problem with servo motor "Help" on: December 04, 2011, 06:58:00 am
Do you have spec for this device, or is it a continuous rotation ex-servo?
16035  Using Arduino / Programming Questions / Re: Continually re-entering setup() on: December 04, 2011, 04:41:31 am
I think I'd avoid the RAM-gobbling strings like "Commenced device-under-test debugging!" (see the comment about candles and gas leaks), but yes, a useful technique.
