(I know I didn't post them anywhere, and I trust that Jimbo didn't, either)

I said in an earlier post (Reply #45) that they weren't mine to distribute, when someone asked me to forward them, so No.

Haven't gotten any progress report from  JimboZA, either.

Progress report: I have stopped all Arduino / robotics activity.

Never mind. Sorry I asked now.

My question is answered.

Btw, not once did I use the word "problem".

Thanks everyone.

The Moral of the Story.... post all code not just the part where it seems the problem might be.

Quick and wasteful way would be a 7805 to step the 12 to 5, but better is to use something like this. EDIT... but look at how much current you need too. Also that 2120 is adjustable which is why I bought it- have a dig around at Pololu.

The problem is almost certainly caused by the fact that the function is defined within another one. 

Yep that's sort of what I was thinking: OP might have put this function just above the closing } of loop() for example....

Post the few lines above it..... I'm guessing a previous line wasn't terminated or something.

In this application, yes.

I'm having a good day: it's only 0815 here and I've learned two things already. By hometime I'm going to be bursting with new knowledge.

Oooo, so did I have that back-asswards? It's not to limit the current into the transistor, it's to limit the current out of the uC?
9  Using Arduino / Programming Questions / Re: Stuck in a simple function programming on: February 26, 2014, 01:04:20 am
Post a bit more (read as: all of your  smiley-cool )  code; the problem might be just above that function?
10  Using Arduino / Programming Questions / Re: Stuck in a function programming on: February 26, 2014, 12:53:25 am
Your return needs a ;

Code:
return InputData;
11  Using Arduino / General Electronics / Re: Why did they put this resistor here? on: February 26, 2014, 12:50:01 am
Afaik, it's to limit the current into the base.
12  Using Arduino / Programming Questions / Re: Coding an XOR on: February 26, 2014, 12:41:29 am
Yes Nick, but I meant as a sibling to the && and || ones, not as a bitwise operator.
13  Using Arduino / Programming Questions / Re: Coding an XOR on: February 25, 2014, 11:16:31 pm
I think that would still make sense, since XOR means only one, of however many inputs there are, is true.

Anyhoo, me off to work.... 0630 here, have to keep the wheels of commerce and industry turning.
14  Using Arduino / Programming Questions / Re: Making a DC motor change directions? on: February 25, 2014, 11:08:49 pm
Here's an easier way to code your XOR:

Code:
if ( ( (button1 ==HIGH) &&  (button2 == LOW) ) || ( (button1 == LOW) && (button2 == HIGH) ) ){
// do XOR code
}

(attrib: CrossRoads)
15  Using Arduino / Programming Questions / Re: Coding an XOR on: February 25, 2014, 11:06:30 pm
Ah yes, that's an easier way... I'll suggest that to the OP on the other thread.

But no built in "XX" as an XOR sibling to "&&" and "||"?
