Have we had "the dog ate my Arduino" excuse yet?

accel x,y,z: 184, -484, 14992

Before you go any further, you need to verify that gravity is working properly where you are.
Post code.

Use a guard dog. Name him "Arduino".

I'm fundamentally opposed to the kind of reforms proposed by "modeller".

I don't want a perfect micromanaged toy world.

I like the chaos and sheer unexpectedness of the forum as it is; it's like a rummage sale, or a parts bin, and someone with a completely different background and life experience will challenge your thinking.
Hell, software and hardware design requires rigid, methodical thinking, so it's good to come somewhere where you can encounter other people with a different outlook.

I don't want compartmentalisation.

If you want/need an Arduino forum just for toy trains, start one, but don't stunt the growth of this one.

I can't see how a bitwise and is useful.

in this particular case it should work as well as logical AND, but I agree it should &&

Have a look at the blink without delay tutorial, and substitute "micros()" wherever it says "millis()", and multiply the interval by 1000.

Majenko, your anti-AVR tirades/whines are starting to get tedious.
Cut it out, there's a good chap.

It has 32k program memory, aka ROM

@OP,the generic 'trick' is to sum the range of the values, and subtract the new value.
In your example, the range is -10 to +10, so -10 +10=0.
Now, say your accelerometer gives you -5.
0 - (-5) = 5.
Say it gives +3.
0 - 3 = 3.
Very simple arithmetic.

Dear AMPS-N,
When are you going to stop relying on the forum to do the most basic tasks, and start thinking for yourself?

Code:

byte i;
  for (i=0; i<6; i++) {

How quaint.   

FFS, how difficult is it not to sound like a three year-old, and type "want to"?

Yes, it is possible, if you can explain where the time comes from, if not from the RTC.

The veggies need not feel quite so smug - their 'sausages' have been found to contain traces of uni-quorn

I see words, but in a strange, meaning-deficient arrangement.
Did Google Translate have a brain-fart?

The phrase you're struggling with is "want to".
