UnoR3   @16MHz   IDE 1.5.2
double   usec
Not really a fair comparison - 32 bit float vs. 64 bit double.

3  Using Arduino / General Electronics / Re: Unsure what supply voltage to use to calculate resistance on: June 18, 2013, 03:35:25 pm
"A shift register", "a driver ic" and "an LED"
Feel free to provide any relevant details.
4  Using Arduino / Programming Questions / Re: would like some feedback if possible on code. on: June 18, 2013, 03:31:30 pm
Code:
delay(500);
Latency, you say?

(Do you see why we ask you to use code tags?)

I'm not sure what the resistors might be for.
Not a voltage divider, I hope.
Use a regulator or DC-DC converter.

tell me what the ultra-amp circuit is for?
Amplifying the very weak echo signal.

How can it be so cheap
Why don't you ask them how repeatable that six to thirty feet is?

I could get maybe devices that have a predefined distance at which they can transmit.
Not at reasonable cost or in very constrained conditions, no.

Here's my attempt at adding code tags. Hope it works.
Close. Very close.

Doesn't 180 degrees depend on the limit of the motor
It does, which is why I wrote "degrees" in quotes.
It still doesn't go to 180 anything - look at the first "for" loop limits.

@AWOL, perhaps you would be kind enough to RTFM and tell me where it explains ISR()?
It doesn't, so that's how you know when and when not to use it.

That's Processing

Any clue why it's pos>=1 instead of pos>=0?
No, I've never understood that example - it doesn't go to 180 "degrees" either, despite the comment.

Add some "Serial.println(val);"...
...and some code tags
