My reply was that it took most people several hours to not understand it, and that they should persist.
I think that came out wrong - I'm not doing noobs down for not understanding a particular concept, just saying that they should stick at it, before posting "I don't get it".

What bandwidth do you want?

You can't increase the sensitivity of the device - it is fixed by the geometry of the MEMS device and the internal circuit.

I'm giving it a lot of thought!

I remembered one user who came back to the forum only about ten minutes after being pointed at "blink without delay" for the first time, complaining s/he didn't understand it.

I would suggest you work through some of the example sketches in the IDE, in particular, the 'blink without delay' sketch.

I would go so far as to suggest it should be a requirement for joining the forum.

Amen.

OK, I concede, it is a bit of a paper-trail

http://arduino.cc/en/Reference/Libraries

takes you here:

http://code.google.com/p/arduino-tone/

and then here:

http://code.google.com/p/rogue-code/wiki/ToneLibraryDocumentation

Where it says that with a clock speed of 8MHz, the minimum frequency is 31Hz with an eight bit timer.

This topic has been moved to Bar Sport.

Couldn't really think of a better category, but "Project Guidance" doesn't really fit either.

No, I'm saying what the code does, does not agree with what the comment says.
The clue is in the end condition of the loop, and what gets written to the servo or ESC object.

Example:
Code:
for(pos = 90; pos < 130; pos += 20)  // goes from 90 degrees "neutral" to 130 degrees "foward speed"
You might think from the comment that the values 90, 110 and 130 are written to the servo object, but in fact, the values written are 90 and 110, simply because 110 + 20 is NOT less than 130.
As I said, this may or not be important to the correct functioning of the device, but it could confuse someone at a first reading.

Strictly speaking, you should only use true or false to initialise a boolean

Perhaps the slow response is partly due to the 1/5th of a second delay.

I give up.
Really.

Please read reply #150 (!!) again, and try to translate it to English, please.

Your signal to noise ratio is dropping badly.
17609  Using Arduino / Programming Questions / Re: Tone frequency limits. on: January 24, 2012, 03:39:24 pm
I think it is in the documentation.

Yup, it is.

println, by preference, but yes.
