76  Using Arduino / Motors, Mechanics, and Power / problem with servo on: February 08, 2013, 01:51:40 pm
When I attached the servo as said in this tutorial:
http://playground.arduino.cc/Learning/SingleServoExample
,I encountered a problem. As soon as I connect the servo, either it keeps on rotating continuously or the Arduino gets disconnected from the computer.

Any help is welcome
77  International / India / Arduino Promini program burning problem on: February 08, 2013, 04:23:00 am
I recently got an Arduino Pro Mini 3.3V/8MHz & also I was having a FTDI Break out board
(This one):

Now The Rx-TX lines are of 5volts here unlike the Sparkfun's FTDI board which is having a jumper two logically lower the communication pins.
My Board on the other hand have only a 3.3v VCC line along with a separate 5v VCC, but no jumper to logically lower the communication pins.

I did a mistake:
I connected the 3.3v of the FTDI board to the Arduino Pro mini's VCC.
Rx(5volt logic) of FTDI board - Tx of Arduino Pro mini.
Tx(5volt logic) of FTDI board - Rx of Arduino Pro mini.
Gnd - GND.

And now all my pins of arduino Pro mini shows 3.3v high logic when I disconnected the FTDI board & connected a 3.3v poer supply to the Arduino.

Is it fried? I ordered the Sparkfun's 3.3v FTDI board recently.

Woohoo!!! It compiled. After I deleted the extra folder, it worked.
Thanks

this is what's in the folder (after I rename it as "uSpeech"- as Arduino was not taking the file name as it was downloaded).

this is the header file

 uspeech is a library that allows sounds to be classified into certain phonemes
 on the Arduino. This creates a simple beginning for a full scale voice recognition
 program.

It says so that the uspeech.h file's absent, but it's there in the folder:

I'm having Arduino 1.0
& I guess boards doesn't matter for compilation.
In the topmost line- signal voice(A0);

84  Development / Other Software Development / Re: uSpeech library on: February 07, 2013, 02:12:49 pm
Yeah I mean speech training.INO
I did put it in the "library" folder.
No, I did not move it from "_SpeechAdvancedTraining" folder from uSpeech/installation/examples to uSpeech/examples
i did not shut down the computer but re-started the Arduino IDE.
Yes, I did selected "SpeechAdvancedTraining" from File->Examples->uSpeech->_SpeechAdvancedTraining.

I'm staying in India & I got is in handy:

Obviously I'm talking about the speed that get's printed in serial monitor.
86  Development / Other Software Development / uSpeech library on: February 07, 2013, 12:43:43 pm
yesterday I was searching for some speech recognition stuff & i found out a so called nice speech recognition library for arduino named uSpeech.
here is the link:
http://arjo129.github.com/uSpeech/
I followed the installation & training & calibration guide as in here:
http://arjo129.github.com/uSpeech/.
 I'm having ArduinoIDE version 1.0.0
& when I wanted to run the training sketch I got an error msg saying : 'signal' type not found .
Need help with it.

umm, Is there any way of putting the velocity at 0 mph when not detecting anything? Cause here(when I experimented with it) when I did not move my hand, it still showed 2 mph & that's not acceptable in some cases.
