Hello,

I've tryed to control a led on my arduino with voice based on the python exemples from MRL ( arduino ouput and talkback) , and nothing happen, i've just an error . But i just starting to learn python and i don't see the problem . Could someone help me ?

Or perhaps, all is wrong lol ! If it's the case , i'll retry from start ...

 

Thanks

 

This is the error returned by MRL :

1799832 [Thread-21] ERROR org.myrobotlab.logging.Logging  - ------

Try with this one : in red the part modified, and i removed the arduino.pinMode part (not necessary)

Heh... You have Gremlins !!!  

I use bug spray to get rid of them ;)

I copied your posted script and it works fine for me - albiet I my puter is not attached to an Arduino at the moment I can see the control messages go out.

The \r & \n  makes me believe you didn't copy it all the way, have extra lines at the top.. Perhaps an extra space or tab ?

Python is VERY picky about formatting, sometimes you loose or add a little extra in the process of copying code from the web to the Python window...

Thx,

Yes, this script work well laugh but on my desktop pc, not on my laptop ...

The gremlins are gone ( Note for myself: " not eat near my pc after midnight "cool) , but i've problem with my microphone, i'm looking for repair that yes
