Change the update speed to see if it speeds it up.

Check you are using the correct Sound servo control, you want to use Sound servo (EZB). Adjust the settings for update speed and for scalar. Reset the servo speed and check nothing else has changed/is changing the servo speed. Check that your PC isn't being bogged down by anything, if it's a slow PC that may be what is causing the issues.

Well, I did checked all of this... Everything is ok. But the issue continues. Do You think it could be the kind of servo (I am using micro servos - those clear blue ones )... Or mabe power, since I am feeding the ezb with 7.5 volts and using the board power feed to servos...? And, I've been playing with Scalar and speed, with no success.. Can you guess some good relation to that ? Thanks!

Hello tevans.

If you are using the sound on the ezb, check to see that the microphone that is to pick up the sound is located near or on the board or close to the speaker. I could be wrong but i believe that the sound servo module listens to levels on a microphone.

I have those servos too. I can confirm they DO NOT like more than 6v.... They chatter like crazy and often move to the wrong position if you use 7.4v instead of 5v or 6v... I use these now... 7.4V Mini servo

I can confirm those small blue servos don't like 7.4v at all, mine gave up working quickly after applying 7.4v to it.

are you shure that the speaker should be near the board ? I mean, when using sayEZB it does not send the sound value to the soundservo ? instead the sound must be "listen"by the MIc ?!

The Sound servo (EZB) control doesn't use the mic.
