How To Control Servo Moving When Play Music Or Audio?

Question

Hi,

Anyone can help to control the servo moving during play music? EZB4 have a talk servo function for text speech. But how about the music or audio?

I have tried the Sound board(PC) and Sound Servo(PC Speaker) to play the Music file, then the sound servo screen have a wave form, but the servo motor is not active(It already set min. & max number).

Pls. note the attached picture for ref.

Can anyone help to answer this question?

Thanks a lot!

"Soundboard EZB" will do what you want. https://synthiam.com/Tutorials/Help.aspx?id=199 But if you want to use the "Soundboard PC" and "Sound Servo (PC speaker)", you can use a simple script. Add an "Ez-Script" control to your project, and, as an example, add the following example script...
#Assuming servo is connected to port D0 loop if($SoundValue >30) Servo(D0,180) Sleep(500) elseif($SoundValue <29) Servo(D0,1) Sleep(500) endif sleep(100) goto(loop)

When the sound level goes above 30, the servo will move to position 180. When the sound level is below 29, the servo will move to position 1. Play with the "Update Speed" and "Scalar" settings, and the servo positions and length of sleep()'s in the script to suit your needs.

@rickymahk2013 Post your project with the soundboard EZB in it so one (or more) of us can test. I suspect we might have another locale/internationalization issue, but I am not sure. Would like to see what the error message is saying in English if the problem is duplicated on US systems. Can you tell us what that error message is saying? Might be good to make a zip file and also include the MP3 you are using, so we can see if it is an issue with the music file itself. Alan
