Trying To Get Led To Flicker While Sound Is Playing

Skip to comments   Jump to end

I am building a semi static BB8 (from Star Wars) out of foam. I have the EZb playing different sound files when a button is pressed (I have it set up for mobile, I press a button and it randomly plays one of several sound files). What I am trying to do is get it so that when it plays a sound file an LED flickers on and off while sound is playing and then stops when sound stops. I have managed to do the Sound servo script and it works, but the LED also flickers when ever there is a external sound. Can anyone help me out with this please.

Thank you. Jamie https://www.facebook.com/FoamtasticCreations/

Just noticed on the soundboard it has an edit option. Wondering if I could make a script for each sound file?. I will have to try it when my battery charges back up.

You can - or you can attach an led to the speaker output.

Sweet, never thought of that. I have to move the speaker anyway, so adding the LED to it would work. Awesome thanks.

Credit to Patrick. A search might find it. He has a YouTube video demoing it

DJ, would'nt sound servo also work for control of an LED synced with sound?

Yeah - that's a good point. You could connect an led to a digital pin and use sound servo. Good idea Justin

I mentioned in my first post that I tried the sound servo thing, but found that any sound even external would set off the LED. I needed it so that only the when the sound file is being played would the LED flicker. But thanks. I am going to try putting some script in each of the sound files, that way I can control how bright the LED flickers depending on the sound file being played. Thanks to everyone for helping me out. Jamie.

Remember, there are 3 sound servo controls:

Sound servo PC MIC - that would pic up any sound from the MIC on your PC.

Sound servo PC Speaker - that would pic up only sounds played through the speaker.

Sound servo EZB Playback - that would pick up only sounds played through the EZB Speaker.

I just wanted to mention that to make sure you know about the 3 different options.
