Have you tried to use analog pins to define a better signal variation or does MINIM not do analog? Also,rather than just on and off – have you tried to connect multiple lights to include fade-in’s/out’s to denote beats other than a solid beat and silence?

please can you share the code,

Very nice! I’m working on a similar project. Any chance you could share your code?

Thanks alot!

I’m completely new to this since I’m not an engineering student. I’ll try out what you told me. Thanks again.

@Sally I used MINIM to do the beat detection - I then sent it to the arduino using processing's serial connection. I just sent a 1 or a 0 determining if the light should be on or not. If you wanted to actually play music via minim on the arduino would be a different story. If you wanted to interface with speakers, you could put the output from the analog output pins on the arduino through an amplifier (LM386?) and then to the speakers. I'm not sure what quality of sound you might get out of it either. If you dont have analog out, then a digital-to-analog convert -> LM386 should work as well. Thats more complicated though. Software wise, I would look at the AudioBuffer class in Minim to extract the sound data. Good luck, Andrew

Hey Andrew,

It’s really cool that you were able to rig it up so quickly!
I’m doing a similar project but I used an Arduino Shield to play music instead. I am stuck in one part that I’m guessing you are the only one who can answer. How did you manage to send the output of beat signals to the arduino through MINIM? Did you have to code something?

Please help!

This looks awesome! I can’t wait to see the finished project.

I second Joe’s request.
I’d love to see how you set this up, if that’s okay with you.
Thanks!

very cool! Any chance that you could upload the arduino and proccessing code?
Thanks,
Joe
