Sorry I forgot to mention that you have to open the Serial Plotter not the Serial Monitor. You can test your code with a video that plays a sine wave (such as this one) You then shoud see the sine wave on your serial plotter.
1.68k resistors should work fine. I think the problem are not the resistors but the code. Are you able to send a screenshot of your serial monitor when you apply music to your arduino?
I'm glad you're trying to follow my instructables. However I'm sorry that I can't really help you with the code because a friend of mine wrote it. Is there any chance to change your led connection to the one i showed in the instructables? (desolder the cables and solder them in the correct way)Also check out my new video I made about the spectrum analyzer:
You can use any analog pin you like :) Just change it in the code
Thats true but ther are only few songs I now that habe such high differences. Furthermore I have already glued up my case and don't want to open it again.
Thank you :)
Thanks :) I already di upload a youtube video. The third picture is actually the video :) But due to a copyright claim it is without music. I am going to make a new video today.
