How to make a sound reactive RGB LED strip with Arduino

Download the Arduino code from here-

Parts required:
1. Addressable LED strip
2. Arduino board
3. Sparkfun sound detector module
4. Jumper cables

Love it!!! works great. I made two 7 foot high poles to sit beside my DJ speakers and bump the ceiling to the music. thank you!

Is is also possible to do this exact effect for only a certain frequency range? I want to put like 10 of these next to eachother and have every single one do its own range of the frequency. Thanks in advance!

Shall I use a normal audio sensor bez what you suggested is that the audio sensor is too costly 😢

1:06 Are you sure the wiring is correct? The sound detector is not attached to a power source 😮

Hello Rupak, just wondering will a Arduino Nano work with this setup? Also, what are the jumper cables for? and for the Sparkfun sound detector which is better the one with headers or no headers - what's the benefit to getting the one with the headers.

I don't have the Sparkfun board How will I do this? can I modify the code so it works with 4 pins? I need the same effect as shown in this video. Get back to me.

How much power supply are you using? need your help .

[spyby]

my light is flickering but otherwise it works. How can i stop the flickering of the leds?

[AhaanM]

Where did you buy the sound detector from?

If the LED strip has 4 wire ( white, green, red, blue) How to use that on this circuit? please explain 1:14

[imanenarimane]

hello, please i want to ask you about the code ..

[meesh]

Hey, my light strip is not lighting up. Any tips? I also dmed you on instagram

[katedibble]

Hi Rupak! I am using your code on an Arduino installation at a museum. Unfortunately, I have little programming experience. Would you be willing to chat and give me a few pointers?

[abrahambruiz]

I must be doing something wrong when trying to upload the code into arduino. I keep on getting an error message that says: FastLED.h: No such file or directory. I'm definitely a beginner with this and would appreciate getting any help I can get. Do you you do any 1-1 tutorials via zoom or something? I can venmo you for your time helping me.

Bro can you make one and courier plz❤️

[anmolpanwar]

bro can we set a single colour if yes the how plzz

[MrMuhel]

Looks like an array bounds issue in the code.

for(int i = 0; i <= NUMLEDS; i++){

This is unusual - it would be normally "< NUMLEDS" for every loop.

which transformer can i use for the led strip? ok 12V
