14 Band Spectrum Analyzer Part.1 | Tutorial using Arduino & WS2812

This spectrum analyzers is not two 7 band analyzer operating in stereo. This is a true 14 band analyzers, with accurate frequencies beginning from 40Hz to 16KHz.
This project uses the Arduino Mega 2560 because it has a large enough memory and better performance.
Si5351mcu boards are used for programming masterclock IC frequencies (MSGEQ7).
The Si5351mcu library is needed for this programming.
Special thanks to Pavel Milanes for his outstanding work.

The MSGEQ7 IC is very rare because of limited stock and many sellers sell it but cannot work. if you are having trouble getting an msgeq7 ic you can contact our seller. We guarantee the MSGEQ7 IC can work well.

Thanks all for watching.

Wow very impressiv, thank You for sharing this awsome Project

[abensu]

Excellent!!! Well done!!! Real spectrum analyzer. Thanks

[rendrafams]

Firts view 😁 akhirnya ada juga tutor detailnya.. thx platinum

[tiborstaron]

Great Job Man !!! Very beatiful,
I'll also make it

[eliaschugar]

Excelente felicitaciones por tu trabajo 👌

:D :D :D i watched this and didn`t believe it...cause i didn`t see the datacable :D :D :D .... i thought : HOW CAN THIS BE ...THEY ARE ALL IN A ROW :D :D :D then i downloaded the sheet and saw it :D ...thanks pal ....looks awesome

HI I am confused how you can achieve 14 bands when the MSGEQ7 chips are fixed at 7 discrete bands? Looking at your schematic you just have everything wired in parallel with the same signal fed to both chips so wouldn't both MSGEQ7 chips just output the same data or am I missing something here?

I'm building a version of this. 14 channels, 144 LEDs tall on a 2ft x 3ft board. I'm thinking of a second arduino to run VU meters in the middle.

Gan, potensiometer nya di schematic diagram kok tidak ada ya? Pliss help...pengen nyobain project ini.

[Dancopymus]

What are the references in Hz (Hertz) values to mark the 7 frequencies of each channel, at the bottom of each LED strip, for example? Thank you

Hi master, thank you !you are a genious !but however, i can't find a single person on youtube showing how the make a single floating point spectrum analyzer 😂

nice build ...question where to buy 7 band digital spectrum analyzer curcuit board ?

[elgustinlongoagostino]

Wow it's amazing, but where can i found theese components? i have searched in Italy, e-bay etc. but i have not found some components. Can you give me any suggestion? Thank's

[satyamshivam]

Very nice i like this will you give me circuit diagram 2.0 dms 308?

[donaldhenke]

how to build if you cant find the dam boards
????

[ranulfo]

AMIGO, BOA NOITE. POSSO USAR UM ARDUINO NANO OU UNO NO LUGAR DO MEGA ? OBRIGADO E PARABÉNS PELO VÍDEO.


TEMAN, MALAM BAIK. BISAKAH SAYA BISA MENGGUNAKAN NANO ARDUINO ATAU SATU DALAM MEGA? TERIMA KASIH DAN SELAMAT TERHADAP VIDEO.

[dennisbaring]

Where can we find this 7 band digital spectrum analyzer PCB board???

[rsayeed]

hello dear, thanks for the code. but i faced a problem. in my 14 column led last 4column peak is always hold not falling. can you please help me

[abablack]

Can I use a normal arduino Nano or uno or has the arduino mega special features?
