Arduino / Processing Audio Spectrum Analyzer
You need to use this library https://github.com/ACKspace/ht1632cConnecting it directly like in tutorial will work. Connect +12V line 5V in arduino and GND to GND.
Everything works ok for me, but i having a lot problems with sending the audio source from my computer to processing, how can i solve it?Cheers
I was excited to read the article, wow arduino and analyzes the audio.... but unfortunatelly it is not - the name is misleading. Arduino is used just to show LED matrix. What a pity...p.s. I am considering to make a project "Arduino + audio analyzer chip". But is becomes very expensive..... I should go back to old fashion several "resistors+inductions" audio solution :-)
Is there any chance you would know of pin out for the DE-DP14116 12volt version of your board. They redesigned it but cant supply any documentation so cant connect to it, yet
Great job Keanan. I got DE-DP14116 the re-designed 3216 3mm from Sure Electronics. The connector is different and it requires a 12V power supply. Whats the wire diagram from the 10pin connector to Arduino for DE-DP14116?Secondly I got Arduino compile errors. Suggestions?Arduino: 1.6.9 (Windows 10), Board: "Arduino/GenuinoUno"In file included from C:\Program Files(x86)\Arduino\Audio_Spectrum_from_Processing_3216_double_bar_ino\Audio_Spectrum_from_Processing_3216_double_bar_ino.ino:1:0:C:\Program Files(x86)\Arduino\libraries\ht1632c/ht1632c.h:168:34: error: 'prog_uint16_t' hasnot been declared void putbitmap(int x, int y,prog_uint16_t *bitmap, byte w, byte h, byte color); ^C:\Program Files(x86)\Arduino\libraries\ht1632c/ht1632c.h:192:5: error: 'prog_uint8_t' does notname a type prog_uint8_t *font; ^C:\Program Files(x86)\Arduino\libraries\ht1632c/ht1632c.h:193:5: error: 'prog_uint16_t' doesnot name a type prog_uint16_t *wfont; ^exit status 1Error compiling for board Arduino/Genuino Uno.Thanks in advance!
best way i can think of is to use virtual audio cable. It creates and combines a output source and input source. so then you use the included software to send your input (your Guitar) into the virtual audio cable output. if you are having troubles, pm (Private message) my Instructables account. :D Good Luck!
You don't use any audio chips ? Because i'm seeing in other projects people using.
Thank you for the tutorial! Would it be possible to do this using addressable WS2811 LED strips that a are mounted in a row of 36 by 10 LEDs. I need them to be strips since I am placing the LEDs on fabric. Any recommendations would be greatly appreciated. Thank! The picture shows sort of what I am trying to achieve.
Do you have a video showing the visual effect acquired with this project?
how did you fix this??? i am having the same problem
im just wondering how the FFT program connects to the stereo mixer, the "java (tm) platform se binary pops up but is not reading any audio levels, iv tried playing stuff from youtube and plugin my iphone still not reading anything
