    Spectrum analyser Equalizer project how to go about it?

    Okay so I found this! https://github.com/espressif/arduino-esp32/releases/download/2.0.11/esp32-2.0.11.zip how do I add it to the arduino IDE? thanks

    I have downloaded the http://downloads.arduino.cc/tools/dfu-util-0.11-arduino5-windows_386.tar.gz it has an exe file how do I get it to work with arduino IDE?

    perhaps these numbers are better 41.5 Hz 53.8 Hz 69.8 Hz 90.5 Hz 117 Hz 151 Hz 196 Hz 253 Hz 328 Hz 424 Hz 549 Hz 710 Hz 917 Hz 1186 Hz 1532 Hz 1980 Hz 2559 Hz 3306 Hz 4265 Hz 5489 Hz 7050 Hz 9032 Hz 11631 Hz 14955 Hz

    ok how would you split the columbs from 32 on the left an 16000 on the left evenly spaced in between

    not sure il work it out again does anybody have a .zip file for the esp32 because my internet does not allow me to download and add

    Spectrum analyser Equalizer project how to go about it?

    I found the code it uses WS2812 LED panel can it be adapted to work with my 24 column 20 row (where the anodes are connected down the columns and the cathodes across the rows) the frequency goes from 32hz to 16khz logarithmically going from 32, 37.72, 44.5, 52.49, 61.96, 73.15, 86.35, 101.92...

    essentially I want this but I want 24 columns and 20 rows, but he didn't upload the code!!

    Spectrum analyser Equalizer project how to go about it?

    so say the cycling is 24 columns each for 25hz then 600 pulses each light will be on for 1/600 = 1.67milliseconds and I want to display the amplitude for this column each time the light is on gives me 1.67 second to process and display the leds which is pretty tight and the lights won't be on...

    ok so I'm confused how do you map the frequencies to the columns and have the amplitude update every time the column moves to the next in line I'm thinking of wiring up the leds in the configuration of ws2812b wiring diagram is it transposable to my led matrix

    Spectrum analyser Equalizer project how to go about it?

    the problem I have is that when each column is is on I need the rows to correspond to the column that is on for example if column 17 is on and the decibels (amplitude) is say 12 decibel (3 decibels per led upward) 4 leds on then when it clicks over to 18 that might have only 9 decibels lighting...

    Spectrum analyser Equalizer project how to go about it?

    ok so the thing i was looking at says that each of the columns need to be flashed at 60 hz and 1 columb is on one at a time ther're 24 columns so that equal 1440 pulses in a second but if you're say that the update rate of each led in the columns need to only be 25hz then that equal 600 pulses...

    building an LED spectrum visualizer using a LED matrix. You want to use 74HC595 shift registers to manage the rows and columns, and the data should correspond to frequency bands extracted from an audio signal. Let's break it down step-by-step: LED Matrix Setup: Your matrix consists of 24...

    Spectrum analyser Equalizer project how to go about it?

    I am going to have a esp32 nano. I want to build a Led matrix of 480 leds 24bands/columns/channels and 20 in each row. I will be using 74HC595's, 3 for the columns (thats 24) and 3 for the rows (24 but i'm using 20) there are 20 rows the columns are updated each 60hz so across the set of 24...

    Spectrum analyser Equalizer project how to go about it?

    I think this method is more pactical for me I need it explaining though so the actual name for the 7459 is 74HC595 and it's a shift reigister I want to know how to utilise 6 of them, 3 for the x axis 24 bands and 3 for the y axis 20 for a total of 480 LED's so there will be 6 74HC595 chips. I...
