24x16 LED Audio Visualizer using MSGEQ7

hello friends,

i new arduino , learning scratch. did few projects , want concentrate on audio visualizer project.

i have seen 1 video on youtube , wanted know how achieve effect.

i have build 40led 10 band equalizer without micro-controller circuit has way components , huge. want build using arduino. specially scope effect.

i know msgeq7 has 7 freq band, not getting how scope effect on screen. confused how people build visualizer using msgeq7 more 7 band.

would appreciate help.

thank you,
best regards,
ns

hi

john boxall @ tronixstuff wrote this tutorial on how using these arduino relatively simple way of creating spectrum analyser.  scope effect on screen you'd need write code output kind of bargraph representation per frequency , display peaks of that.  part dependent on particular screen, , kind of effect looking create.

as far understand frequency bands hard coded on ic (for details : the datasheet), if you've seen more 7 bands i'm presuming stereo left , right 2 msgeq7 ics give 14?

cheers ! geoff
