i have some problems with the way how the vu meter acts like. i never thought it would be that hard to make it look nice
i even dont know if its a hardware or software problem... its never doing that what i want it like. its acting tooo fast and more like a strobo or its to slow and has nothing to do with the music.
my hw setup is, an audio source which is going to an lm386 (gain 20) and then to the analog in from the arduino. it has a offset of 2.5V so the voltage the arduino is reading is between 0V and 5V. i also connected the hl1606 led strip (cutted down to 38 leds). everything is powered by a labor power supply.
btw.. tried a few rc filters (cutted off, everything above 15khz or let it react just with the bass)
yaa... i tried everything i know... first i modded the bargraph sketch but its too fast. then tried this average code but its still not doing what it should. some say it has to be log. other say linear. i have really nooo idea how to make it look nice..
would be very thankfull if someone knows how to do it.
