raspi zero wh question
February 25, 2024, 21:13
so like i want a raspi zero wh to make an led visualizer for a piano, but it requires a microsd card port and a usb port, i have no idea how to assemble these
the micro SD card can be found anywhere online for example: Amazon, and do you have a pc/laptop? especially with a SD card reader
i have a laptop, it has an ssd port but not a micro one
idk if microsd works on the ssd port
its not that
its the port on the raspi
not the card itself
that should come with the pi no?
i uh
i found one on amazon but idk
i dont know what the port looks like
should i sent the amazon link or
have you got the raspberry pi zero?
no-
not yet
im looking for one
i need to make sure ill find all the equipment before i start buying
well you don't need to find a micro SD card port and usb port that comes with the pi
is it already inside or do i need to assemlbe it
becuase i dont see any ports here
or im extremely dumb
becuase theres no microsd here
i got the stuff from a tutorial page and it linked here
oh thats a port
no you get the actual micro SD online
no no i meant prot
port
ik
i have the microsd ready
wlel the page
you don't have to worry about that
bye gtg now
also um
okay
maybe i can help
what is it
this is mostly abt the piano but idk
so my piano doenst have a usb port but an aux port
so will an aux male to usb male adapter work?
on raspi
uhh
u're plugging it into a piano
oh
hm
i understand i think
keyboard*
wait
but sure
do u want the vid ðŸ˜
oh ok makes more sense that way
ðŸ˜
ya sorry
i was wondering how u had an aux port on a whole ass piano
ðŸ˜
IM DYING
i was wondering "where the fuck did this dude find a piano with an aux port"
okay so
uhh
lemme think
on saturn
i dont actually know how that works
takes a bit to deliver but its good
so u want to plug it into the piano
and visualize the output?
lmao
the visualiser is led lights
do u want the vid?
yup
mayeb ull udnerstand better from there
also here is the github page
with the instructions
but idk im stupid for this
sorry answering two threads at the same time on a phone is hard
ðŸ˜
I'll look at it in a bit
alright no worries
take ur time
thanks for tryna help
mission failed
i asked the owner
an aux to midi port wont work
sad
which makes sense bcause aux is audio
damn
i mean
cant u buy an aux port
and use the gpio
the thing is
the raspi needs a usb midi
so it can detect which notes r being played
so it can know what light to turn on
an aux port is audio
so i dont think an adapter will work
i found another keyboard but its definitely not worth buy just for led
usb audio dongle?
or same problem
havent really tried any audio stuff
well the creator said this
soo idk
Midi is NOT audio, its digital signals. See https://en.wikipedia.org/wiki/MIDI
yes i know
so an aux to midi signals eh
sad
true
alr guys ty for the help
gotta skidadle
Before you read - I haven't solved your issue but just want to offer what I learned about the problems with aux in.
I was interested in this issue, but no knowledge of audio > midi conversion or anything like that, looked into it a little bit and just since you might be interested - one key issue with converting aux audi to a midi signal is
When you hit 4 keys at once:
With midi - You get 4 specific digital messages outputting the details of the keys that are pressed
With Aux / Audio - You get the combined sound of all 4 keys at once, which makes it very difficult for a 'converter' to extract and pinpoint the information of each key accurately.
So trying to light up an led at the exact position of the key press on the keyboard could work at a very rough level for single keys, but when it comes to chords or any combination of keys things probably wouldn't align nicely.
Again this is my first look into this stuff so I may have some incorrect assumptions.
yup that sounds right
