i want to input the current and temperature values in raspberry pi3. i already have a ADC ADS1115 and able to figure out the electrical connections , but the programming part is bit difficult. can you guys help me ?

I have a Raspberry pi 4 and my goal is to connect it to some LEDs that will react to music that is playing through bluetooth (or AirPlay, ...). I've installed rpi audio receiver and so now I can stream music to it.
Now I need to write (or use some) code, that could parse what is being played to the audio output (via built-in 3.5mm jack), so the main question now is:
Is it better (or possible) to intercept the audio somewhere and analyse it with my own code, or does this require some deep modifications to the streaming program? Or do you know of a better solution that could point me to the right direction?
I saw a lot of people using an external mic, but the whole process is too different from mine.
Type of LED strip is not important right now, if I'm able to write my own code for it.
Thanks for any help!
I am looking for RPi alternatives with audio inputs. I prefer 192kHz 24 bit line in yet any audio input also fine.
There was a board like pi which have input jack at just below of output jack but I didn't find it. Maybe you know it.
Please let me know your alternatives.
I am building a self driving car model using python(tensorflow). The architecture design of my project looks like the following. The CNN code will be in the raspberry pi, which is connected to a radio controller using wires from it's GPIO pins to send motion signals. The pi then controls the car. To "see" what's around it, the car uses a webcam that is mounted at the front center(this is the puzzle), which I wanted to stream the video to the pi; then the pi will use it's trained model(brain) to decide whether or not to move forward, make a left turn, a right turn and so on. The pi and rc radio controller are not mounted on the car, and I want them to remain that way for a reason. The car has the webcam and that is it. I am considering replacing the webcam with an android phone due to lack of alternatives, but I would hate to do that. If you would like more explanation on the structure of my project, please comment down there.
My question is how can I stream the video to my pi in real time?
I'm trying a project to simulate a brass trombone. The materials I'm using are a Seeed Studio Ultrasonic distance sensor, Raspberry Pi, and an Arduino. I'm going to connect the sensor to the Arduino, and the Arduino to the Raspberry Pi.
I'm looking to have the Raspberry Pi play one steady sound out of the audio jack. As the distance between my hand and the sensor get larger, the pitch of the emitted sound should get lower.
I'm not too familiar with using audio in programming, or too much of programming for that fact. Could someone help me write up some code (preferably in java or C#)? I'm very anxious to do this as I play trombone in school. Any help or suggestions are appreciated.
As not to recreate the brass trombone from scratch, use a Midi Synth on the Pi, such as TiMidity (apt-get install timidity) or alike. With this you can bridge between the Arduino's output and the note(s) sent to TiMidity to play out the Pi's speaker.
I am sending serial data to my raspberry pi from my arduino then converting the serial data to MIDI using this program: link. Is there any program out there that will take the midi input from the converter program and send it out the pi's audio jack in real time?
I've been using fluidsynth as a softsynth. I haven't run any on the pi, though. There's also a lot of others like amsynth, hexter, xsynth-dssi etc and some of them might be more suitable than others.
You might try running apt-cache search with some suitable keywords and look for programs available on the pi.
TiMidity++ is a software MIDI sequencer and synthesizer that supports multiple audio and patch formats.
