Hi devs! i'm new here in this environment. i'm not a programmer, i'm just a mere DIY-ers and making a small project and i found some a nice ideas/project somewhere and i take a look and copy a project and edit etc. and, i just want to know how to fix this says " Adafruit_SSD1306.h: No such file or directory"
C:\Users\dell\Downloads\firmware_2.1\firmware_2.1.ino:9:10: fatal error: Adafruit_SSD1306.h: No such file or directory
9 | #include <Adafruit_SSD1306.h>
| ^~~~~~~~~~~~~~~~~~~~
compilation terminated.
exit status 1

Compilation error: Adafruit_SSD1306.h: No such file or directory.
i just want to merge some ideas/code from arduino and raspberry pi to make a streaming player.

thanks for understanding even im not good with english...

You should never post in the Uncategorised section.
It says so in the description of the section. Therefore I have moved your post here.

You might want to look at this How to get the best out of this forum before you proceed any further.
We only know what you tell us, and without knowing what you have, we don't stand a chance.

Also posting images of code is absolutely useless please don't do it.

Hi Grumpy_Mike! I'm so sorry for making such a mess with this forum, unfortunately, i am having a hard time to find and to know which thread should i post this and the other rules and instruction for posting.

Thanks,

Like I said "Read the description of the section you plan to post in" that is not too hard is it?

If it says "do not post here" then don't. Basically if you don't know then Software or project Guidance is a good place for most questions.

If you post your code, as described in the link I posted then we can see it and therefore try it. You should mention what sort of Arduino you are using as this makes a big difference to how things work.

Hi @kuyadrei_0502.

When you see a "No such file or directory" error like this, it almost always means you need to install the library that contains the missing file.

You can usually use the Arduino IDE Library Manager to install the library. I'll provide instructions you can follow to do that:

  1. Select Sketch > Include Library > Manage Libraries... from the Arduino IDE menus to open the "Library Manager" view in the left side panel.
  2. Type Adafruit SSD1306 in the "Filter your search..." field.
  3. Scroll down through the list of libraries until you see the "Adafruit_SSD1306" entry.
  4. You will see an "INSTALL" button at the bottom of the entry. Click the button.
    An "Install library dependencies" dialog will open.
  5. Click the "INSTALL ALL" button in the "Install library dependencies" dialog.
    The dialog will close.
  6. Wait for the installation process to finish, as indicated by a notification at the bottom right corner of the Arduino IDE window:

    ⓘ Successfully installed library ...

After doing that, try compiling your sketch again. Hopefully it will work as expected this time.

Hi there! Thanks currently i am installing some of libraries. Appreciate your help ans sorry for being idiot here coz I'm trying to learn to this new environment. And i am more aware and careful to do action such as posting without fully reading some rules and regulation here.

Thanks,

Thank you grumpy_Mike. Currently working and installing some libraries to work with my project appreciate your help. Next time I'll more careful to post anything that coz messing with forum.

'some libraries'???? Just one,

Hi sonofcy! i mean some just written here; #include <Arduino.h>
#include <ESP8266WiFi.h>
#include <ESP8266WiFiMulti.h>

Ok, so it's working now?

Yeahh, unfortunately i couldn't install thr correct/right library for rotary encoder. I show something like this.
C:\Users\dell\Downloads\firmware_2.1\firmware_2.1.ino:531:3: error: 'encoder' was not declared in this scope
531 | encoder->tick();

exit status 1

Compilation error: 'RotaryEncoder' does not name a type; did you mean 'RotaryEncoder_h'?

And here's my full code down below i hope is it allowed here.

The first thing you need to do is read the tutorial on how to use the forum. Code must be posted in code tags, must be Auto Formatted.
A quick look at your sketch shows two rotary encoder libraries. get rid of the
#include <KY040rotary.h> all you need is #include <RotaryEncoder.h>
Also what is all that stuff beginning with
PiCorePlayer volume control onkyo [HTTP]
Not needed

Hi sonofcy! apology for my late response . i already took out all those line with picorePlayer control.
i also delete the 'include 'KY040rotary.h' and i run a verify/compile and the result still the same and no idea which right library should i call for this . thanks

here are the message saying...
C:\Users\dell\Downloads\firmware_2.1\firmware_2.1.ino:529:3: error: 'encoder' was not declared in this scope
529 | encoder->tick();

exit status 1

Compilation error: 'RotaryEncoder' does not name a type; did you mean 'RotaryEncoder_h'?
