You are very welcome. Hopefully my 3hr diagrams was a masterpiece in your eyes :)

Got a question how do u line up the lights to the note if the lights are all of the place for 88 keys or does it have to be 144 led per m

@@eduardogonzajose50 I am using 144 led per meter in my yamaha dgx 670 and have placed it where the keys starts (simply using double tape of the rgb strip). As mentioned in the video, after installing the drivers, software itself calibrate the lights). You can also check in the link that he has provided in the description.

​@@kmusical00got another question thanks ,can I see how u setup your code or how many led you control because my flicks out

@@eduardogonzajose50 According to me, your lights are flickering because of low power supply. I personally have attached a mobile charging adapter(5v 3A) to the strip and changed the value of maximum current to 3A in Arduino controller software. Info. regarding it is published in the github link provided in the description. By the way, if you want photos of the setup you can mention your insta id if you are comfortable to do so.

Heyyy!!!! Is your LED still working today? I'm going to create mine this week

The Arduino man...Use an Arduino Leonardo instead

After reading that comment, I believe I am forced to take care :D. Truly would be but sadly arduino is only a micro controller (no OS support) t.t

yeah, I tried that

The LEDs power on through the connected micro USB, so there is no need for additional power For the demo I went to the software settings>LED Mode>Splash. That's the reason why there are additional lights surrounding the keys being played. By changing the LED mode, you can adjust it so it only lights up the key you play. Pi and Arduino (for this project's extent) does not matter. It's just a software that made the LED pattern like that.

@@klearliu Thank you very much! I appreciate your respond!

LOL actually there is. One thing that comes to mind is to use: Piezoelectric sensors or contact microphones Attach the sensors to the analog input pins on the Arduino board. Each sensor or contact will represent a piano key and generate an analog voltage. Then we can light the matching LEDs.

how are you recording the midi??? to make the falling notes

@@GabrielPiano1 Are you asking how I record something with falling notes onto the piano?

have you solved? same issue

​@@faxegameplay9918Yessir, jt doesnt work with an uno, you need an Leonardo Like He did in the vid

@@derfabian3377 thank you. Real leonardo or even a replica?

@@faxegameplay9918 i went with the original but a Replica should work Just fine

It could be that your fade settings are at zero. What version does your pianoLUX environment say? for example v4.3.6

First try adjusting the Fade slider to halfway and see if it works. Also sometimes the program could crash so just close the connection and reupload the arduino code. It may help.

@@MiyuCols well, first I tried PianoLux v4.1.3 (as the tutorial), and I thought that the error was by the .exe ( an "old" version) so I upgraded it to the latest version and modify the the Arduino Code...but I had the same error. I decided to read for more in the official website and I see that the error wasn't in the software, 'cuz it could be in the Arduino or the lights, but I think that it's by the lights (I use 3.2FT of light for a 61-keys piano, not for 88)

@@EmanuelRosado_official ​ @aemanuelrosado6763 It does seem like it might be the Arduino uno if you are having compiling errors. I recently tried using an arduino uno (although it is a clone arduino rather than official). It seems like the processor for the microcontroller might not be enough to handle FastLED. I use the arduino uno r4 wifi and it works fine with only a few extra steps including having to port FastLED from github. Try running the code I provided below in a new Arduino sketch and see if it works or not over a long runtime (youtube is being weird though I'm not sure if it will let me paste it):

Once the code is uploaded onto the Arduino board using a computer, it can operate independently without needing to be connected. To replace the PC of the project, we will need an extension for the Arduino to recognize USB input. Sadly, the Arduino Due cannot independently handle computations for the lights and piano inputs. Directly interfacing a MIDI keyboard with an Arduino through USB can be complex because most MIDI keyboards use USB for communication and require a host device (meaning a computer) to interpret the MIDI signals. Arduinos, in terms of piano, need help to handle that. Some devices were researched prior to this build to make it without a computer: - MIDI Shield - USB Host Shield The program heavily relies on the computer to interpret the MIDI signals, leading to the discontinuation of the plan. Hopefully, mentioning something about using MIDI and USB Host shields in this reply will inspire a solution.

Oke thanks for the reaction. Btw didnt you have issue's with using the app and led's that hang if you dont use splash mode. If so I know a sollution for the due

Splash mode is my favourite do tell :)

@klearliu I understand but dont you have a problem with the other modes. Were the led's hang?
