Вставка
- Опубліковано 23 лип 2024
- In this tutorial, learn how to create captivating LED visualizations that synchronize with your piano playing. Watch as we guide you through the step-by-step process of integrating LEDs with your piano using an Arduino Due microcontroller. Links to materials down below.
Discover how to capture the piano's input, whether through MIDI or audio, and process it to control the LED behavior. We'll explore different techniques to make the LEDs react to the intensity, pitch, or other parameters of the notes played on the piano.
No prior electronics or programming experience is required. We'll explain the concepts in a beginner-friendly manner, making it easy for anyone to follow along and create their own mesmerizing piano-LED light show.

Materials used in this tutorial:
- WS2812B LED Strips 144 LEDS 2m
- Arduino Uno, Leonardo, or Due microcontroller
- MIDI to USB cable (or audio-to-MIDI converter)
- Dupont/Jumper wires
- USB Extender (optional)
QUICK disclaimer, when you buy an LED strip that is 144, make sure to get a Leonardo or Due as your microcontroller to have the sufficient processing power. Using Uno for 144 will cause a noticeable delay.
I recommend these instead:
- WS2812B LED Strips 144 LEDS 2m
- Arduino Leonardo
- MIDI to USB cable (or audio-to-MIDI converter)
- Dupont/Jumper wires

the best tutorial !!
Beautifully explained. Thank you and God bless you
You are very welcome. Hopefully my 3hr diagrams was a masterpiece in your eyes :)
I went for the DUE and I'm REALLY upset, sometimes the key even light up and sometimes the light freezes and I need to hit again to lights fade out, what am I doing wrong?
how are you recording the midi??? to make the falling notes
very nice thx but i got a question. I did everythin exactly like you and when i was finished I was trying to play the keyboard and the lights didnt light up. i have to press one key multiple times to light it up and when they light up, they stay and wont go away, idk why pls help
how much it totally costs?
COME ON GET 50K LIKES!!
If you play a midi file in the laptop do the LEDs light too?
Your way of explaining is great! I have installed it and its working! Could you please answer that since the leds are powered through usb port can we supply additional power supply to the board by also connecting a micro usb to the other port or powering it through the DC 5V port because it seems to flicker when used in high brightness. THANKYOU!
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
Hi, thank you for your tutorial, it helps a lot, I just have a question about how the led turns on. On your example multiple leds turns on and not only the led below the key. I thought it was because of smaller led strips but I have seen other videos using also 144 and only turning on the leds under key playing. The difference I have seen is that other videos use Raspberry, could be that the reason?
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!
is there a way to do this on an acoustic piano? i know it sounds stupid but like surely someone out there has done some touch sensitive thingy idk
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.
Hi,
I like you and your video ... Very kind !
Would be nice without PC BTW :)
Take care !
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
Where are your covers? :(
Great video tho
Hey is it possible to link my arduino due to my keyboard after I put the code on it. So that I dont have to use my computer all the time and use a 5V power supply
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?
@@djemtheman0588 how are you recording the midi??? to make the falling notes
I need help. I got mixed up because when I tried to upload on the Arduino IDE it says, "Failed uploading: no upload port provided." I tried looking up the error message and it just says that either my Arduino isn't plugged in or I haven't selected it on the top left corner of the Arduino IDE. I have done both of those things and I now have no idea what to do.
Edit: Nevermind I got it :)

@@GabrielPiano1 Are you asking how I record something with falling notes onto the piano?
You are god bro! ❤
Help! I have a problem :(
I made all of the steps correctly, but when I press a key of my piano, the lights continue ON...
I use
-Arduino Uno
-Keyboard Casio CTK-3500
-LED ws2812b+144 5050 RGB (3.2FT)
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):

for (int k = 0; k < whiteFill; k++) {
leds[k] = CRGB(10, 10, 10); // this will be a dim white light

piano keys -> 72 keys/m *2 -> 144 so 2 leds/key
