Nice video 😀 I liked how, due to the nature of the sound, the random neopixels seemed to match the audio, even though they were just random 👍
Yeah, I made it all the way to the end. Keep sharing your great work.
Super video with very structured and helpful explanation of code and wiring - all thumbs up !!

Many thanks!
Awesome job, man! Greetings from Argentina 🎉 Canada is such a beatiful country! Recently visited Montreal and Ottawa with my family.

thanks a lot
These videos are great. I built a very simple MP3 player as a prototype for a museum, but just used buttons to trigger the DFplayer playback functions -- no MCU needed. Easy enough. Now I'm changing it up to use an Arduino Nano, and it will be used in a special project. Working with a local museum, I'm working on replacing the internal components of a WWII aircraft radio so while in flight, visitors can listen to radio recordings of D-Day from what appears to be a vintage radio. The hardest part of reusing the controls on the radio to to control audio playback.

Wow great project! Thanks for sharing
What's the "Busy" voltage and current? Is it possible to turn on a single led using it?
Thank you for this. I watched the entire video and enjoyed the detail within it.

Awesome, thank you!
Well done. Thank you!
I'm thinking about something similar. I'm building a jetpack and there's a servo triggering the smoke machine (canned air cans) and at the same time I want neopixels to light up . Any ideas?
Genial muy entretenido, claro que debe ser el modulo original.
Good video, Charles. You've given me more things to think about for future projects.
can you make that audio player connected in a Bluetooth via MIT APP INVENTOR?
Let's say I want to play an audio by sending a signal with the hc05 from an app, but it doesn't work and it doesn't work, would you make a tutorial about that?
Hi and thank you so much for such a helpful video! I have a 5 watt / 8 ohms speaker that i want to use for a project. Will it be okay if I connect the speaker to the DFPlayer Mini module? Or do i need an amplifier?

I am not really sure, I am not an expert in electronics, my concern will be that it could drive too much current for the module.
I agree with @daveshillito... Was the led actually tied to the sound, even though the code is random? It's not possible to actually synch it is it.. i mean unless you add a sound analyzer, mic, and some logic i guess?

In the code, it is just random, it appears to sync with the sound, but it is not. It would require another component to actually get the sound level.

Hi, Can you help me with my project with my DFplayer?
Hello! First of all I would like to thank you for this video and the good explanations. They are very useful and interesting. Secondly, I have tried to build this project exactly as in the video but I have a problem and I don't understand why. I have a 16GB SD card (hama) and I put a mp3 file on it, a song downloaded from youtube using mp3 converter online. After the mp3 is initialized the song doesn't start to play. The busy pin is always 1. I have checked the wires thousand times without any result. I have also displayed in the serial monitor the number of files on my SD card and the result was kinda weird because it was displaying "-1". I have tried also with another SD card and I had the same result. What can I do to solve this problem?

Think I can use this LED idea on my Sith Wayfinder project. Just need to find a way of adding a PIR sensor to the MP3 player and arduino nano so that it automatically plays when picking up movement
Very nice project.loved your work men..👌👍.
hi bro.Have a good time. i have one problem. for example in this code else if (inputvalue == '3') { mp3.playTrackNumber(5, 30); } else if (inputvalue == 't') { } what code need for stop mp3 file in secend else if ? thanks
