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!
Well done. Thank you!
Awesome job, man! Greetings from Argentina 🎉 Canada is such a beatiful country! Recently visited Montreal and Ottawa with my family.
thanks a lot
Good video, Charles. You've given me more things to think about for future projects.
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!
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?
Very nice project.loved your work men..👌👍.
Great content, thanks
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
can you make that audio player connected in a Bluetooth via MIT APP INVENTOR?
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.
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?
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
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.
@@thelastoutpostworkshop right on, thx.. seems like too much extra when it's damn close 💯
.. great work BTW.. that was the exact post I needed, the BUSY pin was totally unknown to me till now 👍
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?
try format your SD card with www.sdcard.org/downloads/formatter/
@@thelastoutpostworkshop did that. I forgot to mention, sorry
Copy your code here
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
try this : mp3.stop();
didint work with if :(
copy the whole section of the code
@@thelastoutpostworkshop sorry I had a problem. I couldn't answer. stil not working This shit ain't gonna stop.😂. You don't have any other code ?
Are you a Star Wars light side fan or dark side?
Both!
SoftwareSerial haa been dead forca long time.
