Mastering MP3 Player Busy Pin with Arduino & Audio-Visual Synchronization

[@robgreen7702]

Excellent tutorial. Well paced and easy to follow with plenty of visual aids.

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

[@thelastoutpostworkshop]

thanks a lot

[@Mokkers_stuff]

Excellent video, easy to follow, clearly explained and no annoying background music to distract you! Thanks for uploading and, yes, I made it to the end. 👍

I enjoyed adding the functionality of the MP3_Rotary with the features of this MP3_busy_pin allowing me to use the rotary encoder. It was a good experience figuring out the library differences and how to incorporate the logic between the two sketches. Thank you.

[@DAveShillito]

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 👍

[@raimundtrierscheid6318]

Super video with very structured and helpful explanation of code and wiring - all thumbs up !!

[@thelastoutpostworkshop]

Many thanks!

[@yorha2b278]

Yeah, I made it all the way to the end. Keep sharing your great work.

You are a life saver now i can use it more efficiently in my home assistant project on science fair

[@brucewoods9377]

Great video. Very informative

[@ytenyusuf]

Sorry sir, if the sound input comes from the original buzzer out of the car parking sensor, how do i wire it and code it? 🙏 thanks

[@DatFunnyPerson]

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?

[@paulmarkert5907]

This is a great video, thanks for putting it out there. I cannot replicate the behavior you have around the Busy PIN (minute 7:44) without removing the resistor/LED path from the circuit, though. Once I do, I get 'Busy Pin=1' and the "Audio file finished playing" message. I am not sure why I don't have enough voltage to trigger HIGH and power the LED path at the same time. I am connected to the 5V power, so that shouldn't be the issue. I now suspect I may have a defective DFPlayer mini and have ordered some new MP3-TF-16P players to see if that is the issue.

[@thelastoutpostworkshop]

Have you tried measuring the voltage with a multimeter ?

[@paulmarkert5907]

@thelastoutpostworkshop not yet. I will try that in a couple of days.

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?

[@ShayanBinShad]

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?

[@thelastoutpostworkshop]

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.

[@6rilBemane]

Hi, Can you help me with my project with my DFplayer?

[@DaveHoran]

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.

[@thelastoutpostworkshop]

Wow great project! Thanks for sharing

[@tom95076]

Thank you for this. I watched the entire video and enjoyed the detail within it.

[@thelastoutpostworkshop]

Awesome, thank you!

[@Bochets34]

Well done❤. Just curious: which SW tool do you use for drawing the wiring at the beginnin (step by step 2nd chapter). This is awesome

[@thelastoutpostworkshop]

Thank You. I am using Adobe After Effects

[@whoopzKERRY]

can you make that audio player connected in a Bluetooth via MIT APP INVENTOR?

[@buildersmark]

Can this be ran with an ESP32 Wroom controller instead of the Uno?

[@thelastoutpostworkshop]

Yes

[@buildersmark]

@thelastoutpostworkshop I keep trying by using gpio 26/27 for the rx/tx, (& I int those pins) but never get the ESP to communicate to the DFPlayer. I know it has to be something in code, but not sure. Thank you for responding.

[@livetohash6152]

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?

[@thelastoutpostworkshop]

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.

[@livetohash6152]

@@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 👍

[@LowerDeckProps]

Good video, Charles. You've given me more things to think about for future projects.

[@gameworld2945]

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

[@thelastoutpostworkshop]

try this : mp3.stop();

[@gameworld2945]

didint work with if :(

[@dinutaciofu5107]

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?

[@thelastoutpostworkshop]

try format your SD card with www.sdcard.org/downloads/formatter/

[@dinutaciofu5107]

@@thelastoutpostworkshop did that. I forgot to mention, sorry

Great vid, gonna use it ... a suggestion for your very good English 'Busy' is not said as 'Buzzy' it is a ' B ih zzy' like silly or willy, missy, kissy or Milly. 'Fizzy' is the best comparison, fizzy, busy ,fizzy, busy they rhyme - English is nuts, sorry lol

2:00 mine works just fine with 128Gb card.

[@leeskelton9715]

Great content, thanks

[@leeskelton9715]

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
