Sound FX Project Help

by convoy on Fri Dec 03, 2021 2:46 pm

Hello,


I was wondering if anyone might be able to point me in the right direction to upgrade a previous project. I created a PA system for my car incorporating the Adafruit Sound FX board (16mb). It works great but I would like to have access to more sounds.

Is there any way to add flash storage to the board or can it access external memory like a microSD card?

If not, I have some limited experience with Arduino/CircuitPython/Raspberry Pi. I guess I would like to use a microcontroller to play the files in a similar way but this time using a rotary encoder and LCD screen to select from many sounds to play. I’m not very good at creating code from scratch but I can sometimes modify and combine things from other guides and videos. Does anyone know of a similar project that could help with menu selection and display that I could combine with audio playback?

Any help would be greatly appreciated, Thanks!

I have included photos of my current design if anyone is curious.

I’m afraid not. That one was designed as an easy all-in-one solution for things like props and toys.

It sounds like you’re ready to bump the project up to a Music Maker:

https://www.adafruit.com/?q=music+maker&sort=BestMatch

That one is an MP3 codec that can read data from an SD card. We have several sample projects over in the Learning System:

Hi!

Thanks for the advice. I have now purchased the music maker but I am having some trouble getting it working. After following all the steps I can't get it to work. Anyone have any idea what I could do or what I am doing wrong? Any help would be greatly appreciated!

I get no sound at all. I get nothing in the serial monitor, not even errors. I double checked the solder joints and checked the headers for continuity and everything looks good. It seems like a code problem because I can get other sketches to run correctly, specifically a serial monitor test.

I also tried the VS1053 "player_gpiotest" and it also doesn't work, same-nothing in serial monitor.

Some info and code below

I am using the Music Maker #1790 connected to the Metro M4 # 3382.

To get started I have been following the Music Maker Guide here:
https://learn.adafruit.com/adafruit-mus ... bis-player

I soldered on all the headers and the 6-pin socket. I installed it on the Metro M4.
I then installed the latest version of the Arduino IDE.
I installed the Adafruit SAMD Boards and Arduino SAMD Boards libraries. I installed the VS1053 library.

I wanted to start with the "player_simple" example code in the library so I followed the guide. I commented and uncommented the appropriate lines to indicate in the code that I am using the shield. I copied two mp3 files(named track001.mp3 and track002.mp3)to a microSD card and put it in the shield. I verified and uploaded the code to the Metro M4 successfully. I plugged in a 3.5mm cable and connected it to a powered speaker.

Let's start by checking the connections. Post a photo showing your hardware and connections and we'll take a look. 800x600 images usually work best.

I have now tested the music maker shield with an Arduino Uno R3 clone (with ATMEGA328) that I had laying around and it works fine. I was just hoping to use it with the Metro M4. Do you happen to know if I would need to modify the code or include more libraries to work with the Metro?

I also tested the Metro with a few basic example sketches and it seems to work fine with other code. I also tried bridging the ICSP pads but still no change so I de-soldered them.

The only changes you need to make will be the GPIO pin numbers at the top of the sketch. The M4 already knows its SPI pins, but you'll need to match the others.
