Best way to add sound to a project using a by8301-16p?

natty15d · June 6, 2021, 9:41pm

Over the last couple of weeks I've put together a sketch using an Arduino Uno, which i’ll swap out later for the smaller Nano. The sketch controls Leds and their sequence using states, & a small servo motor.

It basically has three stages.

No buttons pressed, servo doesn't move and leds blink slowly
Button A pressed, servo moves 35 degrees and leds blink slightly faster
Button B pressed, servo moves 83 degrees and leds blink really fast

The sketch works without any issue.

What I want to do now is add sound. I have 3 sound files, 01.mp3, 02.mp3 & 03.mp3. I want 1 sound file to play & loop for each of the 3 stages listed above.

I have a BY8301-16p module that I have loaded the 3 sound files onto.

If I take the input pin 1 of the module and draw it to ground, the sound plays through the speaker, but using the rx and tx pins in the Nano, I cannot get the module to work or play the sound.

I’ve tried using this library GitHub - Critters/MP3FLASH16P: Library for the "MP3 FLASH 16P" MP3/WAV player, which didn't work for me

& i’ve also been trying to use this library GitHub - NachtRaveVL/BY8X01-16P-Arduino: Arduino Library for the BY8001-16P/BY8301-16P Audio Module. but i cant get even the simple example sketch to verify to try it out.

I have added a 1K resistor to the TX Nano & per the instructions on the NachtRaveVL library page, I have removed the surface mount resistors on the device at points A, B & C. Everything is on a breadboard & is being powered from the PC usb plugged into the arduino board and the 5v pin of the arduino to the vcc pin of the sound board & the servo motor

I’ve been stuck on this for the last week & i realise it’ll be something that i’ve missed, coded wrongly or just misunderstood.

I REALLY need some advice on how best to wire up the board and the correct code, which library I should be using, or if there is a simple way to add the 3 sound files that I haven't considered, any help would be greatly appreciated by this Arduino newbie.

library GitHub - Critters/MP3FLASH16P
I added the sound file to buttonBstate as a test, no sound played, but the servo constantly cycled rather than move to where it was supposed to go to. Tired adding it to the other 2 states and the same thing happened.

[code]
/*
    This example plays a random file (1, 2 or 3) forever
  It uses the playFile() command so no extra code is needed, it will play another file as soon as the previous one finishes
    If it doesn't work, try reversing the RX/TX wires, (THESE PINS CAN BE CHANGED IN THE CPP FILE I CHANGED THEM TO TX A5 & RX A3 ON THE ARDUINO) as that's probably going to be the most common mistake
    Also check that the player's BUSY line is connected to Arduino pin A4
    Finally check that the player has a speaker connected as well as ground and VCC

Forget about your servo and LEDs and sketch for now. You need to start by just getting the sound module by itself working, then once it's working perfectly by itself you can integrate it into your project.

So disconnect everything except for the sound module from your Uno and then try the "super_simple" example the library came with. Make sure to set up some sound files with the filenames the sketch is expecting.

That sketch is only for use with Arduino boards that have a second hardware serial port. The Uno only has one serial port. For the Uno, you would need to use the library's "SoftwareSerialExample" example, but that also requires you to modify the library source code.

My recommendation is that you focus on one library at a time. So start with trying to get the first library working by itself. If you never have success with that one, then you can switch to trying to get the second library working, again starting with the most simple example and the sound module alone, only switching to integration with your servo and LEDs sketch and circuit once the simple sketch is working perfectly.

Started from scratch & reinstalled Critters/MP3FLASH16P & tried the "super_simple" example. It uploaded to the test Nano board & the TX & RX lights flickered but the BY8301 module didn't play.

I then tried NachtRaveVL/BY8X01-16P-Arduino "SoftwareSerialExample" and uncommented the following as per the recommendation.
// // Uncomment or -D this define to enable use of the SoftwareSerial library.
// #define BY8X0116P_ENABLE_SOFTWARE_SERIAL // https://www.arduino.cc/en/Reference/softwareSerial

It uploaded to the test Nano board & the TX & RX lights flickered and thankfully the BY8301 module played a track, just one track, but that's the best result I've had in over a week.
Now to try to figure out how to make it play specific tracks.
When the module had the A&C surface mount resistors it would play a specific track by grounding out a pin, now the resistors have been removed its changed to play random tracks on the same pin.

I'm guessing that i have to add a Busy pin in the void Setup & what i want the module to do, (play a specific track in a loop) in the void loop section of the "SoftwareSerialExample"?
Thank you for your help

Getting some audio out of the module sounds like real progress to me! Sometimes it just takes that small win to start on the progress that eventually leads to a finished project.
