5 months ago Hi, I'm glad you were inspired by my project. There are an incredibly large number of DF Player clones. I bought 8 of them from 8 different stores for testing purposes and each one is different in some way. I would put it down to the chip version. It is possible that it will take more time to initialize, for example, or take larger pauses between commands.
Start by uncommenting the directive in the DFPlayer.h file on line 7:
#define _DEBUG.
Here direct link to that line: https://github.com/ByPS128/Arduino-Aliens-M41A-Riffle/blob/a8250e9c2921058aded1581b83136675a5db8e98/src/M41A/DFPlay.h#L7
Upload the program to the arduino and then connect to the arduino's serial line by activating Serial Monitor. This is done with the icon on the top right.
The arduino will reboot and the bottom of the Arduino IDE will start listing what the application is currently doing. Most of the information is from the DF Player. Without a doubt, the communication with the DF Player is the most sensitive part of the whole assembly.

This is what communication looks like with DF Player, which works well. Try to compare the outputs. Or if they differ, put your output here.
The following constants are in the DFPlay.h file:
static const int DFPLAYER_RESET_TIME = 1000; static const int DFPLAYER_INIT_TIME = 500;
You can try experimenting with their values. The values are in milliseconds.
There are more options to play around with, but let's start with the dump ;)
A little tip, if you have the serial monitor on and want to re-upload a new version. you need to deactivate the serial monitor first. I often forget this and the upload fails afterwards.

Hi @ByPS128 First of all, thank you so much for putting this amazing project together!
I'm currently putting together a prototype of the board, just wanting to use a single button for pulse rifle fire as a test. However, I am having issues getting the sound to play when I press the A2 trigger button (the ammo counter works as expected).
I have verified that the DF player works and the sounds are played if I trigger IO pins on the DF module. I have followed your instructions on the directory for the sounds.
I am stumped on what else to try so I hope you can help!
Thanks again for this amazing project!
