here the DFplayer pinout
Make sure the RX of the DFPlayer is connected to the TX of your Arduino, and the TX of the DFPlayer is connected to the RX of your Arduino.
yeah the dfplayer rx is connected to pin 16 (with a 1KΩ ish resistor) the tx is directly connected to pin 17 and ground vcc and the speaker wires are definitely correct since it can play songs with bridging the io pins
Unfortunately, the photos are very blurry, all the wires are the same color and it is completely unclear what is connected where.
Is the GND of DFplayer connected to GND of Mega?
Also, the speaker connection looks weird. If I see correct, the speaker wires are connected to SPK_1 and SPK_2 pins.
Isn't it should be a SPK_1 and GND?
Could you take a clear photo of Mega pins and another one of the DFPlayer?
yes, the ground is connected to the arduino. Also, the VCC is connected to the 5v pin of the arduino. I know the picture is not clear but I don't have any other wires to use...Furthermore, yes the speaker is connected to SPK_1 and SPK_2 that's what I have seen
(image only for speaker reference)
Are you sure your DFPlayer and serial port on your Arduino board are working?
On the arduino I don't have any doubts on the df player not so much. I will change it to Serial1 and report back in the afternoon. Which where the pins for serial1?

If your clone has the same microcontroller as the Arduino Mega, here are the pinouts.
RX1-TX1 = Serial 1
RX2 -TX2 = Serial 2
etc.
Yes, it is the same, I have the same board

You haven't had any problems with it right?
I found it fully compatible with original Mega except the size
Ok thanks you
I redit all of my connecions and moved the tx and rx wires to serial1. the problem still presist. I will change the resistor to an actually 1KΩ one and not a bunch of 10Ks in parallel and report back.
Here is the code for reference.

EDIT
Or just change the following single line of your original code, from a second parameter of 'true' to 'false'
if (!myDFPlayer.begin(Serial1, /*isACK = */true, /*doReset = */false)) //Use serial to communicate with mp3.
OK I will give it a shot. I first need to find an actual 1k resistor
What's the resistor? Why it's value is so important?
I have a 1K resistor in place but at the time of testing I didn't have it on hand so I soldered 10 10kΩ resistors in place. Which might be giving me noise
Did you do as I suggested in my post #23 three weeks ago?
Yes no luck but I haven't had the chance to change the resistor. I am almost sure that's my problem, but I just haven't had the time to change it. Too much work with university. That's why I didn't respond with an update.... Sorry😔
Guys, I am back! I have finally finished my uni exams and am back to the project. I want to try to get it to work on an Arduino Uno
after testing it still will not work on wednesday i will go get a new one i may have accidenatally fired this one
