DFplayer cannot communicate with Arduino Nano
Account cancelled 2021-11-24 12:59:20 514 Views1 Replies I have the DFplayer on a breadboard, connected to an arduino Nano just like the product wiki suggests via the RX/TX pins on the player, and the corresponding pins on the Nano for the test code I am using. All the code does is plays a sequence of sounds every couple of seconds.
When I have it connected, nothing happens.. no lights on the player, no sounds.
I can only get the sounds to play if I ground the IO pins on the player. I've tried using a different Arduino board to no avail. I have a 1K resistor on the TX line.
Maybe I'm missing something?

I had the same problem when trying to connect the DFPlayer Pro to a nano every board. Rx-Tx connected to pins 2-3 of the nano every. No Serial communication could be established from the nano to the DFPlayer Pro. I changed to an Arduino UNO, and everything worked at once.
I assume the Nano boards don't have the same serial communication pins as the Uno. However, i haven't found which pins do allow the communication with the DFPlayer Pro.
Have you found a solution since?
