I would like to operate 5 DFPlayer with one Arduino Uno. If 5 is not possible in any way, the maximum which is possible (4?, 3?,)
I understand that I need to create new serial port, but I couldn’t find exactly how to do it and use them for the DFPlayers.
I don’t need Tx, only Rx (i.e. I only want to send WAV files to the DFPlayer to play, but I don’t need a feedback on the status of the DFPlayers.
Is it possible? if Yes, can someone suggest how to do it?
