DFPlayer mini reset when speaker is connected
Account cancelled 2017-11-21 01:24:06 2680 Views0 Replies Hi,
I use the module DFPlayer mini with an arduino pro mini 3.3V.
DFPlayer works fin when i use DAC_L/DAC_R pins. But when i connect a speaker to SPK1/SPK2 it doesn't work. I listen a huge noise and my arduino reset at the line myDFPlayer.begin(mySoftwareSerial).
I don't know why.
