i try to use, two ports in arduino ATmega328p, the first port it control the DFPlayer mini, and the second port, it control Bluetooth module HC-06, but not work, in serial monitor show me this message:
My project Initializing DFPlayer ... (May take 3~5 seconds) Unable to
begin:
1.Please recheck the connection!
2.Please insert the SD card!
but when I delete the Bluetooth code fragment , the project work fine with DFPlayer mini module.
how i would connect two modules, because i try with the sample code of arduino page, but not work for me
