Hi All,
I am putting together a mp3 player based on DFPlayer. Initially it was playing consistently. But now it is very erratic and only plays intermittently
The following links are what i have put together for setting up the LCD and DFPlayer in a single sketch
Software serial for DFPlayer is on 5,6 rather than 10,11.
When i let the dfplayer and lcd load and then connect the speaker, it works sometimes.
But when i connect the speakers and the connect to usb, I get weird noise(as in the video) and then it refuses to start
Can you please help me? Is this the voltage drop issue?
Not much to see on that video, as you forgot to show the things that count. That speaker is rather unimportant.
I didn't see a ground connection between the ground pins of the DF player.
I didn't see resistors in the Tx and Rx lines.
I didn't see a decoupling capacitor for the DF player.
That are all common things you need to make the thing work well. That, and of course an appropriate power supply.
