# Resister Optional The 1k resister shown on the blue TX (transmit) circuit in dfplayermini_connect_MMBC2nJ6K8.jpg is optional. It reduces the sound levels. # Website https://wiki.dfrobot.com/DFPlayer_Mini_SKU_DFR0299 # Github link to DF player mini code - https://github.com/DFRobot/DFRobotDFPlayerMini

That is not the reason for the resistor. The TX line carries a digital signal, which has no concept of resistance. The resistor is to protect the 3.3v RX input from excess current when connected to a 5v output pin. From section 4.1 of the DFRobot data sheet: *4.1 Serial Communication Connect "Module's serial port is 3.3V TTL level, so the default interface level is 3.3V. If the MCU system is 5V. It is recommended connect a 1K resistor in series."*

It didn't work for me at all. when I compile my code nothing happening. The name of my sound is 0001_right.mp3 and I don't know what the problem is.

From what I have read file names need to be 0001.mp3, 0002.mp3, etc. I think the "_right" is messing it up. Rename it to 0001.mp3. I am not sure how important the folder name is, but I put mine in a folder named mp3 and they seem to work OK.

I followed these instructions and I get a 'click' sound from my speaker and nothing else. I am uaing a simple 2w 8/ohm speaker . I get an "ok" on my serial monitor . Any ideas ? Thanks , Jonathan.

Your program will be used to set up sound affects for my brother in-laws Star Wars "Gonk Droid". Cheers!

The setup works for me, mostly. However the volume is very faint. I can barely hear it over my “quiet board” 3D printer. I have double checked the wiring and everything appears correct. Any ideas on why the volume is so low? I am using an 8 ohm 2 watt speaker. https://smile.amazon.com/gp/product/B08FFLH5XL/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&th=1

anybody getting an error message initializing, change the following: if (player.begin(softwareSerial)) to: if (player.begin(softwareSerial,1,0))
