₹100-400 INR / hour

PLEASE NOTE:- I'm working with ESP32 for the first time, I have 3-4 months experience with Arduino Story- I was trying to play an mp3 audio using ESP32 and DFPlayerMini but every time it shows these two errors:- Unable to begin: [login to view URL] recheck the connection! [login to view URL] insert the SD card! Link for the code is available at GITHUB I know only these things about it- The SD card is inserted and working perfectly with ARDUINO UNO. The Rx and Tx is causing the problem (I'm using p16 and p17 as Rx and Tx respectively) also, I tried interchanging the Rx and Tx but no luck. I don't know what is the model of the board as I purchased it from a local store but I know this (I could understand these only) - ESP WROOM 32 ESP 32S ESP Dev Module (I uploaded the code with this and the code was uploaded) The Pins are not like shown in the pinouts available online; For eg - I got to know that P16 and P17 are the Rx2 and Tx2 Please help me with this supposing me to be a dumb newbie :) Thanks
