I'm new to the arduino community, i was trying to make chatbot EVE https://www.instructables.com/Eve-the-Arduino-Chatter-Bot/ from this link but then i realised that the sound module was not available near me so i bought dfplayer mini, and i did some changes in the code.
The Code:-

i have arduino uno and nano both have only 1tx and rx and i wanted to use hc05 and dfplayer, after all the chnages it was verified / compiled and i uploaded to my arduino and did the appropriate wiring but then my lcd which should have shown emotions is not showing anything and no audio file been played after connecting to hc05. what i have done wrong?
