Menu with voice & rotary encoder - Arduino

Best & Fast Prototype ($2 for 10 PCBs): https://www.jlcpcb.com
Thanks to JLCPCB for supporting this video.


This is a small example of how to use a rotary encoder to scroll the menu. How to create special unique characters for the i2c LCD screen and how to play Mp3 files with the DFplayer module. You have all the files you need below.
