Hello friends, I hope you all are doing great. Today, I am going to share the new DFPlayer Mini Library for Proteus V1.0 . The DFPlayer Mini is the tiny MP3 player module with a micro SD card slot that so many Arduino projects use for a voice that says "welcome home", a door bell, an alarm or background music. The Arduino sends it short serial commands - play file 4, volume 20, next - and the module does the rest: it reads the card, decodes the MP3 and drives a speaker. In a simulation it was hard to try, because Proteus has no such part and no card to read. Behind the parts sits our own model , written from the datasheet of the module. It answers the 10-byte 7E FF 06 frames at 9600 baud, needs its 0.8 s to start, plays the files of a demo micro SD card - 14 short tracks in folders 01 and ...
