多功能智能播放器—电路设计

Multifunctional smart player-Circuit designAbstractThe multi-functional smart player designed in this paper has a variety of controlmodes,including key control,voice control and mobile app control.This papermainly introduces the circuit design of each module used in the multi-functionalintelligent player.The selected control platform is Arduino Mega 2560,and themodules with the required functions are selected according to the functions to berealized.First,dfplayer module with playback function is required Mini andloudspeaker;second,the player needs to be controlled by voice interaction,so thevoice recognition module ld3320 is selected;third,the player needs to be controlledby mobile app,so the hc-06 Bluetooth module is selected;finally,the songs and tasksthat are currently playing and executing need to be displayed,so the 0.96 inch OLEDof lIC interface is selected.After selecting the original,learn the module instructionand design the circuit,and finally check whether the test circuit is correct.Keyword:Arduino:Smart play:Voice interaction:Mobile control;OLED display:Circuit design
