5.Working Mode:

 1).Power-on playback mode:The power-on playback function needs to short-circuit the T1 solder joint,and the functions of the TC and A1 ports will be invalid.If T2 is not welded,the single song will not play the first song in a loop after power-on.If the T2 point is welded,the single song will play the first song in a loop after power-on.

 2).Human body induction playback mode:the module only stores one MP3 prompt sound.When the module senses the human body,the module outputs a high level,that is,the prompt sound is played.Repeated induction triggering during playback is invalid,and the MP3 prompt sound stops after playing.,After sensing the human body again,the module plays again.

 3).Key-triggered play mode:This application triggers play by pressing the key.The key is used as a common 2-pin switch to achieve power-on function.Therefore,the negative pole of the power supply is connected to the key as a trigger to realize the play function.

  1.1).Button A function:If only one MP3 is triggered,press the button and release it to play,and the playback will stop;if two MP3s are stored,press the button to start playing the first one,the button will not be released,and the playback will end Then release the button to play the second song.

  1.2).Button B function:Press the button to start a single loop playback,until the button is released to stop.

 4).Sensor continuous sensing mode:This mode is mainly for the continuous sensing of the sensor,the voice continues to play,and the playback stops when the sensing is stopped.

  1.1).Use A1 port for connection control,such as diffuse reflection sensor,metal proximity switch and other sensors that can be connected to NPN negative output,as a reminder.

6.Function Port Description:

 1).TC:trigger pin 1,the default is high level.When the module stores 2 songs,after the power is turned on,the low level is converted into a high level,and the first song is played,and the high level is converted into a low level,and the second song is played.If the button is pressed,only one song needs to be played,and the module only stores one MP3.Repeated triggering during playback is invalid until the playback is complete.

 2).Al:trigger pin 2,the default is high level:when the input signal is continuously low,the module will continue to play the first song,and when the input signal is input high,it will stop playing.

 3).T1 solder joint:power-on playback pin,the default is floating,after short-circuiting,switch to the second function,power-on playback mode,TC and A1 port triggering is invalid.

 4).T2 solder joint:Play mode selection pin,if left open,the single song will not be in loop mode.If T2 is shorted,the single track will play in loop mode.(Only valid when T1 is short-circuited)
