Note: For simple use ,the upper diagram is ready,But if you find the noise is quite loud, then you could attach an 1K resistor to the TX pin. Note: short time press means pre/next,and long time press means vol- ,vol + Connection Diagram Here comes the most simple way to use this module. Get AD Button from DFRobot Store or DFRobot Distributor. We use the AD module keys, instead of the traditional method of matrix keyboard connection, it is to take advantage of increasingly powerful MCU AD functionality, Our module default configuration 2 AD port, 20 key resistance distribution.

Support for asynchronous serial communication mode via PC serial sending commands The automatic broadcast equipment, regular broadcast.Electromechanical equipment failure alarm.The electric tourist car safe driving voice notices.Multi-channel voice alarm or equipment operating guide voice.The public security border control channel voice prompts.Vehicle into and out of the channel verify that the voice prompts.Electricity, communications, financial business hall voice prompts.Railway station, bus safety inspection voice prompts.Road transport inspectors, toll stations voice prompts.30 level adjustable volume, 6 -level EQ adjustable.audio data sorted by folder, supports up to 100 folders, every folder can hold up to 255 songs.when advertising is over in the music continue to play advertising sound waiting function, the music can be suspended.A variety of control modes, I/O control mode, serial mode, AD button control mode.Fully supports FAT16, FAT32 file system, maximum support 32G of the TF card, support 32G of U disk, 64M bytes NORFLASH.24 -bit DAC output, support for dynamic range 90dB, SNR support 85dB.The module can be used as a stand alone module with attached battery, speaker and push buttons or used in combination with microcontrollers such as Arduino, ESP32, Raspberry Pi and any microcontrollers with Uart. Since you seem to be using regular LEDs, I'd use an array to hold the status (on or off) of each LED.The DFPlayer Mini MP3 Player For Arduino is a small and low cost MP3 module with an simplified output directly to the speaker.

The numbers 6-10 are just example numbers - modify to what you're using. I'd define the PINs for that something like so: #define LEDPIN1 6 If however all LEDs are already off then the new scenario should be applied. If at least one of the LEDs isn't off, then the LED matching the switch should be switched off.

Once a scenario is selected, I'd imagine that the code waits for a key to be pressed. How does the user select a scenario? By pressing one of the Sx buttons? I'm not sure how far you've gotten with the code. Please help me with the logic and the code to make this work. User presses S1 which will turn off L1, similarly S3 will turn off 元 and S4 will turn off L4. User presses S2 which will turn off L2, similarly S3 will turn off 元 and S5 will turn off L5. User presses S1 which will turn off L1, similarly S3 will turn off 元 and S5 will turn off L5. User presses S1 which will turn off L1, similarly S2 will turn off L2 and S4 will turn off L4. System must take the input from the user. The circuit is intended to function as below:
