The reference to 37 sensors and actuators has been widely circulated on the Internet. In fact, there must be more than 37 sensor modules compatible with Arduino. In view of the fact that I have accumulated some sensor and actuator modules on hand, according to the concept of practicing true knowledge (must be done), for the purpose of learning and communication, I am going to try a series of experiments one by one, regardless of success (the program goes through) or not, They will be recorded - small progress or unsolvable problems, hoping to inspire others.
[Arduino] 168 kinds of sensor module series experiments (data code + simulation programming + graphics programming)

• Supports loading WAV audio format;
• You can freely combine voices through professional PC operating software, and you can insert mutes, which do not occupy the capacity of the memory. Loading sound can be repeatedly called to multiple addresses;
• USB download method, support online download/offline download; even when the WT588D voice chip is powered on, it can also download data to SPI-Flash normally; • Support MP3 control mode , key control mode, 3×8 key combination control mode, open port control mode, one-line serial port control mode, three-line serial port control mode and three-line serial port control I/O port expansion output mode; • Switch from three-line serial port control mode to three-line serial port control
I The /O port extended output mode can be switched only by sending data. After switching, the last working state before switching can still be brought into the working mode after switching;
• Arbitrarily set the BUSY output mode for displaying the voice playback state signal;
• Strong anti-interference, can be used in industrial fields;
• 220 segments can be Control the address bits, a single address bit can load up to 128 voices, and the voices in the address bits are played in combination;
• Supports trial listening to the loaded voice playback;
• Stops the voice playback and immediately enters sleep mode, and the chip turns to a complete stop state;
• 15 button control modes, any button can be set to any control mode;
• Matching WT588D VoiceChip PC software, simple interface, easy to use. It can maximize the functions of the WT588D voice single-chip microcomputer;
• The simple writing method of the single-chip microcomputer, get rid of the complex and cumbersome compilation thinking;
• A single chip supports multiple external
memories ; ;
• The mute time range of insertion is 10ms~25min;
• The chip reset time is 5ms;
• The working voltage is DC2.8V~5.5V; • The static sleep current
is less than 10uA ; (This feature is yet to be opened).
Function overview of WT588D voice module
It is a powerful voice microcontroller chip that can be repeatedly erased and programmed. WT588D makes the voice chip no longer need to find a suitable peripheral single-chip circuit for the control method, and the highly integrated single-chip technology is sufficient to replace the complicated peripheral control circuit. The WT588D VoiceChip upper computer operating software can be used to change any control mode of the WT588D voice microcontroller chip at will, and the information can be downloaded to the SPI-Flash. The operation mode of the software is simple and easy to understand, and it matches the voice combination technology, which greatly reduces the time for voice editing. It fully supports online downloading. Even when WT588D is powered on, you can also download information to the associated SPI-Flash through the downloader, and reset the circuit of the WT588D voice chip to update to the control mode just downloaded.
1. Support inserting mute mode, inserting mute does not occupy the capacity of SPI-Flash memory, one address bit can insert 10ms~25min mute; 2.
Under MP3 control mode, it fully caters to the MP3 play/pause, stop, previous on the market Song, next song, volume +, volume - and other functions;
3. In the key control mode, the trigger mode is flexible, and any key can be set as pulse repeatable trigger, pulse non-repeatable trigger, invalid key, level keep non-circular, power Level hold can be cycled, level non-hold can be cycled, previous track not cycled, next track not cycled, previous track cycled, next track cycled, volume +, volume -, play/pause, stop, play/ There are 15 trigger modes such as stop, and at most 10 keys can be used to
trigger the control output; 4. In the 3×8 key combination control mode, 24 address voices can be triggered in a pulse-repeatable way, and the triggered address voice can be in the range of 0～ 219;
5. Parallel port control mode can be controlled by 8 I/O ports, only limited to WT588D-32L, WTW-28P; 6.
One-line serial port control mode can control voice playback, stop, loop playback and Volume level, or directly trigger any voice of address 0~219, the code sending speed is 600us~2000us;
7. The three-wire serial port control mode and the three-wire serial port control I/O port expansion output mode can be switched by sending codes, and the three-wire serial port control In this mode, it can control voice playback, stop, loop playback and volume, or directly trigger any voice from 0 to 219 address bits. The three-wire serial port control I/O port expansion output can expand the output to 8 bits, and switch between the two modes. It can keep the latter state of the previous mode and enter the next mode;
8. PWM and DAC output mode, PWM output can directly drive 0.5W/8Ω speakers, DAC output is connected to an external power amplifier, and the sound quality is good.
It has a wide range of applications and can be used in almost all voice places, such as station announcers, alarms, reminders, alarm clocks, learning machines, smart home appliances, therapeutic devices, electronic toys, telecommunications, reversing radar and various automatic control devices, etc. , The process meets the requirements of industrial applications.
