Dear @VictorSalendu, Thank you very much for your encouraging words. Glad to know that you liked my content. Best Regards

​And would you mind writing a short code for me:_) I'm a newbie and want to complete my project because it has too little documentation about this module and still don't know how to share the I2C bus with multiple devices. Thank you so much, Sir.

Dear dũng nguyễn @dungnguyen-si2sz Thank You very much for your encouraging words. This device (DFRobot Gravity: Voice Recognition Module) boasts high compatibility, supporting both I2C and UART communication methods. As You want to connect _"this module with the I2C communication together with 1 OLED display"_ For your query there are *two* approaches/solutions - 1. You can use UART interface for Voice Recognition module and I2C interface for OLED display ==> We know (from WiKi page of this Voice Recognition module) that to use I2C or UART for this module you have to just declare the your communication interface initially in the code. Like following - //I2C communication DFRobot_DF2301Q_I2C asr; //For UART use as per availability of serial ports #if (defined(ARDUINO_AVR_UNO) || defined(ESP8266)) // Use software serial SoftwareSerial softSerial(/*rx =*/4, /*tx =*/5); DFRobot_DF2301Q_UART asr(/*softSerial =*/&softSerial); #elif defined(ESP32) // Use the hardware serial with remappable pin: Serial1 DFRobot_DF2301Q_UART asr(/*hardSerial =*/&Serial1, /*rx =*/D3, /*tx =*/D2); #else // Use hardware serial: Serial1 DFRobot_DF2301Q_UART asr(/*hardSerial =*/&Serial1); #endif 2. If you want only I2C interface for both the module(Multidevice on I2C) then you just to need declare two separate objects for both I2C devices like following-- //I2C declaration For Voice Recognition Module DFRobot_DF2301Q_I2C asr; //I2C declaration for I2C display Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, -1); To initialize I2C OLED display in setup function you need to do -- //----------------------------------------------------------// if(!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) { Serial.println(F("SSD1306 allocation failed")); for(;;); } //----------------------------------------------------------// And To initialize Voice module //----------------------------------------------------------// while( !( DF2301Q.begin() ) ) { Serial.println("Communication with device failed, please check connection"); delay(3000); } Serial.println("Begin ok!"); //----------------------------------------------------------// Library of Voice module will take care of its I2C address. Please go through following projects and their codes, you will get idea how you can achieve your goal 🔗 www.hackster.io/dipowin/voice-controlled-digital-cute-pikachu-9148e9 🔗 www.hackster.io/517133/voice-controlled-dht11-with-dfrobot-43a41c You can always refer WiKi of this Voice Recognition module where they have given the codes for both the interfaces. 🔗 wiki.dfrobot.com/SKU_SEN0539-EN_Gravity_Voice_Recognition_Module_I2C_UART Beside if you still have any doubts, feel free to ping me. I'll try my best to help you. Best Regards

Hello, apologies for late reply. Yes, with DFRobot Offline Voice Recognition board you an set custom set command words and Wake words in any language. But the prompt(/responses) will only in English since they are pre-programmed. Best Regards

You're most welcome. Glad you liked this content. Best Regards

Reset it by, Deleting all wake-up and command words. Use default "Hello Robot" wake word after reset. There are commands to delete the command and custom wake words. like, "I want to delete" Check out following wiki for more details - wiki.dfrobot.com/SKU_SEN0539-EN_Gravity_Voice_Recognition_Module_I2C_UART

No, it does not have any 'inbuilt AI'. This Gravity Offline Voice Recognition Sensor is built around an *offline voice recognition chip*, which can be directly used without an internet connection. It comes with 121 built-in fixed command words and supports the addition of 17 custom command words. Meanwhile, this voice recognition module compatibility with multiple common controllers enables it to provide a flexible solution for makers and electronics enthusiasts in terms of voice interaction. It can be applied to any application that requires voice control or interaction, such as various smart home appliances, toys, lighting fixtures, and robotics projects, among others.

I think not possible. Since this module primarily designed for voice recognition. Detecting sound can be possible but false detections can possible. But you can try by training it for siren sound, let me know your findings. can we increase the audio/voice listening capacity of the module? No, Its "non-modifiable design" or "non-reconfigurable design." We have to use external augmentation to modify its behavior.

Sir pls do reply

Hello Abhiram, apologies for late reply. Product/module purchase links are given in the description. Also, detailed component list is given in Hackster Article. Best Regards

Dear Prem Raj, This project was developed and submitted for Arduino CloudGames Project contest. Unfortunately I did documented any DIY process of development of this project. Due to deadline of contest submission I only recorded demo video. But I can help you with your project. Please let me know your queries.
