MEMS MICROPHONE ON BREAKOUTBOARD COM-MIC-ADMP401 1. GENERAL INFORMATION Dear customer, thank you very much for choosing our product. In the following, we will introduce you to what to observe while starting up and using this product. Should you encounter any unexpected problems during use, please do not hesitate to contact us.

2. USAGE WITH THE RASPBERRY PI For use with the Raspberry Pi, you need an analog-digital converter. For this purpose, you can use our product COM-KY053ADC. You can find more information about this product here.

For the following code example, you need a operating system with graphical user interface. We recommend Raspberry Pi OS with desktop and recommended software. First, enable I2C on your Raspberry Pi. To open the configuration, enter sudo raspi-config There, select 3 Interface Options → P5 I2C. There, you get the question Would you like the ARM I2C Interface to be enabled? Confirm this with Yes. You have now successfully activated I2C. The analog-digital converter is now accessible under the I2C address 0x48. We use the Adafruit_Python_ADS1x15 library for our code example, which is released...

Now install the required software with the following commands. sudo pip3 install -U matplotlib sudo pip3 install -U numpy sudo apt-get install libatlas-base-dev Now download and unzip the code sample. wget https://joy-it.net/files/files/Produkte/COM-MIC-ADMP401/ COM-MIC-ADMP401_RaspberryPiCode.zip unzip COM-MIC-ADMP401_RaspberryPiCode.zip You can now run the code example with the following command. You will see a graph that records the volume fluctuations. python3 COM-MIC-ADMP401.py

3. USAGE WITH THE ARDUINO

Now, copy the following code into your Arduino IDE. int pin = A0; int value; void setup() { // put your setup code here, to run once: Serial.begin(9600); } void loop() { // put your main code here, to run repeatedly: value = analogRead(pin); Serial.println(value); } Click on Upload to run the program. However, make sure that Board and Port are selected correctly under Tools. Under Tools, click on Serial Plotter to display the read-out values of the microphone graphically.
