Joy-it Mems Microphone On Breakoutboard Instruction Manual

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.

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.

Connection

Installation

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 under the MIT- Lizenz. Use the following commands to download and install this library.

• git clone https://github.com/adafruit/Adafruit_Python_ADS1x15.git
• cd Adafruit_Python_ADS1x15/
• sudo python3 setup.py install
• cd ..

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

Code example

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

USAGE WITH THE ARDUINO

Connection

Code example

Now, copy the following code into your Arduino IDE.

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.

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);
}
