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.

2.1 Connection

Raspberry Pi KY-053 ADMP401

Pin 1 VDD VCC

Pin 6 GND GND

Pin 2

GPIO 2 (SDA)

SDA -

Pin 5

GPIO 3 (SCL)

SCL -

- A0 AUD

2.2 Installation

For the following code example, you need a operating system with gra-

phical user interface. We recommend Raspberry Pi OS with desktop

and recommended soware.

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 soware with the following commands.

sudo pip3 install -U matplotlib

2.3 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

sudo pip3 install -U numpy

sudo apt-get install libatlas-base-dev

3. USAGE WITH THE ARDUINO

3.1 Connection

Arduino ADMP401

3.3 V VCC

GND GND

A0 AUD

3.2 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);
}
