Sensor-Buzzer

The product number of Sensor-Buzzer is: MSDO11

Sensor-Buzzer is a passive buzzer. Like a magnetic speaker, it needs voltage with different frequency so that it can make sound accordingly. The pitch becomes louder when the frequency gets higher.

  • General Pin Out is the standard pin out of a Sensor / Trinket connector.
  • Sensor / Trinket's Pin Out is this specific Sensor / Trinket's wiring in relation to the General Pin Out.
  • SIGNAL-A / SIGNAL-B are signals that could be digital input, digital output, analog input or analog output. Or special signals such as serial communication (SoftwareSerial, IIC (I2C), etc) or other special signals.
  • Not Connected refers to the Pin not being used for this particular Sensor / Trinket.
  • Read more about the hub module.

Programming

Introduction

The LED Trinket is used as a simple output pin. Therefore, the pinMode and digitalWrite functions will be used.

Key Functions

  • Required Libraries: None
  • Key Functions:
    • pinMode(pin_number, pin_mode) - sets the mode for the pin
      • pin_number - is the pin number that the trinket is connected to
      • pin_mode - is the mode to set the pin to. Either INPUT or OUTPUT
    • digitalWrite(pin_number) - Changes the state of the pin either to HIGH or LOW
      • pin_number - is the pin number that the trinket is connected to

Example

This is a simple example which turns on and off the LED at 1 second intervals.

Note: Important lines of code are highlighted. 

//Define the pin the sensor is connected to
const int LED_PIN = 6;

void setup() {
  // put your setup code here, to run once:

  //Initial serial communication port at 9600 baud
  Serial.begin(9600);

  //Configure the pin into output mode
  pinMode(LED_PIN, OUTPUT);
}

void loop() {
  // put your main code here, to run repeatedly:

  //Perform a digitalWrite with HIGH to turn on the LED
  digitalWrite(LED_PIN, HIGH);

  //Delay 1 second
  delay(1000);

  //Perform a digitalWrite with LOW to turn off the LED
  digitalWrite(LED_PIN, LOW);

  //Delay 1 second
  delay(1000);
}

Copy and paste the code above to the Arduino IDE or

Download the above example: n/a

Program Download

Programming

  • Follow the Software Getting Started Guide.
  • Select the Board, Processor and Port.
  • Click [File]->[Open], browse to the project program address, and click "Sensor-Buzzer Test.ino" to open the program.
  • After confirming all these items are correct, click "→" to download the program to the development board.

Hardware Setup

  • Referring to the following diagram, connect the Sensor-Buzzer to digital pin D6 of Microduino-Sensorhub.

Result

  • After download, you can hear the alarming sound.

Application

The buzzer can produce many weird sound. Maybe you can add some keys to it to compose a piece of wonderful music.
