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.

Introduction

The Buzzed Trinket is used as an output pin. Special functions on the Core module is used to generate a frequency signal to the Buzzer.

Key Functions

  • Required Libraries: None
  • Key Functions:
    • tone(pin_number, frequency) - starts generating a frequency signal on the pin, will not stop until noTone(pin_number) is called (Read more)
      • pin_number - is the pin number that the trinket is connected to
      • frequency - a frequency value to generate on the pin
    • noTone(pin_number) - stops generating a frequency on the pin (Read more)
      • pin_number - is the pin number that the trinket is connected to
    • tone(pin_number, frequency, duration) - generates a frequency signal on the pin for a set amount of time (Read more)
      • pin_number - is the pin number that the trinket is connected to
      • frequency - a frequency value to generate on the pin
      • duration - the duration in milliseconds to generate the frequency signal

Example

This is a simple example which:

  • Starts the Buzzer at a 440hz frequency.
  • Waits 1 second.
  • Turns off the Buzzer.
  • Wait 1 second.
  • Runs the Buzzer at a 294hz frequency for 2 seconds
  • Waits 5 seconds.

Note: Important lines of code are highlighted. 

//Define the pin the buzzer is connected to
const int BUZZER_PIN = 6;

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

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

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

  //Start the Buzzer with a 440hz frequency
  tone(BUZZER_PIN, 440);
  //Wait 1 second
  delay(1000);
  //Turn off the Buzzer
  noTone(BUZZER_PIN);

  //Wait 1 second
  delay(1000);

  //Run the Buzzer with a 294hz frequency for 2000 milliseconds (2 seconds)
  tone(BUZZER_PIN, 294, 2000);

  //Wait 5 seconds
  delay(5000);
}

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
