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 of Pins

Buzzer
General Pin Out Sensor / Trinket's Pin Out
PIN1 (GND) GND
PIN2 (VCC) VCC
PIN3 (SIGNAL-A) Digital Output
PIN4 (SIGNAL-B) Not Connected
  • 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.

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.
