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. ContentsIntroduction of Pins

UsageBasic FunctionalityThe Buzzer Trinket is a simple trinket which emits sound when passed with a frequency. A Core module can control the frequency of the Buzzer output.
ProgrammingIntroductionThe 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
ExampleThis is a simple example which:
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);
