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 LED Trinket is used as a 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 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);
