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. Read more about the hub module. Features Controllable sound frequency (eg: You can achieve the effect of piano spectrum with it. ) Small size which is easy to install. Specification Voltage 3.3V~5V working voltage Size Size of the board: 23.5mm*13mm 1.27mm-spacing 4Pin interface connected with sensorhub. The CAD drawing of the sensor: File:Sensor CAD.zip Technical parameters Drive with 2K~5K square wave The sound frequency is controllable. Connection This sensor can be connected to the following interfaces of core: A0~A7,D2~D13 Document Schematic diagram: File:Sensor-Buzzer.Zip Usage Basic Functionality The 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. Buzzer Trinket State Table Pin State Buzzer State No Frequency No Buzzing Frequency Present Buzzing Programming Arduino for MicroduinoArduino for Microduino 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 Download and unzip the program File:Sensor-Buzzer Test.zip 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.
