1. Introduction The Grove - Buzzer module has a piezo buzzer as the main component. The piezo can be connected to digital outputs, and will emit a tone when the output is HIGH. Alternatively, it can be connected to an analog pulse-width modulation output to generate various tones and effects.
2.
3. Usage 3.1 Standalone Follow these steps to build a sample circuit using this module but without using any microcontroller: 1. Connect the buzzer module to the output side of your circuit (to the right of the power module). On the input side of the circuit, you may use a range of sensor based input modules (Grove Light Sensor, Grove - Button or Grove - Slide Potentiometer). 2. Power up the circuit. 3.
2. Upload the following sample sketch to make the Buzzer make a beeping noise: // Project Four - Noise maker // void setup() { pinMode(6, OUTPUT); } void loop() { digitalWrite(6, HIGH); delay(analogRead(0)); digitalWrite(6, LOW); delay(analogRead(0)); } 3.3 With TI LaunchPad Playing Music (Buzzer) This example shows how to use the Grove buzzer module to play melodies. It sends a square wave of the appropriate frequency to the buzzer, generating the corresponding tone.
/* Buzzer The example use a buzzer to play melodies. It sends a square wave of the appropriate frequency to the buzzer, generating the corresponding tone. The circuit: * Buzzer attached to pin39 (J14 plug on Grove Base BoosterPack) * one side pin (either one) to ground * the other side pin to VCC * LED anode (long leg) attached to RED_LED * LED cathode (short leg) attached to ground * Note: This example code is in the public domain. http://www.seeedstudio.com/wiki/index.php?title=GROVE_-_Starter_Kit_v1.
} void loop() { for(int i = 0; i < length; i++) { if(notes[i] == ' ') { delay(beats[i] * tempo); } else { playNote(notes[i], beats[i] * tempo); } delay(tempo / 2); /* delay between notes */ } } /* play tone */ void playTone(int tone, int duration) { for (long i = 0; i < duration * 1000L; i += tone * 2) { digitalWrite(BUZZER_PIN, HIGH); delayMicroseconds(tone); digitalWrite(BUZZER_PIN, LOW); delayMicroseconds(tone); } } void playNote(char note, int duration) { char names[] = { 'c', 'd', 'e', 'f', 'g', 'a',
