Passive Buzzer Module KY-006

passive buzzer module KY-006 โมดูล Passive Buzzer ใช้ไฟเลี้ยง 3.3 - 5V สามารถสร้างเสียงคนตรีได้ (เหมาะทำเสียงกันขโมย) Description: Pressure of work: 3.3-5V holes for easy installation bolts fixed size PCB: 3.3 x 1.3 cm DuPont line length, 21 cm modules are used. drive transistor 9012 characteristics: no Origin vibrations require energy (frequency 2K-5K) to drive the control frequency, you can "do, re, mi fa sol la si" the definition of Pinter: /* VCC:. 5V-3.3V GND,: ground I /O :13 Test Ubo-r3 Code 1:เสียงเพลง */ int speakerPin = 13; int length = 15; // the number of notes char notes[] = "ccggaagffeeddc "; // a space represents a rest int beats[] = { 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 2, 4 }; int tempo = 300; void playTone(int tone, int duration) { for (long i = 0; i digitalWrite(speakerPin, LOW); delayMicroseconds(tone); digitalWrite(speakerPin, HIGH); delayMicroseconds(tone); } } void playNote(char note, int duration) { char names[] = { 'c', 'd', 'e', 'f', 'g', 'a', 'b', 'C' }; int tones[] = { 1915, 1700, 1519, 1432, 1275, 1136, 1014, 956 }; // play the tone corresponding to the note name for (int i = 0; i if (names[i] == note) { playTone(tones[i], duration); } } } Code 2:การแจ้งเตือน const int buzzer = 13; //buzzer to arduino pin 13 void setup(){ pinMode(buzzer, OUTPUT); // Set buzzer - pin 13 as an output } void loop(){ tone(buzzer, 600); // Send 600Hz sound signal... delay(500); // ...for 1/2 sec noTone(buzzer); // Stop sound... delay(500); // ...for 1/2 sec }
