Arduino Sensor Buzzer 5V jẹ ẹrọ itanna ti a lo lati mu awọn ohun orin dun ati awọn orin aladun ṣiṣẹ. O gba advantage ti awọn ero isise ká agbara lati gbe awọn PWM awọn ifihan agbara lati mu orin. Buzzer ti wa ni edidi sinu nọmba pin 9, eyiti o ṣe atilẹyin iṣẹ ṣiṣe ti kikọ ifihan agbara PWM si rẹ.

O ṣe pataki lati ṣe akiyesi pe awọn buzzers ni polarity. Awọn ẹrọ iṣowo ni igbagbogbo ni okun waya pupa ati dudu, ti n tọka bi o ṣe le pulọọgi sinu igbimọ naa.

Example 1: Play Melody

// Play Melody
// ----------
// Program to play a simple melody
//
// Tones are created by quickly pulsing a speaker on and off
// using PWM, to create signature frequencies.
//
// Each note has a frequency, created by varying the period of
// vibration, measured in microseconds. We'll use pulse-width
// modulation (PWM) to create that vibration.
//
// We calculate the pulse-width to be half the period; we pulse

Lati lo Arduino Sensor Buzzer 5V, tẹle awọn igbesẹ wọnyi:

So Arduino ọkọ 5V pin si awọn buzzer ká rere (+) ebute.
So Arduino ọkọ ká GND pin si awọn buzzer ká ilẹ (GND) ebute.

So Arduino ọkọ pin 9 si awọn buzzer ká ifihan agbara (S) ebute.

Ni kete ti awọn asopọ ti wa ni ṣe, o le po si awọn Mofi peseample koodu si Arduino ọkọ rẹ. Koodu yii yoo mu orin aladun rọrun kan nipa lilo iṣatunṣe iwọn pulse-iwọn (PWM) lati ṣẹda awọn ohun orin oriṣiriṣi.

Eyi example ṣe awọn lilo ti a buzzer ni ibere lati mu awọn orin aladun. A n gba advantage ti awọn ero isise agbara lati gbe awọn PWM awọn ifihan agbara ni ibere lati mu orin.
Buzzer kii ṣe nkankan bikoṣe ẹrọ itanna ti o lo lati mu awọn ohun orin ṣiṣẹ Ni iṣaaju waample a ti wa ni plugging awọn buzzer lori pin nọmba 9, ti o atilẹyin awọn iṣẹ-ti kikọ a PWM ifihan agbara si o, ki o si ko o kan itele ga tabi kekere iye.

Ni igba akọkọ ti example ti koodu yoo kan firanṣẹ igbi onigun mẹrin si buzzer, lakoko ti ọkan yoo lo iṣẹ ṣiṣe PWM lati ṣakoso iwọn didun nipasẹ yiyipada Iwọn Pulse.
Ohun miiran lati ranti ni pe awọn buzzers ni polarity, awọn ẹrọ iṣowo nigbagbogbo ni pupa ati awọn okun onirin dudu ti n tọka bi o ṣe le pulọọgi si igbimọ naa.
