ARDUINO Sensor Buzzer 5V Module

Arduino Sensor Buzzer 5V Buku Logwiritsa Ntchito

Arduino Sensor Buzzer 5V ndi chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kusewera ma toni ndi nyimbo. Zimatengera advantage za kuthekera kwa purosesa kupanga ma sign a PWM kuti aziimba nyimbo. Buzzer imalumikizidwa mu pini nambala 9, yomwe imathandizira ntchito yolembera chizindikiro cha PWM kwa iyo.

Ndikofunika kuzindikira kuti ma buzzers ali ndi polarity. Zipangizo zamalonda nthawi zambiri zimakhala ndi waya wofiyira ndi wakuda, zomwe zikuwonetsa momwe zingalumikize pa bolodi.

// 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

Kuti mugwiritse ntchito Arduino Sensor Buzzer 5V, tsatirani izi:

1. Lumikizani pini ya 5V ya board ya Arduino ku terminal ya buzzer's positive (+).
2. Lumikizani pini ya GND ya board ya Arduino kutheshoni ya buzzer's ground (GND).
3. Lumikizani pini 9 ya board ya Arduino ku terminal ya buzzer's sign (S).

Malumikizidwewo akapangidwa, mutha kukweza zomwe zaperekedwa kaleamplembani ku board yanu ya Arduino. Khodi iyi idzayimba nyimbo yosavuta kugwiritsa ntchito pulse-width modulation (PWM) kupanga ma toni osiyanasiyana.

• Ex iziampLe amagwiritsa ntchito buzzer kuti aziyimba nyimbo. Tikutenga advantage za mapurosesa omwe amatha kupanga ma sign a PWM kuti azisewera nyimbo.
• Buzzer si kanthu koma chipangizo chamagetsi chomwe chimagwiritsidwa ntchito kusewera ma toni Mu ex yathuample tikulumikiza buzzer pa pini nambala 9, yomwe imathandizira ntchito yolembera chizindikiro cha PWM kwa iyo, osati chabe mtengo wa HIGH kapena LOW.
• Woyamba example la code lidzangotumiza mawonekedwe a square ku buzzer, pamene yachiwiri idzagwiritsa ntchito ntchito ya PWM kuwongolera voliyumu mwa kusintha Pulse Width.
• Chinthu china choyenera kukumbukira ndi chakuti ma buzzers ali ndi polarity, zipangizo zamalonda nthawi zambiri zimakhala ndi mawaya ofiira ndi akuda omwe amasonyeza momwe angagwiritsire ntchito bolodi.
