ARDUINO Sensor Buzzer 5V Module
Arduino Sensor Buzzer 5V Bukana ea Mosebelisi
Arduino Sensor Buzzer 5V ke sesebelisoa sa elektroniki se sebelisetsoang ho bapala melumo le meloli. E hloka peletage ea bokhoni ba processor ea ho hlahisa matšoao a PWM ho bapala mmino. Buzzer e hoketsoe ho pin nomoro ea 9, e ts'ehetsang ts'ebetso ea ho ngola lets'oao la PWM ho eona.
Ke habohlokoa ho hlokomela hore li-buzzers li na le polarity. Lisebelisoa tsa khoebo hangata li na le terata e khubelu le e ntšo, e bontšang mokhoa oa ho e kenya ka har'a boto.

ExampLe 1: Bapala 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
Ho sebelisa Arduino Sensor Buzzer 5V, latela mehato ena:
- Hokela phini ea 5V ea Arduino board ho theminale ea buzzer positive (+).
- Hokela phini ea GND ea boto ea Arduino ho theminale ea buzzer's ground (GND).
- Hokela phini ea 9 ea boto ea Arduino ho theminale ea lets'oao la buzzer (S).
Hang ha lihokelo li entsoe, u ka kenya ex e fanoengample khoutu ho boto ea hau ea Arduino. Khoutu ena e tla bapala molodi o bonolo o sebedisa pulse-width modulation (PWM) ho etsa medumo e fapaneng.
Bapala Melody
- Example etsa tshebediso ya buzzer bakeng sa ho bapala melodi. Re nka advantage ea bokhoni ba processors ho hlahisa matšoao a PWM molemong oa ho bapala mmino.
- Buzzer ha se letho haese sesebelisoa sa elektroniki se sebelisetsoang ho bapala lithane tsa rona tsa khaleample re ntse re kenya buzzer ho nomoro ea pin 9, e tšehetsang mosebetsi oa ho ngola letšoao la PWM ho eona, eseng feela boleng ba HIGH kapa LOW.
- Example ea khoutu e tla romela leqhubu la lisekoere ho buzzer, ha ea bobeli e tla sebelisa ts'ebetso ea PWM ho laola molumo ka ho fetola Pulse Width.
- Ntho e 'ngoe eo u lokelang ho e hopola ke hore li-buzzers li na le polarity, lisebelisoa tsa khoebo hangata li na le lithapo tse khubelu le tse ntšo tse bontšang mokhoa oa ho li kenya ka har'a boto.

- Melumo e etsoa ka ho phunya sebuela kapele le ho se tima
- ho sebelisa PWM, ho theha maqhubu a ho saena.
- Noto e 'ngoe le e 'ngoe e na le makhetlo a mangata, e entsoeng ka ho fapana ha nako ea
- thothomelo, e lekantsoeng ka microseconds. Re tla sebelisa pulse-width
- modulation (PWM) ho theha thothomelo eo.
- Re bala pulse-width ho ba halofo ea nako; re otla * sebui se HIGH bakeng sa "pulse-width" microseconds, ebe LOW
- bakeng sa li-microseconds tsa 'pulse-width'.
