Buzzer: zvese nezve mudziyo uyu kuburitsa ruzha

Gadzira beep Icho chinhu chinotsvakwa muzvirongwa zvakasiyana zve DIY, ndosaka vagadziri vachifanira kushandisa akasiyana madhijitari kuburitsa ruzha rwacho. Imwe yemidziyo iwe yaunogona kushandisa ndeye diki mutauri, kunyange hazvo isiri iyo inonyanya kukodzera kana chinhu chega chaunotumira chiri chiratidzo chemagetsi, nekuti icho chinogadzira kupesana kwehunhu kana kubaya nekuda kwekuzungunuka kwemembure, asi ruzha rudiki. Naizvozvo, zvakanakisa kushandisa buzzer kana buzzer.

Iyo saizi inowanzo kuve diki zvakanyanya pane zvakajairwa maspika, uye chii chiri nani, iyo bhaza inogadzira beep kana kurira izvo zvinokwezva kutarisisa kupfuura iro ruzha kubva kumutauri kana pasina chiratidzo cheodhiyo chakapihwa kwairi. Saka kana iwe uri mugadziri uye uchida kuburitsa chero chenjedzo yechiitiko muchirongwa chako, chishandiso chatinokupa nhasi chichaenderana newe segirovhosi ...

Chii chinonzi buzzer kana buzzer?

Buzzer kana buzzer chishandiso chemagetsi chinoita se transducer. Basa rayo kuburitsa yakakwira-inodzika kana kurira kurira apo simba riri kupihwa kwariri. Ndosaka zvakakosha kusangana neArduino, nekuti kana chiitiko chikagadzirwa chaunoda kuyambira kana kunyevera, unogona kuronga microcontroller kuti itumire chiratidzo kune buzzer kana chiitiko ichocho chikaitika uye nekukuyambira nezwi irori.

kubudikidza ejemploKana iwe wakamboshandisa sensor tembiricha uye iwe uchida kuti ikuyambire iwe kana ichipfuura 100 youC, ipapo unogona kushandisa buzzer sechinhu chekuzivisa uye iyo Arduino inotumira chiratidzo chemagetsi kune iyo buzzer apo iyo tembiricha sensor inoita izvo zviyero. Zviripachena, iko kunyorera kwaunowana kwakasiyana kwazvo ...

Mumba mako, mune michina yakawanda uko iwe unogona kuwana buzzers, semuenzaniso mumaawa e alarm. Mazhinji emawachi aya anoshandisa mabuzzers kuburitsa ruzha, kunyanya iwo madiki, kunyangwe vamwe vangashandisa maspika kukumutsa neredhiyo, nerwiyo, nezvimwe. Ichokwadi ndechekuti haufanire kubvarura chero chinhu ku tora buzzerMuchokwadi zvakachipa kwazvo uye zviri nyore kuwana.

Mhando dzebuzzers

Unogona kuwana mhando dzakasiyana, Kunze kweavo vanoshandisa magetsi emagetsi kana piezoelectric disc iwe unogona zvakare kuwana:

• Avo avo usabatanidze oscillator: mune ino kesi oscillator yekunze inodikanwa kuti ishande zvakanaka.
• Avo avo revatema oscillator- Iyo yakavakirwa-mukati oscillator inoita kuti zvive nyore kushanda, ingoisa iyo voltage kune zviteshi zveye buzzer kana buzzer uye iwe unenge uine ruzha.

Zvakakosha kuyeuka izvo futi kune akakosha mamamojuru eArduino neBuzzer uye zvese zvaunoda kuti zvive nyore kubatana neako aunofarira DIY bhodhi.

Operation

Bumbiro rayo rakareruka, rinongova naro chete electromagnet kana piezoelectric disc (zvinoenderana nerudzi rwebhaza) uye nesimbi sheet. Izvi zvinokwana kuti ibudise ruzha kana yazvino ichiendeswa kune piezoelectric kana electromagnet uye izvi zvinoita kuti simbi foil izununguke.

Iyo inowanzozivikanwa ndeyeiyo piezoelectric mhando, mune iyi kesi vane simbi jira rakanamirwa kune zvedongo jira. Kana yaiswa kunetsana pakati pemaberere maviri achiburitsa bhatani. Kana iwo magetsi aunopihwa akamira, vanodzokera kune yavo yakajairika mamiriro. Asi kana wachi kana imwe pulses ikagadzirwa, inoburitsa mabheepu anonzwika atiri kutsvaga.

Kubatanidzwa naArduino

Su kusangana pamwe neArduino Izvo hazvigone kuve nyore, kunyangwe iwe ukatenga yakajairwa buzzer kana passive module yeArduino inogona kusunganidzwa zviri nyore kwazvo uye iyo kodhi iyo iwe yaunofanirwa kunyora muArduino IDE iri nyore zvakare futi (iyo base, ipapo zvinoenderana neicho unoda kuwedzera).

Kana iri a yakapusa kodhi muenzaniso, inogona kunge iri inotevera, mune iyo buzzer inoburitsa ruzha rwe1 sekondi uye inomira, inodzoka kugadzira 1 sekondi, uye seizvi:

/* Programa simple para emitir pitidos de 1 segundo intermitentes */

const int buzzer = 9; //El pin al que se conecta el buzzer es el 9

void setup(){

  pinMode(buzzer, OUTPUT); // Pin 9 declarado como salida

}

void loop(){

  tone(buzzer, 50); // Envía señal de 1Khz al zumbador
  delay(1000);
  noTone(buzzer);     // Detiene el zumbador
  delay(1000);        //Espera un segundo y vuelve a repetir el bucle

}
