Kule phrojekthi, sizobonisa indlela yokwakha avibration motorisifunda.
Adc 3.0v vibrator motoriyinjini edlidliza lapho inikezwa amandla anele. Kuyimoto enyakaza ngokoqobo. Kuhle kakhulu ezintweni ezidlidlizayo. Ingasetshenziswa kumishini eminingi ngezinjongo ezingokoqobo. Isibonelo, enye yezinto ezivame kakhulu ezidlidlizayo amaselula adlidlizayo lapho ebizwa lapho ebekwe kwimodi yokudlidliza. Umakhalekhukhwini uyisibonelo esinjalo sedivaysi kagesi equkethe injini yokudlidliza. Esinye isibonelo singaba iphakethe elidumayo lesilawuli segeyimu esinyakazayo, silingisa izenzo zegeyimu. Isilawuli esisodwa lapho iphakethe le-rumble lingengezwa khona njengesisetshenziswa yi-Nintendo 64, efike namaphekhi e-rumble ukuze isilawuli sidlidlize ukuze silingise izenzo zegeyimu. Isibonelo sesithathu kungaba ithoyizi elifana ne-furby elidlidlizayo uma umsebenzisi enza izenzo ezinjengokulihlikihla noma ukulikhama, njll.
Ngakhodc mini kazibuthe vibratingama-motor circuits anezinhlelo zokusebenza eziwusizo kakhulu nezisebenzayo ezingasebenzisa izinkulungwane zemisebenzi.
Ukwenza i-vibration motor vibrate kulula kakhulu. Okufanele sikwenze nje ukwengeza i-voltage edingekayo kumatheminali ama-2. Injini yokudlidliza inamatheminali angu-2, ngokuvamile intambo ebomvu kanye nentambo eluhlaza okwesibhakabhaka. I-polarity ayinandaba nezinjini.
Ngenjini yethu yokudlidliza, sizobe sisebenzisa injini yokudlidliza nge-Precision Microdrives. Le moto inobubanzi be-voltage yokusebenza engu-2.5-3.8V okufanele inikwe amandla.
Ngakho-ke uma sixhuma ama-volts angu-3 kutheminali yayo, izodlidliza kahle, njengoba kukhonjisiwe ngezansi:
Yilokhu kuphela okudingekayo ukwenza i-vibration motor idlidlize. Ama-volts angu-3 anganikezwa amabhethri angu-2 AA ochungechungeni.
Kodwa-ke, sifuna ukuyisa isekethe yemoto yokudlidliza iye ezingeni eliphezulu kakhulu futhi siyivumele ilawulwe isilawuli esincane esifana ne-arduino.
Ngale ndlela, singaba nokulawula okunamandla ngaphezulu kwenjini yokudlidliza futhi singayenza idlidlize ngezikhathi ezimisiwe uma sifuna noma kuphela uma kwenzeka umcimbi othile.
Sizobonisa indlela yokuhlanganisa le motor ne-arduino ukukhiqiza lolu hlobo lokulawula.
Ngokuqondile, kule phrojekthi, sizokwakha isifunda futhi siyihlele ukuzeuhlamvu lwemali motor vibrating12mm idlidliza njalo ngeminithi.
Isekhethi ye-vibration motor esizoyakha iboniswe ngezansi:
Umdwebo wohlelo lwale sekethi uthi:
Uma ushayela injini ene-microcontroller efana ne-arduino esinayo lapha, kubalulekile ukuxhuma i-diode reverse echemile ngokuhambisana nenjini. Lokhu kuyiqiniso futhi uma uyishayela ngesilawuli se-motor noma i-transistor. I-diode isebenza njengesivikelo sokuhlinza ngokumelene nama-voltage spikes angenziwa injini. Amajika enjini adume kabi akhiqiza ama-voltage spikes njengoba izungeza. Ngaphandle kwe-diode, lawa ma-voltage angacekela phansi i-microcontroller yakho, noma isilawuli se-motor IC noma akhiphe i-transistor. Lapho nje unika amandla injini yokudlidliza ngokuqondile nge-voltage ye-DC, akukho diode edingekayo, yingakho kusekethe nje esinawo ngenhla, sisebenzisa umthombo we-voltage kuphela.
I-capacitor engu-0.1µF imunca ama-voltage spikes akhiqizwa lapho amabhulashi, okuyizinto ezixhumene nogesi oxhunywe kuma-motor windings, evuleka futhi evala.
Isizathu sokuthi sisebenzise i-transistor (a 2N2222) ingoba izilawuli ezincane eziningi zinemiphumela yamanje ebuthakathaka uma kuqhathaniswa, okusho ukuthi azikhiphi okwamanje ngokwanele ukushayela izinhlobo eziningi zemishini kagesi. Ukuze senze lokhu okukhiphayo kwamanje okubuthakathaka, sisebenzisa i-transistor ukuze sinikeze ukukhulisa kwamanje. Lena inhloso yale 2N2222 transistor esiyisebenzisa lapha. Injini yokudlidliza idinga cishe u-75mA wamanje ukuze ishayelwe. I-transistor ivumela lokhu futhi singakwazi ukushayela3v uhlamvu lwemali uhlobo motor 1027. Ukuqinisekisa ukuthi umthamo omningi kakhulu awuhambi usuka ekuphumeni kwe-transistor, sibeka i-1KΩ ochungechungeni nesisekelo se-transistor. Lokhu kwenza inani lamanje libe inani eliphusile ukuze amandla amanje amaningi angayiniki amandla8mm mini vibrating motor. Khumbula ukuthi ama-transistors ngokuvamile ahlinzeka cishe izikhathi eziyi-100 zokukhulisa isisekelo samanje esingena ngaso. Uma singabeki isixhasi esisekelweni noma ekuphumeni, umthamo wamanje omningi ungalimaza injini. Inani le-resistor engu-1KΩ alinembile. Noma yiliphi inani lingasetshenziswa kufika ku-5KΩ noma kanjalo.
Sixhuma okukhiphayo ukuthi i-transistor izoshayela kumqoqi we-transistor. Lena injini kanye nazo zonke izingxenye ezidingayo ngokuhambisana nayo ukuze kuvikelwe i-electronic circuitry.
