Kule projekthi, siza kubonisa indlela yokwakhaimoto yokungcangcazelaisekethe.
AImoto yokudlidliza ye-dc 3.0vyimoto engcangcazelayo xa inikwe amandla aneleyo. Yimoto engcangcazelayo ngokoqobo. Ilungile kakhulu ekungcangcazeleni kwezinto. Ingasetyenziswa kwizixhobo ezininzi ngeenjongo ezisebenzayo. Umzekelo, enye yezona zinto zixhaphakileyo ezingcangcazelayo ziifowuni ezingcangcazelayo xa zibizwa xa zibekwe kwimo yokungcangcazela. Ifowuni ephathwayo ngumzekelo wesixhobo se-elektroniki esinemoto yokungcangcazela. Omnye umzekelo ungaba yipakethi yokugquma yomlawuli womdlalo ongcangcazelayo, ulinganisa izenzo zomdlalo. Isilawuli esinye apho ipakethi yokugquma inokongezwa njengesixhobo yi-nintendo 64, eza neepakethi zokugquma ukuze umlawuli angcangcazele ukuze alinganise izenzo zemidlalo. Umzekelo wesithathu ungaba yinto yokudlala efana ne-furby engcangcazelayo xa umsebenzisi esenza izenzo ezifana nokuyihlikihla okanye ukuyicinezela, njl.
Ngoko kei-dc mini magnet ingcangcazelaIisekethe zemoto zinezicelo eziluncedo nezisebenzisekayo ezinokusebenza ngeendlela ezininzi.
Ukwenza i-vibration motor idlidlize kulula kakhulu. Esimele sikwenze kukongeza i-voltage efunekayo kwii-terminals ezimbini. I-vibration motor inee-terminals ezimbini, ngesiqhelo i-wire ebomvu kunye ne-blue wire. I-polarity ayibalulekanga kwii-motors.
Kwimoto yethu yokungcangcazela, siza kusebenzisa imoto yokungcangcazela eyenziwe yiPrecision Microdrives. Le moto inoluhlu lwevolthi yokusebenza oluyi-2.5-3.8V oluza kusetyenziswa.
Ngoko ke ukuba sidibanisa ii-volts ezi-3 kwisiphelo sayo, iya kungcangcazela kakuhle, njengoko kubonisiwe ngezantsi:
Yiyo yonke into efunekayo ukuze injini yokungcangcazela ingcangcazele. Ii-volts ezi-3 zingabonelelwa ziibhetri ezimbini ze-AA ezilandelelanayo.
Nangona kunjalo, sifuna ukuthatha isekethe ye-vibration motor siye kwinqanaba eliphambili kwaye siyivumele ilawulwe yi-microcontroller efana ne-i-arduino.
Ngale ndlela, sinokuba nolawulo olunamandla ngakumbi kwi-vibration motor kwaye singayenza idlidlize ngamaxesha athile ukuba sifuna okanye kuphela xa kwenzeka isiganeko esithile.
Siza kubonisa indlela yokudibanisa le moto kunye ne-arduino ukuvelisa olu hlobo lolawulo.
Ngokukodwa, kule projekthi, siza kwakha isekethe size siyicwangcise ukuzeinjini engcangcazelayo yengqekembeI-12mm iyangcangcazela yonke iminithi.
Isekethe yemoto yokungcangcazela esiza kuyakha iboniswe ngezantsi:
Umzobo wesicwangciso sale sekethe ngulo:
Xa uqhuba imoto nge-microcontroller efana ne-arduino esinayo apha, kubalulekile ukuqhagamshela i-diode reverse biased in parallel nemoto. Oku kuyinyaniso xa uyiqhuba nge-motor controller okanye i-transistor. I-diode isebenza njengesikhuseli se-surge nxamnye ne-voltage spikes enokwenziwa yimoto. Ii-windings zemoto zivelisa ii-voltage spikes njengoko zijikeleza. Ngaphandle kwe-diode, ezi voltages zinokutshabalalisa ngokulula i-microcontroller yakho, okanye i-motor controller IC okanye zikhuphe i-transistor. Xa unika amandla i-vibration motor ngqo nge-DC voltage, akukho diode ifunekayo, yiyo loo nto kwi-simply circuit esinayo ngasentla, sisebenzisa kuphela umthombo we-voltage.
I-capacitor ye-0.1µF ifunxa ii-voltage spikes eziveliswa xa iibhrashi, ezizii-contacts ezidibanisa umbane kwii-motor windings, zivula kwaye zivala.
Isizathu sokuba sisebenzise i-transistor (i-2N2222) kukuba uninzi lwee-microcontrollers zineziphumo zamandla ezibuthathaka, oko kuthetha ukuba azikhuphi amandla aneleyo okuqhuba iintlobo ezahlukeneyo zezixhobo ze-elektroniki. Ukuze silungise le mveliso yamandla ibuthathaka, sisebenzisa i-transistor ukubonelela ngokwandiswa kwamandla angoku. Le yinjongo yale transistor ye-2N2222 esiyisebenzisayo apha. I-vibration motor ifuna malunga ne-75mA yamandla angoku ukuze iqhutywe. I-transistor ivumela oku kwaye sinokuqhubaInjini yohlobo lwengqekembe ye-3v 1027Ukuqinisekisa ukuba umsinga omninzi kakhulu awuphumi kwimveliso ye-transistor, sibeka i-1KΩ ngokulandelelana kunye nesiseko se-transistor. Oku kunciphisa umsinga ukuya kumlinganiselo ofanelekileyo ukuze umsinga omninzi ungawusebenzisi amandla.Imoto encinci engcangcazelayo eyi-8mmKhumbula ukuba ii-transistor zihlala zibonelela ngokuphindaphindwe kalikhulu kune-base current engena ngayo. Ukuba asiyibeki i-resistor kwisiseko okanye kwi-output, i-current eninzi kakhulu ingonakalisa i-motor. Ixabiso le-resistor ye-1KΩ alichanekanga. Naliphi na ixabiso lingasetyenziswa ukuya kuthi ga kwi-5KΩ okanye nangaphezulu.
Siqhagamshela i-output eza kuqhuba i-transistor kwi-collector ye-transistor. Le yi-motor kunye nazo zonke izinto ezifunekayo kunye nayo ukukhusela i-electronic circuitry.
