Yaba imbeba ntoya ya robot cyangwa umuyaga muto w'amashanyarazi IoT, uzi kugenzura ibintu hamwe na moteri ya DC hamwe naimashini y'ibikoreshoifungura imishinga myinshi yo guhanga DIY kugirango ukomeze guhugira.Muriyi nyigisho, dukoresha ila38umugenzuzi wa moteri kuri aimashini y'ibikoreshoKuri power no kuzunguruka moteri ya DC!
Uwitekala38Module Igenzura Module ninama ifasha microcontrollers na microprocessors nkaimashini y'ibikoreshomoteri ya DC isaba ibirenga 3.3V cyangwa 5V.
Ikoreshala38IC kugirango yongere imbaraga zose zo gucunga no gukenera imbaraga zikenewe kugirango utangire moteri no gutandukanya theimashini y'ibikoreshouhereye kuri voltage ndende ikoreshwa kuri moteri ya DC.
Uwitekala38module nigikoresho nyamukuru kigenzura moteri mugitangira robotics kit kuko byoroshye gukoresha.Ifite imitwe ya pin aho ushobora gushyiramo abasimbuka kugirango uyihuze nezaimashini y'ibikoresho.Urashobora kandi kwihuta cyangwa gutinda moteri ukoresheje pulse-ubugari bwa modulasiyo (PWM) kubimenyetso byayoterminal.
Kubirebaikigezwehos, ila38ni amuremure ikigezweho.Mu byukuri ni a10 amp ikigezwehos bigizwe na moteri hamwe na bineamashanyarazi y'akanya gato kuvugana.Ibi biragufasha gushiraho icyerekezo kigezweho utongeye guhuza moteri.Guhindura icyerekezo cyubu kuri H-ikiraro nacyo gihindura icyerekezo cyo kuzenguruka moteri.La38 ifite uburyo bubiri bwo guhuza nabo, igufasha kugenzura moteri yigenga.Niba uri mushya kuri gahunda ya Python, ntucikwe nibi bifasha Python imwe-imwe.
Mugihe mugihe cyizunguruka, ibumosoIburyo na Iburyo Imbere ibanza gufungura isegonda imwe.Kugenzura umuvuduko, hindura ibicuruzwa bisohoka byinshingano.Banza ubashyire kumurongo 100% kumasegonda imwe, hanyuma ubishyire kuri 50%.Inshingano yumusoro wa 100% izakoresha moteri kumuvuduko ntarengwa, mugihe icyiciro cya 50% kizakora kumuvuduko wa kabiri.
Uzigame nka "rpi-dcmotor.py" cyangwa irindi zina rya fayili niba rirangiye no kwagura ".py".Nyuma yibyo uzimye ibyaweimashini y'ibikoresho.
ICYITONDERWA.Utwo dusimba dusimbuka duhita uhuza EN pin na 5V, “ukwemerera” kugenzuraikigezwehoBinyuze muri IN pin.Mugihe ugomba kuba utanga ingufu ukoresheje iyi pin, 5V irashobora gutera ibibazo bimwe na bimweimashini y'ibikoreshonkuko biteganijwe gukoresha 3.3V aho gukoresha 5V.Na none, guhuza iyi pin kuriimashini y'ibikoreshobizagufasha kugenzura umuvuduko wa moteri nyuma..
Inama: Kugirango umenye umubare wa pin uri kuriweimashini y'ibikoresho, komeza kugirango pin ya GPIO iri iburyo.Ibi ni uduce duto twicyuma twicaye kumurongo wumukara.Noneho, iyo urebye hejuru yibumoso hejuru uhereye kuri tray, iyo ni pin 1. Iburyo bwibyo ni pin 2. Munsi ya pin 1 ni pin 3, nibindi.
ICYITONDERWA.Moteri nyinshi za DC ntabwo zifite insinga zo kugurisha.Urashobora kubigurisha wenyine.Igipimo icyo aricyo cyose kizakora, ariko insinga z'umuringa zahagaritswe zikora neza.
Urashobora gukoresha kode ukoresheje inyandiko kuri terminal.Ariko mbere yibyo, ugomba kongeramo imbaraga kurila38module.
Uwitekala38Moderi ya DC Igenzura Module irashobora guhuzwa numuyoboro wose wa DC mugihe cyose amashanyarazi atarenze 45V.Kubijyanye no gukoreshwa, byoroshe gukoresha bateri 9V hamwe nicyuma cya DC gihujwe nimbaraga za module.
Ntugomba kandi guhangayikishwa na bateri 9V yangizaimashini y'ibikoresho.Uwitekala38module ikoresha IC idasanzwe yitwa MOSFET ikora nkimbaraga nkeya, ihinduka anamashanyarazi y'akanya gatohindura itandukanya pin yawe kumashanyarazi.
Nigute nshobora kohereza amashanyarazi kuva kuri pin kugirango nkore moteri ya DC?Reka dusuzume neza uburyo dukora moteri izunguruka.
Uwitekala38moteri igenzura moteri ikoresha byinshiamashanyarazi y'akanya gatoihindura kugirango igenzure kuzenguruka kwa moteri.Urashobora gutekereza kuri swatike nkurukuta, usibye ko badakoresha intoki zawe gukora - bakoresha 3.3V uhereye kuriimashini y'ibikoresho.
Kandi aho niho GPIO.ibisohoka (, GPIO.HIGH).Iyi ni GPIO.ibisohoka (, GPIO.HIGH).Gushira iyi pin kuri GPIO.HIGH itera iyi pin gusohora 3.3V.Ibiikora, kwemerera umuyaga gutembera kuri moteri.Umuyoboro noneho uzunguruka moteri.Kuramo iyi pin kuri GPIO.LOW izimya switch, igabanya ingufu kuri moteri.
Turashobora guhindura icyerekezo cyo kuzenguruka moteri duhindura icyerekezo cyumuyaga binyuze muri moteri.Niyo mpamvu dufite amapine abiri atandukanye kugirango tugenzure kuzenguruka moteri imwe: inyuma n'imbere.Barakoraamashanyarazi y'akanya gatoihinduranya kumpande zombi zitanga amashanyarazi, ikayobora ingufu imbere cyangwa inyuma.
Ni nako bigenda ku muvuduko.Bitandukanye nibisohoka byimbere nibisubiza inyuma, gushoboza pin igenzura ingano yingufu zinyura muri moteri mugihe runaka.
Mugukomeza voltage kuri enter-on contact, switch zabo zifungura "mugari" nkeya kandi zemerera amashanyarazi menshi kunyura muri moteri.Kongera imbaraga za moteri bituma bazunguruka vuba.Kugabanuka bituma batinda.
Kuriimashini y'ibikoresho, dukoresha PWM cyangwa Pulse Modulation kugirango tugenzure ibisohoka voltage ya pin.Kongera umusoro winshingano bizana voltage ntarengwa hafi ya 3.3V, no kuyigabanya hafi ya 0V.
Nkako, urashobora “Zimya”Moteri muburyo bumwe mugushiraho moteri ituma pin kuri 0V.Bitekerezeho nkikintu kimeze nkimodoka: ibipapuro bishoboza gutanga gaze itanga moteri, kandi imigozi yimbere ninyuma ihinduranya ibyuma, ibemerera kugenda imbere cyangwa inyuma.
Ziratandukanye bitewe na colenoid zabo ziri.Moteri ya DC yasunitswe ifite coil hagati izunguruka hagati yimpeta ya magnesi zihoraho.Moteri ya DC idafite amashanyarazi ifite coil kurundi ruhande - amashanyarazi ya electroniki ya magnetiki azenguruka magnesi zihoraho.
Moteri yo gukusanya irahendutse kandi ifite imikorere myiza kumuvuduko muke.Nyamara, bakunda gushyuha byihuse kuruta moteri idafite amashanyarazi kandi ntibikoresha ingufu nke.Kurundi ruhande, moteri idafite amashanyarazi irashobora kugera ku muvuduko mwinshi, gushyuha cyane, no gukoresha imbaraga nke kugirango izunguruke vuba kuruta moteri yasunitswe.
Niba ukoresha moteri imbere aimashini y'ibikoreshorobot ya garebox, moteri yasunitswe igomba kuba nziza.Ariko, niba ukoresha moteri idafite moteri nkumuyaga muto wamashanyarazi, moteri idafite amashanyarazi igomba kuba nziza.
Nubwo ibi bishobora gutandukana nuwabikoze, urashobora kwitega 2A impinga ya moteri kuri moteri murila38moteri ya moteri.
Terence numukunzi wa robo ugerageza kubaka robot nziza kwisi.Niba atari gutwika LED nk'icyifuzo cya kabiri, yari kubyakira kera cyane.
Kumenyekanisha.Gukora byoroshye kubona komisiyo kubicuruzwa byaguzwe binyuze mumihuza yacu ishyigikira umurimo dukorera abasomyi bacu.
