Peb tab tom ua kom muaj caj npab muaj zog uas tuaj yeem nqa qhov hnyav thiab txav nws. Cia peb pib nrog cov khoom txias no.

Kauj Ruam 1: Ua Tus Neeg Hlau

Txoj haujlwm no yog hais txog kev ua lub ntsej muag servo caj npab. Kuv tau siv 2 stepper motors thiab 2 servo motors ntawm no. Peb kuj tseem tuaj yeem siv servo hloov chaw steppers tab sis cov steppers muaj lub zog ruaj khov thiab meej dua. Lawv tseem tuaj yeem ua haujlwm hnyav dua uas yuav muaj txiaj ntsig ntawm no raws li kuv tau siv hlau tsis siv yas rau ntawm cov khoom. Qhov kev tswj hwm loj yog ua los ntawm kev siv arduino uno. Lub hwj huam tau muab los ntawm lub laptop ncaj qha. Tab sis peb tseem tuaj yeem muab 5V muab ncaj qha siv lub roj teeb.

Kauj Ruam 2: Txhua Yam Txog Steppers

Rau stepper peb xav tau cov tsav tsheb uln2003 lossis uln2004 thiab l293d raws li hom uas peb siv lawv. Rau hom unipolar, peb xav tau darlington array txhawm rau nthuav dav tam sim no thiab rau hom bipolar, peb xav tau h-choj tsav tsheb raws li peb xav tau muab ob lub zog xa khoom. Kuv tau siv cov steppers hauv ob hom bipolar thiab unipolar hauv txoj haujlwm no. Hom bipolar muab ntau lub zog thaum unipolar yog qhov tseeb dua thaum nws los txog rau qib loj. Raws li cov ntaub ntawv ntawm stepper lub cev muaj zog, peb tuaj yeem suav cov kauj ruam uas tau ua rau ib qho kev hloov pauv. Qhov iav piv thiab qib loj yuav muaj nyob ntawd.

Kauj Ruam 3: Txuas Qhov Chaw

Daim duab txuas yog muab hauv qab no. Kev saib xyuas yuav tsum tau ua rau hauv av txhua qhov kev sib txuas gnd nrog gnd ntawm arduino. Rau servo peb tuaj yeem ncaj qha muab 5V coj los ntawm pawg thawj coj saib arduino. Tab sis stepper rub ntau dua tam sim no. Yog li ntawd peb yuav tsum muab qhov sib cais tsis pub ntau tshaj 5V rau cov steppers yog qhov ntsuas yog 5V. Peb kuj tseem tuaj yeem tswj qhov ntsuas hluav taws xob siv qhov ntsuas hluav taws xob IC 7805. Xa cov duab los txuas cov khoom siv.

Kauj ruam 4: Arduino Code

Luam paste cov cai hauv arduino lub tswv yim. Yog tias koj tsis muaj cov tsev qiv ntawv suav nrog hauv txoj cai, thov rub tawm lawv ua ntej siv txoj cai. ntawm cov kauj ruam koj xav kom koj lub cav mus. Thawj tus stepper yog tus nyob hauv lub hauv paus thiab tus stepper2 yog tus uas tswj qhov siab ntawm servo motors. Tom ntej no, koj yuav tsum nkag mus rau lub kaum sab xis uas koj xav kom cov servos mus. Calibrate thiab teeb tsa lawv kom raug kom lawv mus rau hauv daim iav tsab ntawv tsa suab.

Kauj Ruam 5: Kauj Ruam Kawg

Txuas txhua yam kom ruaj ntseg siv cov hlua jumper thiab txuas lawv kom ruaj ntseg. Txhua koj qhov zoo tshaj plaws los sib npaug kev teeb tsa los ntawm kev qaij. Ntsia tus nqes mus rau tus ncej ntoo yuav ua haujlwm tau. Tom qab xa cov cai, koj tuaj yeem nqa qee yam khoom thiab tswj nws kom tso nws ntawm lwm qhov chaw. Koj tseem tuaj yeem ntxiv qhov no rau tus neeg hlau ntawm lub log thiab ua rau nws loj!
