Nyob zoo txhua tus, vam tias koj muaj hnub zoo. Yog tias tsis cia siab koj tuaj yeem rov qab nrog qee qhov qhib siab rau qhov kev qhia no thiab qee cov suab paj nruag kho. Programming tuaj yeem ua teeb meem. Ua tsaug, qhov kev qhia no tsis yog qhov nyuaj, yog li koj tuaj yeem muaj peev xwm ua tiav qhov nrov npe hu ua (hauv lub suab muaj zog): LUB KAWG KAWG KEYPAD XAUS KAWG !!! Qhov ntawd tsuas yog kuv qhov kev qhia, vam tias koj nyiam nws. Xijpeem, cia peb ua kom peb cov ntiv tes sov rau kev ntaus ntawv. (Ib zaj nkauj txias: tuaj yeem-tuaj yeem hu nkauj (suab paj nruag qub)).

Khoom siv:

Koj cov ntiv tes

-Koj txhais tes ib yam nkaus, qhov tseem ceeb

-USB cable rau Arduino

Txhua hom arduino muaj (Kuv muaj Arduino Mega)

-Matrix Keypad (keyboard - ebay, keypad - amazon)

-Micro lossis Standard servo (Kuv siv micro servo)

-* Yeem tau* Breadboard - txhua yam

-* Yeem* Fais fab mov (5V)

Kauj ruam 1: Sijhawm Schematic

Yog li, ua ntej dab tsi? Txuas tus Arduino mus rau lub khoos phis tawj. Txuas tus keypad tom ntej. *Nco tseg - koj yuav tsum txuas tus pin los ntawm tus lej kawg ntawm tus keyboard yog thawj tus lej digital ntawm arduino. Thiab mus ntawm sab xis mus rau sab laug tom qab ntawd*. Keypad muaj tus pin 2-9 ntawm arduino. Lub servo muaj tus pin 10 ua cov cim digital. Tie thaj tsam ntawm arduino, keypad, thiab servo thiab 5V ib yam nkaus. * Tseem ceeb - qhov kev pabcuam zoo tshaj plaws nrog lub zog siv sab nraud lossis lub adapter nrog 5V (phab ntsa ntsaws -hauv), tab sis nws tseem xaiv tau.* Koj tsis tas yuav khi thaj chaw thiab 5V lub cev, kuv txhais li cas yog kom tsuas yog txuas cov xov hlau los ntawm Arduino mus rau servo. Cov txheej txheem no tsis pab pib, yog li cia kuv piav qhia luv luv. Yeej, tus pin kawg yog 2 thiab thawj tus yog 9, ob yog 8, peb yog 7, thiab ntxiv rau. Mus ntawm sab laug mus rau sab xis 22.

Kauj ruam 2: Coding Sijhawm

Yog li tam sim no peb tab tom mus rau ntu coding! Nov yog qhov uas khawv koob tiag tshwm sim! Yog li, muaj qhov kev tshuaj ntsuam xyuas thawj zaug los ntsuas cov keyboard thiab servo. Ntawm no:

Kauj Ruam 3: Txhua Qhov No Puas Yog?

Cov cai saum toj no (thawj tus) yuav muab lub teeb liab rau Servo kom "cheb" lossis tsuas yog mus ntawm 0 txog 180 degrees. Lossis tsuas yog ua kom tiav ib nrab ntawm lub voj voog ntawm kev sab laug mus rau sab xis lossis sab xis mus rau sab laug. Yog tias koj xav paub ntau ntxiv ntawm tus lej kuv tuaj yeem qhia koj. Tsuas yog thov nug. Tsis muaj kev phom sij ua tiav, tsuas yog lo lus nug me me yooj yim. Los, koj ua tau! Xijpeem, txoj cai nyob hauv nruab nrab ntsuas txhua lub pob ntawm cov keyboard. Thiab qhov kawg ntawm txoj cai tsuas yog "xauv" nrog lub servo thaum koj ntaus tus lej "1234" rau hauv, koj kwv yees nws, cov keyboard.

Kauj ruam 4: Troubleshooting

Q: Kuv lub keyboard tsis ua haujlwm.

A: Nco ntsoov thawj tus pin yog 9 yog li nqis los ntawm qhov ntawd. Tsis tas li nco ntsoov txuas lub arduino mus rau USB chaw nres nkoj ntawm lub computer thiab program Arduino.

Q: Servo tsis ua haujlwm.

A: Nco ntsoov tias tus pin servo yog tus pin 10 thiab koj xav tau ib qho hauv av, yog tias koj txuas ncaj qha los ntawm Arduino, nco ntsoov tias tus txiv kab ntxwv tus pin (ntawm micro servo) yog tus pin 10, tus pin liab yog 5V, thiab tus pin xim av yog GND tus pin.

Q: Arduino tsis ua haujlwm:

A: Koj puas tau txuas nws? Qhov ntawd zoo li yog teeb meem ntawm tus kheej

Kauj Ruam 5: Yog tias Koj Muaj Lus Nug, Ua Ntej Xav Nug Hauv Kab Lus Tawm thiab Nco ntsoov Sau Npe

Bye, ua tsaug rau kev saib kuv cov lus qhia. Nws tau lom zem.
