2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:31

Cov laug cam no hloov ib qho (HD44780-tau tshaj) LCD rau hauv cov lej LCD. Cov khoom siv muaj los ntawm moderndevice.com thiab tso cai rau LCD los tswj los ntawm arduino lossis clone nrog tsuas yog 3 xaim.

Kauj ruam 1: Tiv thaiv

Mount 10K resistor. Cov xim xim yog Xim av Txiv Kab ntxwv Dub.

Kauj Ruam 2: Tiv Thaiv Qee Qhov Ntxiv …

Mount 330 Ohm resistor. Cov xim yog Txiv kab ntxwv Txiv kab ntxwv Xim av.

Kauj Ruam 3: Tsuas Yog Ib Qhov Taw Qhia

Lub diode tsuas tuaj yeem ua haujlwm yog tias muab tso kom raug. Sib phim cov qhab nyiaj ntawm daim diode nrog cov qhab nias ntawm lub rooj tsavxwm.

Kauj Ruam 4: Capacitor

Mount lub monolithic capacitor. Kev taw qhia tsis muaj teeb meem.

Kauj ruam 5: Hloov

Mount cov keyboards. Cov no yuav ntsaws rau hauv pawg thawj coj hauv qhov qhia kom raug. Yog tias lawv zoo li tsis haum, tig 90 degrees thiab sim dua.

Kauj Ruam 6: Trimpot

Mount nce mus nce los resistor. Nov yog qhov uas koj yuav kho qhov sib txawv ntawm cov ntawv nyeem.

Kauj Ruam 7: Tus Tswj Fais Fab

Teem lub TSWV YIM 120. Kuv pom nws yooj yim heev rau khoov cov coj 90 degrees thiab tom qab ntawd muab tshuaj txhuam. Xyuas kom tseeb tias lub dab dej kub (hlau) ib feem ntawm lub rooj tsavxwm.

Kauj Ruam 8: Socket rau Kuv

Lub qhov (socket) IC yuav tsum tau teeb tsa nrog lub thais rau ntawm qhov sib txawv resistor. Solder hauv ob tus pin ntawm cov ces kaum sib txawv thiab tom qab ntawd txheeb xyuas qhov chaw. Ua kom tiav qhov muag thaum txhua yam nyob qhov twg nws yuav tsum yog.

Kauj Ruam 9: Dab Tsi Ntxiv?

Tam sim no koj yuav tsum txiav txim siab qhov twg lub teeb pom kev tiv thaiv xav tau rau cov zaub koj muaj. Yog tias koj muaj ib qho ntawm cov lus qhia los ntawm moderndevice.com qhov no yooj yim zoo nkauj. Yog tias koj muaj cov zaub sib txawv, saib ntawm no txhawm rau txiav txim siab tus nqi tiv thaiv xav tau. Rau qhov 2x16 Blue zaub, siv 28 Ohm resistor (Liab Grey Dub). Rau qhov 4x20 Blue zaub, siv 33 Ohm resistor (Txiv kab ntxwv Txiv kab ntxwv Dub) tus tiv thaiv no hauv qhov chaw cim Rbl.

Kauj ruam 10: Headers

Solder hauv lub taub hau uas yuav phim koj cov zaub. 2x16 thiab 4x20 cov lus qhia Kuv muaj ob qho tib leeg siv ib kab ntawm kab ntawv taub hau nyob rau sab saum toj ntawm pawg thawj coj saib. Ib kab ob kab ntawm lub taub hau tuaj yeem txuas rau sab xis ntawm lub rooj tsavxwm yog tias xav tau. Cov neeg muag khoom hauv cov pins ntawm txhua qhov kawg thiab tom qab ntawd txheeb xyuas qhov ua kom sib haum ua ntej yuav siv cov pins uas seem.

Kauj Ruam 11: Ntau Lub Taub Hau

Cov no yog cov headers uas mus rau arduino. Cov laug hauv 90 degree txiv neej lub taub hau muab.

Kauj Ruam 12: Yooj Yim Yooj Yim

Yog tias koj npaj yuav txhawb lub zog ntawm cov khoom siv ntawm arduino, raws li cov neeg feem coob yuav, koj yuav tsum tso lub jumper raws li qhia hauv daim duab hauv qab no. Qhov no hloov pauv lub zog pub los ntawm Vbl tus pin rau 5v tus pin. Kuv tsuas yog siv cov hlau txiav ua cov jumper los ntawm lub qhov mus rau cov hlau lead tiv thaiv.

Kauj Ruam 13: IC

Muab cov nti tso rau hauv lub qhov (socket) nrog lub thais rau ntawm qhov sib txawv resistor. Koj yuav zoo li yuav tsum tau ua tib zoo khoov cov coj kom nws haum lub qhov (socket).

Kauj Ruam 14: Cov Zaub, Cov phooj ywg

Yog tias koj cov zaub tseem tsis tau teeb tsa lub taub hau teeb tsa, tam sim no yog lub sijhawm zoo los tso rau hauv.

Kauj Ruam 15: Plug Rau Hauv

Txuas koj lub rooj tsavxwm rau hauv cov zaub thiab, siv cov hlua txuas, txuas lub rooj tsavxwm mus rau arduino. Ntawm qhov kawg ntawm cov zaub, cov xaim dub yuav tsum txuas rau hauv tus pin pin. Ntawm qhov kawg ntawm arduino, Kuv nyiam txuas rau A0, 5v, thiab Cov Pins Hauv Pem Hauv Ntej Cov Pob Zeb Pob Zeb.

Kauj Ruam 16: Kuaj thiab Txhawb Nqa thiab Ua Haujlwm

Cov Txheej Txheem Kuaj: Tig lub trimpot kom puv lub moos (koj tuaj yeem xav tig nws cov plaub hau rov qab). nyob rau Cov cim tuaj yeem qhwv hauv qhov tsis sib xws nyob ntawm qhov ntsuas ntawm koj lub LCD. Khawm pib dua yuav luam tawm cov cim kev cai thaum ua rau lub teeb pom kev zoo rau ib pliag Ob qho LCD teeb tsa geometry thiab teeb pom kev zoo nyob hauv kev tswj software, yog li lub teeb pom kev zoo yuav nyob tawm kom txog thaum qhib los ntawm software hais kom ua. Saib phanderson cov lus txib teeb tsa, thiab software demo, ntawm moderndevice.com kom paub ntau ntxiv. hauv qab ntawm nplooj ntawv no. Koj yuav zoo li yuav tsum tau hloov qhov kos duab los xav txog koj tus pin kev sib txuas lus. Qhov zaub yuav tsum pib sai tom qab kev ua haujlwm tiav. Kho qhov sib txawv resistor kom txog thaum koj zoo siab nrog cov duab sib txawv. Qhov ntau cov ntaub ntawv ntawm kev ua haujlwm ntawm cov zaub thiab kev txhawb nqa rooj sab laj muaj nyob ntawm moderndevice.com.
