Txoj hauv kev yooj yim no tso cai rau koj ua LCD teeb pom kev zoo ntawm cov xim thiab qhov loj los coj qhov tshiab rau lub cuab yeej qub.

Kauj Ruam 1: Cia Ua Ib Yam

Cia Ua Ib Yam
Cia Ua Ib Yam

Rau txoj haujlwm no koj yuav xav tau daim yas yas pob tshab, LEDs, tus tiv thaiv thiab qee cov xaim ntxiv rau cov cuab yeej sib txawv thiab ob peb txhais tes ncaj;-)

Kauj ruam 2: Coj nws sib nrug

Coj Nws Los
Coj Nws Los

LCD muaj PCB, hlau thav duab thiab ua kua iav ua ke.

Kauj ruam 3: Rub daim tawv nqaij tawm

Sab nraub qaum ntawm iav iav tau npog nrog cov yeeb yaj kiab zoo nkauj heev, uas yuav tsum tau muab tshem tawm.

Kauj ruam 4: Ooo! Tsis Rush! Xav Ua Ntej

Oops! Tsis Rush! Xav Ua Ntej
Oops! Tsis Rush! Xav Ua Ntej

Kuv qhov yuam kev yog tias kuv tau tshem cov lim polarizing ua ke nrog zaj duab xis rov qab. /Liquid_crystal_display

Kauj Ruam 5: Tau Txais Nws

Tau Nws Txiav
Tau Nws Txiav

Tom ntej txiav daim duab plaub yas.

Lub ntsej muag xuab zeb thiab sab nraub qaum ntawm cov phaj yas nrog cov ntawv nplaum zoo rau lub teeb pom kev zoo tom qab ntawd txiav cov nqais ntawm ob sab ntawm phaj uas koj npaj yuav nruab LEDs. Cov duab ntawm LED yuav tsum tau tsim nrog cov ntawv kom haum rau hauv qhov thais

Kauj Ruam 6: Cia Li Xyaum Qee LEGO;-)

Cia Peb Xyaum Qee LEGO;-)
Cia Peb Xyaum Qee LEGO;-)

Tej yam zoo li ntawd.

Koj tuaj yeem siv cov kua nplaum kub los ua kom nws ruaj khov.

Kauj Ruam 7: Cia Peb Sim Nws …

Cia Peb Muab Nws Mus Sim …
Cia Peb Muab Nws Mus Sim …

Tsis phem rau kuv;-)

Kauj Ruam 8: Nqa tag nrho cov luav mus rau hauv lub tawb

Nqa tag nrho Bunnies rau hauv lub tawb
Nqa tag nrho Bunnies rau hauv lub tawb

Tam sim no txhua yam tau npaj los sib sau ua ke:

-PCB; -Cov ntawv dawb los cuam tshuam lub teeb rov qab; -polarizing lim (yog tias koj tshem nws ua yuam kev); -plastic phaj nrog kos LEDs; -tsom iav; -frame. NCO TSEG: Ceev faj nrog cov ntaub qhwv kub ntawm PCB thiab cov elastomer txuas (zebra strip). Siv cawv dawb los ntxuav nws yog tias koj kov koj cov ntiv tes. Lwm qhov tseem ceeb yog kev ua kom haum. Yog tias tom qab ua kom nws zoo koj tau txais cov kab uas ploj lawm (cim) ntawm LCD tom qab ntawd cov txuas tau hloov pauv los ntawm txoj haujlwm qub. Ua tib zoo sib cais thiab rov kho nws dua.

Kauj Ruam 9: Kauj Ruam Kawg

Kuv vam tias koj twb tau suav tus nqi ntawm cov resistors koj xav tau.

Yog li ntawd, solder nws. Muaj ob lub ntsiab lus kom tau txais lub zog rau LED los ntawm. Koj tuaj yeem txuas nws ncaj qha rau cov laj thawj siv zog (tus pin 0 - GND, tus pin 1 - 5V) ntawm LCD. Lossis koj tuaj yeem ua qhov sib txuas sib cais (ntawm kuv lub LCD muaj cov ntaub qhwv tsis siv rau lub teeb pom kev zoo) thiab qhov xwm txheej ntawd koj yuav tuaj yeem siv PWM teeb liab los tswj lub teeb ci ntawm LED.

Kuv tau siv cov txheej txheem zoo sib xws los hloov kho qhov ntsuas qhov sib txawv qub rau kuv qhov haujlwm tom ntej.
