Cov no yog cov lus qhia ib qib zuj zus rau kev sib dhos 8x8 LED Board cov khoom siv los ntawm moderndevice.com. Kuv yeej tsis tau ua si nrog cov lus qhia ua ntej siv cov khoom siv no. Kuv hais qhia kom nyeem dhau txhua qhov kev sib dhos ua ntej pib pib ua kom tawg vim hais tias kev sib dhos txiav txim tsis muaj teeb meem nrog cov khoom siv no. Xaiv, qhov no yog kev sib dhos yooj yim heev. Nws muaj qee qhov ntsiab lus uas xav tau kev saib xyuas tshwj xeeb.

Kauj Ruam 1: Siv cov LEDs

Qhov no yog, nyob deb, siv sijhawm ntau tshaj plaws ntawm kev sib dhos. Muaj kev saib xyuas tshwj xeeb rau qhov tsis sib xws ntawm txhua LED thiab ua kom paub tseeb tias koj tsis muaj cov kab mob sib txuas txias. Koj yuav tso IC qhov nyob rau ntau qhov ntawm cov khoom sib txuas thiab, yog tias koj tau txais qee yam tsis raug, nws yuav kho kho nyuaj heev. Kuv xaiv cov LED ntsuab vim lawv pheej yig tshaj kuv pom. Koj tuaj yeem siv lwm yam xim, tab sis yuav tsum paub txog cov kev xav tau tam sim no ob qho hauv kev xaiv tiv thaiv thiab lub zog siv. Cov LEDs tau muab tso rau ntawm NON-print sab ntawm lub rooj tsavxwm. Kuv tau txais ua ntej ntawm kuv tus kheej thaum kuv pib ua ntej thiab tso ob peb kab ntawm qhov tsis raug ntawm pawg thawj coj saib. De-soldering TSIS YOG lom zem! Moderndevice.com piav qhia cov txheej txheem ntsuas hauv qab no rau LEDs. Qhov tseeb yuav tsum paub, Kuv nyuam qhuav dhau los thiab tshuaj xyuas qhov sib koom tes thiab kev qhia ntawm txhua tus LED ua ntej cov kauj ruam tom ntej. Yog tias koj hla kev sim, nco ntsoov koj yuav pom koj tus kheej nrog txoj haujlwm de-soldering nyuaj yog tias muaj qee yam tsis raug. Kev Xeem: Clip 470 - 1000 ohm resistor rau hauv tus nab kuab dub -clip xeem txhuas. Txuas lwm qhov kawg ntawm qhov kev ntsuas no coj mus rau hauv av ib sab ntawm 5-6V fais fab mov. Tom ntej txuas ib kawg ntawm tus liab liab tus yeeb yaj kiab clip xim coj mus rau qhov zoo, +5V sab ntawm koj lub zog siv. Txiav lwm qhov kawg ntawm qhov liab no, coj mus rau ib qho ntawm "+5V" daim ntawv lo qhov nyob ntawm ib sab ntawm 8x8LED board. Looping ib daim xaim hla lub qhov thiab ntswj nws rov qab rau nws tus kheej, yuav ua lub davhlau ya nyob twg yooj yim uas txhawm rau txhawm rau ntsuas qhov ntsuas zoo. Us siv qhov kawg ntawm qhov av-ua tus tiv thaiv tiv thaiv raws li kev sojntsuam, ua tib zoo teeb txhua lub teeb LED. Qhov no tuaj yeem ua tiav yooj yim los ntawm cov pawm uas tus neeg tsav tsheb chips yuav thaum kawg nce.

Kauj Ruam 2: Cov Capacitors

Soj ntsuam kev qhia kom raug, muab tshuaj txhuam hauv peb 47 ufd, 25 volt electrolytic capacitors.

Kauj Ruam 3: IC Qhov Ntsuas

Muab cov IC tso rau ntawm lub rooj tsavxwm thiab muab tshuaj txhuam ua ob kab. Txheeb xyuas qhov chaw nyob ntawm lub qhov (socket). Cov thais ntawm lub qhov (socket) yuav tsum tau ntsib lub capacitors. Thaum koj zoo siab nrog qhov muab tso rau ntawm lub qhov (socket), ua kom tiav cov laug.

Kauj Ruam 4: Cov Tiv Thaiv

Solder hauv plaub plaub 1k ohm resistors. Kev taw qhia tsis muaj teeb meem.1k resistors tau muab nrog cov khoom siv thiab siv rau 20mA LEDs. Yog tias koj siv LEDs nrog cov duab sib txawv tam sim no, xav tau cov sib txawv sib txawv.

Kauj Ruam 5: Ntau Capacitors

Solder hauv plaub.1 ufd (104) monolithic capacitors. Kev taw qhia tsis muaj teeb meem.

Kauj Ruam 6: ICs

Ntxig rau ICs hauv lub qhov muag ua tib zoo saib kom raug. Cov thais hauv txhua lub nti yuav tsum ntsib lub capacitors. Koj yuav zoo li yuav tsum tau khoov cov coj me ntsis kom lawv haum rau hauv lub qhov (socket).

Kauj Ruam 7: Txiav Headers

Koj yuav xav tau yam tsawg kawg ntawm teeb ntawm poj niam lub taub hau uas koj tuaj yeem ntsaws rau hauv tus tswj hwm arduino. Trim tawm 9 tus poj niam lub taub hau.

Kauj Ruam 8: Txhim Kho Lub Taub Hau

Txij li thaum kuv tau piggybacking BBB Kuv tau siv lub taub hau rau sab xis ntawm lub rooj tsavxwm. Cov pinouts ntawm no yog, saum toj mus rau hauv qab, Cov Ntaub Ntawv Tawm (DO), Cov Ntaub Ntawv Hauv (DI), Moos (CLK), Tso Tawm Kom Haum (OE), Latch (LE), 2 tus pin tsis siv, +5 volts (+5v), thiab Hauv av (GND). Koj muaj peev xwm ua kom muaj zog ib pawg 8x8 ntawm BBB. Yog tias koj xaiv daisy saw laug cam, Kuv hais qhia kom nyeem Cov Lus Qhia (PDF ceeb toom) rau pawg thawj coj. Koj yuav tsum nco ntsoov xaiv qhov khoom siv hluav taws xob raug rau koj txoj haujlwm. Kuv tuaj yeem lees paub qhov tseeb qhov tsis muaj zog ntau yuav qhia tus cwj pwm tsis zoo. Koj tuaj yeem pom cov hlua txuas uas pom ntawm BBB hauv cov duab hauv cov lus qhia hauv pawg thawj coj saib. Tsis quav ntsej lub jumper tshwj tsis yog koj muaj Rev. C BBB laus dua.

Kauj Ruam 9: Tshaj Tawm Koj Cov Phiaj Xwm

Raws li tau hais yav tas los, koj tuaj yeem teeb tsa cov laug cam yooj yim los ntawm kev txuas DO ntawm ib pawg thawj coj mus rau DI ntawm qhov txuas ntxiv, nrog rau CLK. OE, LE, +5v thiab GND kab. Kuv yooj yim siv cov khoom sib xyaw ua ke ua cov dhia. Qhov loj tshaj ntawm no yog qhov tsim nyog siv hluav taws xob. Koj yuav tsis muaj peev xwm ua qhov no los ntawm USB chaw nres nkoj. Ib qho 5-6 volt REGULATED fais fab mov tuaj yeem tswj tau 6 pawg pawg.

Kauj ruam 10: Programming

Kuv tau txais kev ncaws pob loj tawm ntawm daim duab arduino muab los ntawm moderndevice.com. Nws scrolls Asimov's Peb Txoj Cai ntawm Neeg Hlau. Kuj tseem muaj lub cim tsim hluav taws xob siv hluav taws xob. Qhov chaws tau thauj mus rau Arduino (clone) ib txwm muaj. Cov zaub yuav tsum pib sai li sai tau thaum lub microcontroller rov pib dua.
