Peb tau pom nws muaj txiaj ntsig los txuas cov khoom siv nrog JST cable kom koj tuaj yeem txuas lawv yooj yim kom sib sau ua ke lossis pauv qhov yog tias ib feem tau ua puas thiab koj xav hloov nws. Koj tuaj yeem txuas koj lub cim LED ncaj qha rau koj lub arduino/microcontroller board yog tias koj xav txo qis, tab sis nws yuav nyuaj rau nkaum Arduino nyob tom qab ntawm daim duab kos npe.

1. Kawm paub yuav ua li cas Cuab Yeej Siv Adafruit Phau Ntawv Qhia rau Kev Txhim Kho Zoo Tshaj

Koj yuav tsum tau muab cov xov hlau txuas rau ntawm koj lub txuas los ntawm lub qhov hauv koj lub rooj tsav xwm arduino.

2. Muaj txoj hauv kev zoo koj LED matrix twb muaj 3-pin JST cable txuas rau tom qab ntawm matrix. JST qhov txuas uas koj xav siv yuav tsum tau sau lo lus DIN qhov uas cov xov hlau txuas nrog rau hauv lub matrix. Saib seb nws puas muaj lub ntsaws lossis lub qhov (socket) kawg ntawm qhov txuas. Koj yuav xav tau qhov rov qab kawg (xws li ntsaws lossis lub qhov) txuas rau koj lub rooj tsavxwm. Koj tus lej kuj tseem yuav muaj 2 xaim txuas rau ntawm qhov chaw ib yam li 3 tus pin txuas. Peb yuav tsis xav tau tus txuas rau txoj haujlwm no. Yog tias koj lub matrix tsis muaj JST txuas twb tau txuas nrog koj yuav tsum xaiv ib sab ntawm kab ntawv thiab muab nws txuas rau ntawm matrix ntawm DIN sib txuas cov xaim liab mus rau lub zog/qhov hluav taws xob, cov xov hlau nruab nrab rau cov ntaub ntawv, thiab xaim thib peb rau hauv av (NPE).

Yog tias muaj lwm qhov txuas (2 txoj kab txuas sib txuas, 3 xaim DOUT) ntawm qhov sib piv koj tuaj yeem tso lawv nyob ntawd. Peb yuav nkaum lawv nyob tom qab ntawm daim paib. Koj tseem tuaj yeem txuas ob daim ntawv kawm ua ke kom ntev dua kos npe rau ntawm daim ntawv loj dua.

3. Koj yuav tsum tau muab cov khoom sib txuas (ntsaws lossis ntsawb) JST txuas rau Arduino. Muaj peb lub xov hlau ntawm koj lub txuas. Ib qho yuav tsum yog liab thiab lwm tus yog dawb thiab ntsuab, lossis qee zaum daj lossis dub. Cov hlau liab txuas nrog lub zog, feem ntau sau tias 3V lossis 3.3V ntawm Arduino/board. Muab cov xaim liab qab tso los ntawm 3V lossis 3.3V qhov ntawm lub rooj tsavxwm thiab txuas rau lub rooj tsavxwm. Lwm qhov xaim sab nraud los ntawm koj 3 xaim JST yog xaim av. Tso qhov kawg ntawm cov xaim no hla lub qhov uas sau tias GND hauv koj lub rooj tsavxwm. Solder rau hauv qhov chaw. Cov xov hlau nruab nrab yog rau cov ntaub ntawv. Qhov no tuaj yeem txuas nrog txhua tus lej digital (PWM) ntawm koj Arduino lossis microcontroller. Peb yuav siv tus pin 6 rau txoj haujlwm no. Siv lub xaim hlau nruab nrab ntawm koj lub txuas rau tus pin 6 ntawm lub rooj tsavxwm.

4. Koj tsis tas yuav siv lwm cov xov hlau txuas mus rau arduino/board. Peb yuav siv USB cable rau lub zog thiab nws yuav txuas rau lub microUSB txuas ntawm lub rooj tsavxwm.

Ua ntej peb muab lub rooj tsavxwm tso rau ntawm daim paib peb yuav xav tau program nws. Koj yuav xav tau koj lub khoos phis tawj thiab cov ntaub ntawv USB rau microUSB cable (lub xov tooj uas tuaj nrog koj lub charger yuav tsuas yog rau lub hwj chim. Koj xav tau ib qho uas yog cov ntaub ntawv thiab lub zog).

1. Rub tawm Arduino IDE los ntawm https://www.arduino.cc/en/main/software. Yog tias koj tsis paub nrog Arduino software thiab code peb pom zoo kom koj sim qee qhov kev qhia ntawm Arduino lub vev xaib.

2. Koj yuav tsum ntxiv peb lub tsev qiv ntawv Arduino. Lawv tuaj yeem rub tawm los ntawm Arduino IDE.

2a ib. Qhib Arduino IDE.

2b ua. Siv cov ntawv qhia zaub mov nyob rau sab saum toj ntawm nplooj ntawv mus rau Sketch> suav nrog Lub Tsev Qiv Ntawv> Tswj Tsev Qhua …

2c xub. Qhov no coj mus rau Tus Thawj Saib Xyuas Tsev Qiv Ntawv. Hauv sab tes xis tshawb nrhiav bar tshawb rau "neomatrix". Tom qab ntawd nyem lub pob Install. Rov ua qhov kev tshawb fawb no thiab teeb tsa rau "neopixel" thiab "adafruit gfx library"

3. Rub tawm cov cai los ntawm cov ntawv qhia no - Peb tau suav nrog cov lej raws li cov ntawv rub tawm nrog cov lus qhia no. Cov ntaub ntawv Arduino yuav tsum muaj nyob hauv daim nplaub tshev uas muaj lub npe zoo ib yam li cov ntawv. Thaum koj rub tawm cov ntawv ntawm no thiab sim qhib nws koj yuav tau txais cov lus uas hais tias "Cov ntaub ntawv" blmNamesSignCode.ino "xav tau sab hauv daim duab kos npe hu ua" blmNamesSignCode ". Tsim daim nplaub tshev no, tshem cov ntawv, thiab txuas ntxiv mus?". Click Ok thiab tsim daim nplaub tshev. Peb kuj tseem suav nrog cov lej raws li cov duab hauv ntu no hauv qhov xwm txheej koj xav ntaus nws rau hauv Arduino IDE koj tus kheej.

4. Qhib.ino cov ntaub ntawv hauv Arduino IDE.

5. Hauv peb cov cai peb siv cov npe me me los ntawm #SayHerName phiaj los nqis tes. Koj tuaj yeem ntxiv cov npe ntawm poj niam thiab ntxhais uas tau raug tsim txom los ntawm kev ua phem rau Dub los ntawm kev ntxiv kab tom qab kab 41 thiab kev ua qauv zoo li cov npe hauv kab dhau los. Cov npe hauv Memoriam tuaj yeem pom ntawm no ntawm Kev Hais Nws Lub Npe phiaj xwm https://aapf.org/shn-inmemoriam. Lwm lub npe tau nco tseg ua ib feem ntawm Black Lives Matter Movement tuaj yeem nrhiav tau ntawm #SayTheirNames List https://sayevery.name/ thiab hauv Black Lives Matter Article ntawm Wikipedia

6. Txuas koj lub rooj tsavxwm rau hauv koj lub computer nrog USB/microUSB cable. Siv cov ntawv qhia zaub mov saum toj kawg nkaus xaiv Cov Cuab Yeej. Txav mus rau Pawg Thawj Coj thiab xaiv lub rooj tsav xwm twg koj siv. Tom qab ntawd xaiv Cov Cuab Yeej> Chaw Nres Nkoj los ntawm cov ntawv qhia zaub mov koj lub rooj tsav xwm yuav tsum cia li tshwm nyob rau hauv cov npe chaw nres nkoj. Yog tias nws tsis txheeb xyuas kom paub tseeb tias koj siv xov tooj cable los txuas koj lub rooj tsav xwm rau koj lub khoos phis tawj.

7. Nyem rau lub cim kos Txheeb xyuas. Qhov no yuav suav cov duab kos thiab yuav qhia rau koj paub yog tias muaj teeb meem.

8. Nyem rau ntawm txoj cai xub Upload khawm kom rub qhov program mus rau koj Arduino.

9. Tshem lub rooj tsavxwm ntawm lub computer.

10. Txuas koj Arduino mus rau LED matrix siv JST txuas. Txuas Arduino mus rau lub txhab nyiaj fais fab/roj teeb siv USB/USBmicro cable. Xyuas kom tseeb tias koj lub roj teeb thiab lub rooj tsav xwm tau qhib yog tias lawv muaj lub qhov hluav taws xob qhib/tua. Yuav tsum muaj LED nyob ntawm Arduino uas qhia rau koj paub tias nws muaj hwj chim thiab tau qhib. Qee cov laug cam siv ob peb feeb los pib. Cov npe yuav tsum cia li pib ntxig rau ntawm LED matrix.

Teeb meem:

Koj puas muaj hwj chim/yog koj lub roj teeb them? Puas yog txhua yam txuas nrog? Koj qhov kev sib txuas zoo li cas? Koj puas tau sib xyaw cov xov hlau kom koj Arduino tsis txuas nrog koj cov lej? Yog tias txhua yam nyob hauv thiab tsis muaj qhov scrolling, koj puas tau rub koj lub program rau Arduino?

Koj tau pib teeb tsa koj daim ntawv kos npe hauv ib qib dhau los thiab sab laug chav rau LED matrix. Tam sim no peb yuav muab tso rau ntawm cov lej thiab muab cov xov hlau hla mus rau tom qab ntawm qhov kos npe.

1. Tshem tawm Arduino los ntawm LED matrix ntawm JST txuas.

2. Muab lub matrix tso rau hauv qhov chaw qhib rau ntawm lub hauv ntej ntawm daim paib nrog cov xov hlau nyob nruab nrab ntawm cov lej thiab daim duab los qhia.

3. Qaij tus lej thiab siv tus xaum lossis tus cim, cim qhov twg cov xov hlau yuav tsum hla lub cim. Tej zaum koj yuav muaj xov hlau ntxiv rau DOUT, kos rau cov ntawd kom lawv mus tom qab daim duab los.

4. Tshem qhov matrix. Siv lub tiaj tiaj thiab rab riam nyiam lossis lub thawv txiav, ua tib zoo txiav qhov me me uas txhua qhov koj cov xov tooj yuav tsum hla mus rau tom qab ntawm daim paib.

5. Ua tib zoo rub cov hlua hla mus rau tom qab.

6. Ntxiv cov kab xev nplaum ob sab los yog ob tog ua npuas daim kab xev rau sab nraum qab ntawm LED matrix. Siv lub zog ruaj khov los kaw kab ntawv hauv qhov chaw ntawm sab xub ntiag ntawm koj daim ntawv kos duab.

Kauj Ruam 5: Ua tiav Qhov Kos Npe thiab Txhawb Nqa

Tiav Qhov Kos Npe thiab Txhawb Nqa
Tiav Qhov Kos Npe thiab Txhawb Nqa

1. Txuas Arduino/pawg thawj coj saib dua rau sab nraub qaum ntawm koj daim paib. Koj tuaj yeem siv daim kab xev npog lossis kab xev hluav taws xob los pab tuav cov kab txuas thiab xov hlau ntxiv. Peb kuj siv qee daim kab xev hluav taws xob qhwv ib puag ncig ntawm pawg thawj coj los ua kev tiv thaiv me ntsis. Koj yuav xav tau 3D luam tawm rooj plaub rau kev tiv thaiv ntau ntxiv rau Arduino.

2. ntsaws koj lub roj teeb rau hauv Arduino thiab tig lub cim kom ntseeg tau tias koj lub zeem muag tau teeb thiab nqes lus.

Kev daws teeb meem: Puas yog koj qhov kev sib txuas nruj thiab rau qhov txuas sib txuas raug? Koj lub roj teeb puas muaj hwj chim?

Kev tawm tswv yim

Txoj haujlwm no tau ua rau Black Lives Matter kev txhawb nqa thiab tseem nco txog poj niam thiab ntxhais hluas uas tau raug tua los ntawm kev ua phem rau Dub. #SayHerName phiaj los nqis tes muaj Kev Xav Tau thiab Txoj Cai Txoj Cai los hloov pauv qhov tseeb ntawm https://aapf.org/shndemands.
