Video: RGB LED MATRIX Siv NEOPIXEL: 8 Kauj Ruam (nrog Duab)
2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:25
Hauv qhov kev qhia no, kuv yuav qhia koj yuav tsim 5*5 RGB LEDMATRIX Siv NEOPIXEL li cas. Nrog cov lej no, peb tuaj yeem tso saib cov tsiaj ntawv ntxim nyiam, emojis thiab cov ntawv yooj yim dua txaus nyiam. cia peb pib!
Kauj ruam 1: Nta
- Me me heev
- Ntau lab xim
- Tsuas yog ib lub xaim xav tau rau lub cajmeem
- Super zoo nkauj
- Peb tuaj yeem tso tawm emojis, ua kom pom tseeb, ntawv
Kauj Ruam 2: Cov Ntaub Ntawv Xav Tau
- 25*neopixel LEDs (WS2812 5050smd)
- Arduino (ib qho Arduino)
- 3D luam tawm jig (koj tuaj yeem rub tawm.stl)
- Hlau
Kauj Ruam 3: Txog 5050 WS2812B LEDs
Txhua ws2812 coj muaj 4 tus pin
- Vcc (txuas rau 5v)
- Gnd
- Din (txuas rau Arduino)
- Ua (cov ntaub ntawv tawm txuas mus rau LEDs tom ntej hauv cov ntaub ntawv hauv)
Kuv tsis muaj ib tus neeg ws2812b LEDs yog li kuv txiav txim siab coj los ntawm ledstrip.
WS2812 LED strips yog qhov chaw nyob thiab programmable Flexible LED strips uas muaj txiaj ntsig zoo hauv kev tsim cov teeb pom kev zoo. Cov LED Sawb no tau siv los ntawm 5050 RGB LED nrog WS2812 LED tsav tsheb inbuilt hauv nws. Txhua LED siv 60mA tam sim no thiab tuaj yeem siv los ntawm 5V DC khoom siv. Nws muaj ib tus lej nkag cov ntaub ntawv tus pin uas tuaj yeem pub los ntawm cov koob digital ntawm Microcontrollers.
Nyob ntawm qhov siv ntawm peb tus neeg Liab, Ntsuab, thiab Xiav LEDs peb tuaj yeem tsim xim twg peb xav tau.
Saib qhov no yooj yim Video
Kauj Ruam 4: Daim duab Circuit Court
Kauj ruam 5: Ua
Ua ntej, tso neopixel coj hauv 5*5 matrix jig. Nco ntsoov tso txhua LEDs hauv tib txoj kev Qhia Tom qab tso tag nrho LEDs ntawm jig xub txuas txhua lub hauv paus ntawm txhua tus LEDs ua ke. Tom qab ntawd txuas VCC ntawm txhua LEDs ntawm kab. Ua tib yam rau cov kab uas seem. Tom qab ua tiav qhov txuas cov ntaub ntawv tawm ntawm thawj coj mus rau cov ntaub ntawv hauv kev coj ua tom ntej. Cov ntaub ntawv tawm ntawm txhua kab txuas rau kab tom ntej ua ntej LEDs. Rov ua qhov no rau txhua qhov LEDs. Tom qab ua tiav txhua yam. txuas txhua kab VCC ua ke thiab hauv av. Thaum kawg txuas cov xov hlau rau ib qho gnd, VCC, cov ntaub ntawv hauv.
Kauj Ruam 6: Cov ntaub ntawv kaw
Tom ntej no, Kuv tau ua lub thawv me me nrog cov ntawv ua npuas ncauj. Thiab tso lub matrix rau hauv rooj plaub ua npuas ncauj.
Kev sib txuas rau Arduino
Vcc to 5V
Gnd rau gnd
Din rau D7 (txhua tus lej digital)
Qhov ntawd yog txhua yam hais txog kev sib txuas kho vajtse
Kauj Ruam 7: REST IS IN PROGRAMMING
ua ntej, teeb tsa lub tsev qiv ntawv nrawm
Peb tuaj yeem ua haujlwm txhua tus coj seperatley.with kev pab ntawm lub tsev qiv ntawv coj nrawm peb tuaj yeem tsim cov duab sib txawv thiab cov cim.
Thov saib qhov no neopixel pib Video
Koj tuaj yeem rub tawm.stl, cov lej cim ua cim, ntsuas tus lej los ntawm no
Tom qab xa cov cai rau Arduino yuav tsum siv lub zog 1.5-ampere. Qhov siab tshaj qhov ci ci neopixel coj teeb ib ncig 60 mA tam sim no.we muaj tag nrho 25 LEDs yog li 25*60 = 1.5A
Kauj Ruam 8: Cov phiaj xwm yav tom ntej
- Npaj ua ib qho software yooj yim los tsim cov cai
- Bluetooth txuas thiab tswj
Ua tsaug….
