2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26

Nyob zoo sawv daws! Thaum kawg ntawm qhov kev qhia no koj yuav paub tsim koj tus kheej phab ntsa LED.

Qhov kev qhia no yog ua raws lub caij ntuj sov muaj nyob hauv Tsev Kawm Ntawv Dawb Huv Lub Plawv.

Muaj kev lom zem!

Khoom siv

Cov khoom siv muaj npe hauv qab no.

Kauj Ruam 1: Cov khoom siv

Cia peb pib los ntawm kev sau txhua yam peb xav tau kom ua tiav Peb Cov Phab Ntsa Led:

(Cov ntawv txuas tau tsim los ntawm 7/10/2019)

Arduino IDE Software

ESP32 Micro Controller

LED Pixel Lub Teeb

Hwj chim Mov

Fais fab Qaum

Hlau Stripping Tool

Breadboard Jumper Cables

Cov xov hluav taws xob

Kauj Ruam 2: Txheeb Xyuas Txoj Cai Fais Fab Rau Koj LedWall

Muaj ib txoj hauv kev ua lej yooj yim kom paub seb lub hwj chim twg yog qhov zoo tshaj rau koj siv.

Peb tab tom siv Ohm txoj cai lij choj lub zog: P = IxV (Lub zog = Siv zog x Voltage)

Kev ntsuas hluav taws xob tau txiav txim siab los ntawm peb cov coj: hauv qhov no 5V.

Kev siv zog nyob ntawm qhov kho vajtse, ib leeg coj los siv 30mA.

Txhua kab ntawm 50 Leds yog li haus 50 x 30mA = 1250mA = 1.25A.

Peb 500 Led phab ntsa yog li siv 10 zaug uas (10 kab ntawv): 12.5A.

Kev siv fais fab yog 5V x 12.5A = 62.5W rau Leds.

Tau kawg, nyob rau sab saum toj ntawm Leds koj yuav tsum tau suav nrog rau ESP thiab txhua lwm yam khoom ntawm koj qhov Circuit.

Peb muaj 60A fais fab mov, peb muaj ntau ntau tshaj qhov peb xav tau.

Kauj Ruam 3: Lub Hwj Huam Hluav Taws Xob

Peb lub zog xa khoom tuaj nrog cov xaim txuas. Peb yuav tsum hloov kho lub hwj huam qaum los txuas nws rau 110V ntsaws.

- Txiav tus poj niam txuas ntawm lub hwj chim qaum. Peb yuav khaws tus txiv neej, txwv tsis pub paub zoo li NEMA 5-15P.

- Siav kab kom muaj txog 3 hli tooj liab pom ntawm txhua lub xov hlau.

Nov yog cov vis dis aus qhia nrawm yuav ua li cas kom tshem cov xov hlau:

Kauj Ruam 4: Txuas Cov Khoom Siv Hluav Taws Xob

Tam sim no peb tau npaj los xaim peb cov khoom siv hluav taws xob!

Nco ntsoov tshem lub hwj huam hluav taws xob thaum ua haujlwm rau nws.

Thaiv

• Cov xaim dub (Phase) txuas rau lub zog hluav taws xob 'L' tus pin
• Cov xaim dawb (Neutral) txuas rau lub zog hluav taws xob 'N' tus pin
• Cov xaim ntsuab txuas rau lub zog hluav taws xob tus pin 'Hauv av'

(Yog tias koj lub xov tooj hluav taws xob sab hauv tsis zoo ib yam li peb li kev nyab xeeb thiab saib cov duab hauv online.)

Kev Xeem

Txuas lub tshuab fais fab hauv lub computer mus rau txhua lub qhov hluav taws xob. Lub ntsuab LED ntawm lub hwj chim yuav tsum qhib.

Kauj Ruam 5: Hwj chim rau ESP32S

Saib ntawm koj li ESP yuav tsum muaj daim ntawv lo nyob ib sab ntawm txhua tus pin.if nws tsis muaj daim ntawv lo koj tuaj yeem saib 'pinout' ntawm koj tus kheej ESP online.

Siv tus txiv neej mus rau poj niam lub rooj noj mov jumper xaim lossis xaim hluav taws xob, txuas:

• Tus '5V' ESP32S tus pin rau '+V' ntawm lub hwj chim (txiv kab ntxwv hauv daim duab saum toj no)
• 'GND' ESP32S tus pin rau ntu '-V' ntawm lub hwj chim (dub hauv daim duab saum toj no)

(Ntawm qee qhov ESPs tus '5V' tus pin tau sau tias 'VCC' hloov chaw, ob qho tib si txhais tib yam nkaus.)

Thov nco ntsoov tias koj li ESP yuav muaj qhov sib txawv 'pinout' dua li qhov peb siv. Yog li koj tuaj yeem txuas koj cov xov hlau mus rau qhov chaw sib txawv dua li ntawm daim duab saum toj no. Tsuav koj txuas mus rau tus pin raug (5V & GND), qhov chaw nyob ntawm lub rooj tsavxwm tsis muaj teeb meem.

TestingPlug hauv koj lub zog txuas ntxiv, thiab yog tias koj li ESP muaj qhov taw qhia LED (feem ntau ua), nws yuav ci kom pom lub zog tau xa mus rau ESP. Nrog koj zoo siab!

Kauj Ruam 6: Ua kom lub teeb ci LED

Siv cov xov hluav taws xob:

- Txuas cov xaim liab ntawm LED Teeb Sawb rau V+ ntawm lub hwj chim.

- Txuas cov xaim xiav ntawm LED Teeb Sawb mus rau V- ntawm lub hwj chim.

Kauj Ruam 7: Txuas ESP32 mus rau LED Teeb Sawb

Peb ESP32 qhia rau WS2811 tus neeg tsav tsheb txuas nrog rau txhua tus coj cov xim thiab ci ci uas lawv xav tau kom ua.

Leds strips tuaj nrog 3 xaim txuas:

- Liab: Hwj chim- Xiav: Neutral- Dawb: Cov ntaub ntawv

Wb txuas Cov Hluav Taws Xob Dawb coj mus rau tus lej digital ntawm ESP. Thov nco ntsoov tus lej PIN xaiv raws li peb yuav xav tau xaiv nws hauv tus lej tom qab. Peb txuas peb tus lej rau tus pin 13.

Kauj Ruam 8: Npaj Khoos Phis Tawj: C2102 Driver

Tam sim no tias peb lub khoos phis tawj muaj xov txuas, peb xav xa peb thawj tus lej los sim nws. Los ntawm lub neej ntawd, Windows lossis MacOs tsis tuaj yeem sib txuas lus nrog peb ESP32. Ua li ntawd, peb yuav tsum rub tawm "tus tsav tsheb" rau ESP USB kev sib tham nti: ua c2102.

Tus tsav tsheb no yuav tsum rub tawm thiab teeb tsa:

- Windows 10: https://www.silabs.com/documents/public/software/C…- Windows 7/8/8.1:

(Txuas li ntawm 7/10/2019)

Kauj Ruam 9: Arduino Software - Ntxiv ESP32 Support - Kauj Ruam 1

Ua ntej peb tuaj yeem siv peb ESP32 nrog Arduino software, peb yuav tsum ua kom ntseeg tau tias nws tau lees paub.
