2024 Tus sau: John Day | [email protected]. Kawg hloov kho: 2024-01-30 09:26
Hauv txoj haujlwm no koj yuav kawm paub txuas Arduino cov duab digital rau koj li ESP8266 lub rooj tsavxwm thiab yuav ua li cas thiaj pom IP chaw nyob ntawm cov zaub.
Khoom siv
Yam uas koj xav tau:
1. Pawg ESP8266
2. Arduino cov duab digital
3. Jumper xov hlau (ncig 20)
4. Cov khoom siv hluav taws xob, cov zaub xav tau 5v thiab pawg thawj coj yuav siv 3.3v
5. Ib UART qaum thiab USB qaum
6. (Tsis teb los tau) Potentiometer (siv los hloov qhov sib piv ntawm lub rooj tsavxwm)
7. (Software) USB rau UART Choj Tsav Tsheb (muaj nyob ntawm no:
Kauj Ruam 1: Hlau Rooj Tswjhwm Saib
Thawj kauj ruam hauv tus txheej txheem yog thaiv lub rooj tsavxwm. Txog qhov no koj tuaj yeem ua raws cov kab hluav taws xob uas tau qhia hauv cov khoom siv hluav taws xob lab sim arduino. Tsuas yog siv ESP8266's GPIO pins hloov ntawm Arduino tus pin. Yog tias koj muaj Arduino ntawm tes ces siv nws 5 volt thiab tus pin hauv av los txhawb lub zog tso saib. Yog tias koj tsis yog li ntawd tsuas yog xyuas kom siv lub 5 volt fais fab mov los ua lub zog tso saib. Tsis txhob siv ESP8266 los ua lub zog tso saib, nws yuav tsis muaj qhov hluav taws xob txaus.
Kauj Ruam 2: Program Board
Cov kauj ruam tom ntej yog sau cov cai rau pawg thawj coj saib. Nov kuv tau muab cov cai sau los ntawm kuv tus phooj ywg (txhua qhov credit mus rau Steven Mu rau qhov no). Dab tsi nws tau ua tiav suav nrog plaub lub tsev qiv ntawv nyob rau sab saum toj - thawj qhov yog ua cov lus txib rau lub vijtsam lcd thiab lwm yam peb rau ESP's wifi cov lus txib. Nws kuj tsim cov kev hloov pauv rau wifi nws xav txuas rau thiab nws tus password. Nws kuj tseem piav qhia qhov hloov pauv rau ntau yam pins ntawm lub vijtsam lcd. Tom ntej no nws txuas nrog lub wifi, nug nws tus IP chaw nyob, tom qab ntawd luam tawm nws mus rau qhov screen.
Kauj Ruam 3: Xeem
Yog tias txhua yam mus tau yooj yim IP chaw nyob yuav tsum luam tawm mus rau lub vijtsam lcd. Yog tias tsis yog, xyuas kom paub tseeb tias koj cov kev sib txuas tau zoo thiab koj cov pins raug.

Txaus Siab Rau Koj Tus Kheej Tsuas Yog Siv 12V-rau-AC-kab Inverter rau LED Lub Teeb Hluav Taws Xob Tsis txhob Rov Ua Rau Lawv rau 12V.: 3 Cov Kauj Ruam
Txaus Siab Rau Koj Tus Kheej Tsuas Yog Siv 12V-rau-AC-kab Inverter rau LED Lub Teeb Hluav Taws Xob Tsis txhob Rewiring Lawv rau 12V: Kuv txoj kev npaj tau yooj yim. Kuv xav txiav cov phab ntsa uas siv hluav taws xob LED teeb ua ib daim ces rov txuas nws kom khiav tawm 12 volts. Lwm txoj hauv kev yog siv lub zog hloov pauv, tab sis peb txhua tus paub tias lawv tsis muaj txiaj ntsig zoo, puas yog? Txoj cai? Los yog lawv?
