Hauv kuv qhov kev qhia yav dhau los, Kuv tau hloov lub wireless siv ESP8266. tsab xov xwm tuaj yeem nyeem ntawm no "Yuav Ua Li Cas Hloov WiFi Siv ESP8266".
Hauv tsab xov xwm no, Kuv tsuas yog ua ib-channel wireless hloov.
Thiab hauv kab lus no kuv yuav qhia koj yuav ua li cas hloov lub wireless uas muaj ntau dua ib qho channel.
Piv txwv li kuv yuav ua peb txoj kev hloov pauv wireless.
Txog cov khoom siv, nws tseem zoo ib yam li tsab xov xwm dhau los. Tab sis nws yog qhov yuav tsum tau ntxiv Cov Tiv Thaiv thiab LEDs rau qhov ntsuas qhov ntsuas.
Kauj Ruam 1: Yuav Tsum Muaj Kev Koom Tes
Cov khoom koj xav tau rau qhov kev qhia no:
- NodeMCU ESP8266
- 3 X 5mm LEDs
- 3X resistor 330 Ohm
- Jumper Hlau
- Pawg Thawj Coj
- Micro USB
- Laptop
Kauj Ruam 2: Sib Sau Ua Ke Txhua Yam
ntawm no kuv siv 3 chaw nres nkoj los ntawm esp8266.
yog:
D0 ua Led 1
D1 li coj 2
D2 ua Led 3.
rau cov phiaj xwm ib-channel thiab 3-channel tsuas yog sib txawv ntawm cov lej LEDs siv. yog li daim duab saum toj no tuaj yeem sawv cev rau cov phiaj xwm rau qeb 3 ntawm.
Kauj ruam 3: Programming
qhov hloov pauv uas kuv tau ua tsuas yog siv tau ntawm lub network hauv zos. vim kuv tsis koom nrog internet los hloov qhov no.
Kuv tau muab cov duab kos uas tuaj yeem rub tawm hauv qab no
Kauj Ruam 4: Nkag Mus Rau Lub Vev Xaib
Nov yog yuav ua li cas khiav lub wireless hloov no:
Tom qab Sketch upload ua tiav
- Qhib Wifi ntawv qhia zaub mov ntawm lub xov tooj hauv
- Txuas lub xov tooj hauv xov tooj mus rau SSID "NodeMCU"
- Qhib Serial Monitor ntawm Arduino
- Saib tus IP chaw nyob tso tawm
- Qhib qhov browser ntawm lub xov tooj Android
- Nkag mus rau tus IP chaw nyob ntawm tus saib xyuas ntu (192.168.4.1)
Tom qab ntawd lub vev xaib yuav tshwm los tswj lub LED
Kauj ruam 5: Qhov tshwm sim
Txhawm rau qhib LED, nyem lub pob "on"
Txhawm rau tua LED, nias lub pob "tua"

Yooj Yim Tilt-Raws Xim Hloov Wireless Rubik Lub Teeb Lub Teeb: Hnub no peb tab tom tsim qhov txaus Rubik lub Cube-esque teeb uas hloov xim raws sab twg. Lub voos xwmfab khiav ntawm lub roj teeb LiPo me me, them los ntawm tus qauv micro-usb cable, thiab, hauv kuv qhov kev sim, muaj roj teeb lub neej tau ob peb hnub. Qhov no
Yuav Ua Li Cas Tswj ESP8266 Raws Li Sonoff Basic Hloov Hloov Nrog Lub Xov Tooj: 4 Cov Kauj Ruam (nrog Duab)
Yuav Ua Li Cas Tswj ESP8266 Raws Li Sonoff Basic Smart Switch Nrog Lub Xov Tooj: Sonoff yog kab kab rau Smart Home tsim los ntawm ITEAD. Ib qho ntawm cov khoom siv hloov pauv tau thiab pheej yig tshaj plaws los ntawm kab ntawd yog Sonoff Basic. Nws yog Wi-nkaus qhib kev hloov pauv raws li lub nti zoo, ESP8266. Kab lus no piav qhia yuav teeb tsa Cl
