Kuv xav siv xov tooj los tswj lub rooj tsav xwm LED ua lub teeb liab tig. Yog li, ESP8266 yuav ua raws li Access Point, microcontroller thiab tseem yog server. Lub web server yuav muaj lub vev xaib yooj yim nrog 3 lub nyees khawm: Tig LEFT, QAB RIGHT, thiab Tig SOS. Cov ntawv yuav ntxig rau ntawm cov laug cam LED. Txog cov cai, Kuv tau sim ob lub tsev qiv ntawv saib xyuas zoo uas yog Arduino Core WiFi thiab ESP8266WebServer. Tus Tub Ntxhais WiFi tsis muaj qhov thov ua haujlwm zoo. Yog li kuv yuav tsum siv 'client.readStringUntil (r)' los nyeem qhov kev thov thiab nws qeeb heev. Tom qab ntawd, kuv hloov mus rau ESP8266WebServer lub tsev qiv ntawv thiab nws ua haujlwm tau zoo.

Kauj Ruam 1: Txuas lub Rooj Tswjhwm Saib LED mus rau 5V Cov Khoom Siv Hluav Taws Xob

Kauj ruam 2: Kev thaiv kab

Txuas tus PIN los ntawm MAX7219 mus rau NodeMCU

VCC - 5 v

GND - NCO

DIN - D7 - MOSI - GPIO 13

CS - D8 - GPIO 15

CLK - D5 - GPIO 14

Kauj Ruam 3: Xaiv Koj Lub Npe Board LED

Hauv qhov piv txwv no, Kuv siv FC16_HW. Nyeem ntxiv ntawm no

Kauj Ruam 4: Teeb Arduino IDE

Teeb tsa Arduino IDE
