Hauv qhov kev qhia no peb yuav siv NodeMCU Mini, OLED Lcd, thiab Visuino los tso tawm xov xwm tshiab txhua ob peb feeb los ntawm internet hauv LCD. Saib daim vis dis aus.

Kauj ruam 1: Yam Koj Yuav Tsum Tau

• NodeMCU Mini
• OLED Lcd
• Cov qhob cij
• Jumper xov hlau
• Visuino program: Rub tawm Visuino

Kauj ruam 2: Circuit Court

• Txuas GND los ntawm NodeMCU rau tus pin breadboard (gnd)
• Txuas 5V tus pin los ntawm NodeMCU rau tus pin breadboard (zoo)
• Txuas tus pin 0 (SCL) los ntawm NodeMCU rau OLED LCD tus pin (SCL)
• Txuas tus pin 1 (SDA) los ntawm NodeMCU rau OLED LCD tus pin (SDA)
• Txuas OLED LCD tus pin (VCC) mus rau tus pin breadboard (zoo)
• Txuas OLED LCD tus pin (GND) rau tus pin breadboard (GND)

Kauj Ruam 3: Pib Visuino, thiab Xaiv NodeMCU ESP-12

Txhawm rau pib ua haujlwm rau Arduino, koj yuav tsum muaj Arduino IDE teeb tsa los ntawm no:

Thov nco ntsoov tias muaj qee qhov teeb meem tseem ceeb hauv Arduino IDE 1.6.6. Nco ntsoov tias koj nruab 1.6.7 lossis siab dua, txwv tsis pub Cov Lus Qhia no yuav tsis ua haujlwm! Yog tias koj tsis tau ua raws cov kauj ruam hauv Cov Lus Qhia no teeb tsa Arduino IDE rau program ESP 8266!

Visuino tseem yuav tsum tau teeb tsa. Pib Visuino raws li pom hauv thawj daim duab Nyem rau "Cov cuab yeej" khawm ntawm Arduino tivthaiv (Daim duab 1) hauv Visuino

Thaum cov lus sib tham tshwm, xaiv "NodeMCU ESP-12" raws li qhia hauv daim duab 2

Tus tswv tsev: feeds.reuters.com

NTS: 1

Ntxiv Hloov Cov Ntawv (Hloov Chaw 1)

1. teeb "Los Ntawm Tus Nqi":
2. teeb "ToValue" kom khoob

Ntxiv Hloov Cov Ntawv (Hloov Chaw 2)

1. (saib daim duab) teeb "Los Ntawm Tus Nqi": TAB TAB
2. teeb "ToValue" kom khoob

• Ntxiv Cov Ntawv Ntev (TextLength2)
• Ntxiv ContainsText (ContainsText1)

1. Teeb "ntawv" tus nqi: TAB TAB

   (saib daim duab)

   • Ntxiv Nco Cov Ntawv

   • Ntxiv logic THIAB

   • Ntxiv AddValue

   1. teeb tus nqi: 1

      • Ntxiv CompareValue (CompareValue1)

        1. teeb "sib piv": ctSmallerOrEqual

        2. teeb "tus nqi": 2

        • Ntxiv CompareValue (CompareValue3)

          1. teeb "sib piv": ctBigger
          2. set "tus nqi": 3

          Kauj Ruam 6: Hauv Visuino: Txuas Cov Khoom Siv
