Step 1: Parts & Tools

Parts

1. NodeMCU

2. USB cable

Tools

1. Arduino IDE

 

If you don't download Arduino IDE First download it from the following link according to your OS from the following link--

https://www.arduino.cc/en/Main/Donate

Step 2: Setup Arduino IDE for NodeMCU

1.Open it & click on

2. File--> preference( Figure-1)

3. After click on preference window will appear

4. In this window in additional board manager URLs(Figure2- Figure-3 )

5. Copy this link

http://arduino.esp8266.com/stable/package_esp8266com_index.json

6. And click on OK.

7. Go to

Tools--> Board--> BoardManager( Figure 4)

8. In this window in search box type ESP8266(Figure-5 )

9. And install it

10. After installing go to

11. Tools--> Board-->NodeMCU 1.0 12E(Figure -6 )

Step 3: Check Your NodeMCU

• For Check the NodeMCU

• Connect your NodeMCu with laptop or PC via USB cable

• Open your ArduinoIDE

• Go To

• Tools-->port

• And select the port

Step 4: Code(Upload the Following for Check the NodeMCU With Blinking of Inbuilt LED on D0)

( See in Figure-8)

int LED = D0;

void setup(){

Serial.begin(115200);

pinMode(LED,OUTPUT);

}

void loop(){

digitalWrite(LED,HIGH);

delay(1000);

digitalWrite(LED,LOW);

delay(800);

digitalWrite(LED,HIGH);

delay(600);

digitalWrite(LED,LOW);

delay(400);

digitalWrite(LED,HIGH);

delay(200);

digitalWrite(LED,LOW);

}
