For making IoT devices you have to need NodeMCU. In This instructable We have setup NodeMCU board on Arduino IDE. it’s very Easy.

Step 1: Parts & Tools

Parts

NodeMCU
USB cable

Tools

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

3. After click on preference window will appear

4. In this window in additional board manager URLs

5. Copy this link

http://arduino.esp8266.com/stable/package_esp8266c...

6. And click on OK.

7. Go to

Tools--> Board--> BoardManager

8. In this window in search box type ESP8266

9. And install it

10. After installing go to

11. Tools--> Board-->NodeMCU 1.0 12E

12. After it set the parameters in tools according to the following image

For Better understamding see the above image

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)

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);
}
