Smart plug kya hai ?

Ek smart plug ek aisa device hai jo aapke electrical appliances ko aapke smartphone app se control karne ki permission deta hai. Is blog mein hum aapko batayenge kaise aap NodeMCU aur Blynk app ka use karke ek smart plug bana sakte hai.

 

Material jo aapko chaiye:

• NodeMCU board

• Relay module

•   Jumper wires

•   USB cable

 Blynk IoT app (Google Play or App Store se download karein)

 

•    Power Supply 230 Ac– 5v DC

·         Step 1: Circuit wiring

Sabse pehle circuit wiring karna hai. NodeMCU board ko relay module se jumper wires ka use karke connect karein. Wiring diagram niche diya gaya hai:

 

Relay module ke VCC aur GND pins ko NodeMCU board ke Vin aur GND pins se respectively connect karein.

Relay module ke IN1 pin ko NodeMCU board ke D1 pin se connect karein.

·      Step 2: Blynk app ko set up karein

Next, Blynk app ko set up karna hai. Neeche diye gaye steps follow karein:

 

1.    Blynk app mein ek naya project create karein.

2.    Project mein ek button widget add karein.

3.    Button widget par click karein aur output pin ko virtual pin V1 select karein.

 

·      Step 3: NodeMCU board ko program karein

 

Ab NodeMCU board ko program karna hai. Neeche diye gaye steps follow karein:

1.    Arduino IDE ko download aur install karein.

2.    Arduino IDE ko open karein aur board ko NodeMCU select karein.

3.    Neeche diye gaye code ko copy karke paste karein:

#include <ESP8266WiFi.h>

#include <BlynkSimpleEsp8266.h>

 

char auth[] = "your_auth_token";

char ssid[] = "your_wifi_ssid";

char pass[] = "your_wifi_password";

 

void setup()

{

pinMode(D1, OUTPUT);

digitalWrite(D1, HIGH);

 

Blynk.begin(auth, ssid, pass);

}

void loop()

{

Blynk.run();

}

 

"your_auth_token" ko aapke Blynk app project ke authentication token se replace karein.

"your_wifi_ssid" aur "your_wifi_password" ko aapke Wi-Fi network ke SSID aur password se respectively replace karein.

 

·      Step 4: Testing

Aapne upar ke sabhi steps complete kar liye hai, ab code ko NodeMCU board mein upload karein aur Blynk app ko open karein. Button widget par click karein aur relay module ke LED on/off hote hue dekhein.

 

Congratulations, aapne NodeMCU aur Blynk app ka use karke ek smart plug bana liya hai! Ab aap apne kisi bhi electrical appliance ko relay module se connect karke use apne smartphone se control kar sakte hai.

 

Important Safety Note: Kisi bhi electrical appliance ko plug karte se pehle, electrical connection ko switch off karna na bhulein.

 

Disclaimer (Warning):

Iss project ko follow karne se pehle, aapko safety aur local laws ke baare mein sochna chahiye aur kisi expert ki madad le sakte hai. Agar aap iss tutorial ko follow karte hai, toh aap aasaani se apne khud ke smart plug ko bana sakte hai.

 

Conclusion

NodeMCU aur Blynk app ka use karke ek smart plug banane ka project bahut hi easy aur interesting hai. Kuch simple steps follow karke aap ek smart plug bana sakte hai jo aapke appliances ko kisi bhi jagah se control karne ki permission deta hai. Ye energy saving ka ek bahut hi accha
