Story

Hello, in this tutoiral I am going to show how to create your own IoT-based project. Let's get started....

Step 1:

Upload the program given below to your ESP-01 (change your ssid and password of your wifi in code.) with the help of arduino Uno I had already show the steps for uploading the code in the Uno so it can make communication with the ESP-01 module.

Install blynk library to your IDE please watch the Video

Step 2:

The connections are similar as my previous project you just need to connect the led with the help of 1K resistor (make sure resistor is connected to anode of led).

Connections for LED

Step 3:

Install Blynk app from play store or apple store.

Step 4:

Follow the steps in the video carefully.

Now you are done you can turn on or off led with the help of blynk app from anywhere in the world!!!

Code

Blynk LED code

#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "6e99585c592b4532ab7bff70ba2c15b2";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "pratik";
char pass[] = "123456798";

void setup()
{
  // Debug console
  Serial.begin(9600);

  Blynk.begin(auth, ssid, pass);
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 80);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8080);
}

void loop()
{
  Blynk.run();
 
}
