LED Blink With ESP32 and Blynk

Controlled LED using ESP32 with Blynk App


In this Project, We Will Build A Small Home Automation System using ESP32 And the Blynk App. we will use the Arduino IDE Software for programming. we control the home applications wirelessly.

Also, we show how to control the LED over the internet using the Blynk application. so we make this tutorial the basis for the projects I will create more projects in future.

Just flow the Blog and Install ESP32 Driver in Arduino Ide

this tutorial is very used in future projects. just flow the blog and do step by step.

ESP32 Module








ESP32 Board

In this Project, we Used The ESP32 Board so many GPIO Pins are Available to connect to multiple Systems.

ESP32 Baord


  • Includes Chip is CP2102 USB-UART Bridge
  • IS operating Power Supply is 5v
  • IS also Supported three Modes Ap, STA and AP+STA
  • IS Also Supports the RTOS


LED (Light-Emitting Diode)

Image Reference

  • is 2 pin Anode(+) and Cathode(-)
  • is operating voltage is 1.5v to 3v

Circuit Diagram

We just connected the led to ESP32 Pin Number Is 33,26,14 And 13

Source Code

Blynk Library — Download

Before You upload the Code You Just Change The Auth token and Wifi Credentials

Blynk App Setup

What is the Blynk App???

Blynk App is a simple and open-source IoT Platform for iOS and Android devices. you just customized the dashboard to your so many widgets available Like Buttons, Display, Sliders and LED?

We just control the LED Light remotely ON and OFF over the internet using the ESP32 Board, we will just show a simple example of how to use the New Blynk app Platform. so this blog will help in future to create so many projects.

Blynk App


  • Now when you log in the Blynk And just create the new Templates


  • Just Select the Proper Board In this Project we used the ESP32 Board That’s why I selected the ESP32 Board With Wi-Fi.

Demo Of Projects

Now We just turn on the application and just turn on And Turn off The Switch

Screenshot 2022 12 24 at 11.46.29 PM

We just click the Switch1 And you see the Led Will Turn On

Screenshot 2022 12 24 at 11.46.40 PM

We Click the Switch2 the second LED Will be ON
