Blynk.begin(Authorization_key,SSID,Password) loop() function Through correct credentials, a successful connection will be made. All three of these were defined earlier on in the program code.

ARDUINO IDEA FOR PROJECT PASSWORD

The second is the SSID and the third parameter is the password of the WIFI. Now, we will connect our ESP32 module with the Blynk app by using the Blynk.begin() function. The arguments will be the SSID and the password which we defined earlier in the code.

The following section of code will connect our ESP32 board with the local network whose network credentials we already specified above. Thus, we will control this pin through the app. Make sure to enter the same GPIO pin in the program code which you saved when creating the button in the Blynk app. It will save the GPIO pin through which we will connect our LED. Then, we will define the variable of data type int called ‘led_gpio’. We will also include the libraries, for the Blynk application functionality. WiFi.h will help in establishing the connection between the ESP32 module to a wireless network. } How the Code Works? Including Librariesįirstly, we will include the necessary libraries required for this project. #define Password '********' //replace with your passwordīlynk.begin(Authorization_key,SSID,Password) #define SSID 'Write_your_SSID_here' // replace with your SSID #define Authorization_key 'hXBwHPyX-kvDSQAxkEq_R_A21x******' Additionally, you also have to provide your Authorization key which you obtained from the Blynk app.

You need to enter your network credentials. Open your Arduino IDE and go to File > New to open a new file. Arduino Sketch (Connecting ESP32 with Blynk) After installation of the library, restart your IDE. zip Library inside the IDE to add the library as well. You have to go to Sketch > Include Library > Add. We will require the following components for this project. Our aim is to control outputs so we will use an LED for simplicity and ease of use. We will control a single LED output through the Blynk mobile application. Thus, building your IoT projects through Blynk is extremely easy and requires very little effort. You only need to drag and place your electronic components and it is as easy as that. No internal programming is required to build your project in Blynk. You can control LEDs, relays, electric motors and many more.

This will as a result create a mobile app through which the user will be able to control microcontrollers connected through WIFI. It provides an interactive dashboard where the user can build their own IoT projects by placing components.

Controlling LED using ESP32, Arduino IDE and Blynk application.īlynk is a highly accessible smartphone-based application available for both Android and iOS operating systems.

Installing the Blynk app and creating our project.

This article is divided into these sub-topics: We can also control the buzzer, relay, motors, etc. After that controlling any other ESP32 module’s output will be relatively easy to follow. The LED will be toggled through two-way communication between the ESP32 board and the Blynk project which you will create through the application. For this article, we will keep it simple and control an LED connected to an output GPIO of our ESP32 module through the app in Arduino IDE.
