Install the Blynk Library in Arduino IDE
For the connection of the Arduino to the Blynk we need to download the library in the Arduino Intergrated Development Environment (IDE)
Steps
-
Open the application Arduino IDE:
If you don't already have it, go to the official website at https://www.arduino.cc/en/software to download and install.
-
Install the Blynk Library:
- Go to sketch then we can see the option called include library after entering the include library go to Manage libraries
- After entering the library manager search for the Blynk in the search bar
- Find the Blynk library in the list and click "Install" by Volodymyr Shymanskyy.
-
Include the Library in Your Sketch:
To require the Blynk library in the Arduino program Corrrectly, you should include it at the start of your program. It is always recommended to put the Blynk library on the initial part of your Arduino sketch since it can help you avail functions and features that will better develop the capabilities of your project.
This is easily performed by including a specific line of code from the Blynk library documentation. Taking this initial step lays the framework for easy communication between your Arduino board and the Blynk platform, allowing you to interact with a variety of digital and physical aspects in real time. To establish a robust connection between your hardware and the Blynk library, insert the code snippet carefully.
Cpp:
#include <BlynkSimpleEsp8266.h>
Thus, together with Blynk’s rich-set of tools and features available at your command-r, you can experiment, tweak and build further and cast the innovative frontier of what can be done in the field of IoT projects.
Whether you are a seasoned developer or new to the field of hardware programming, the Blynk and Arduino pair provides a friendly environment that fosters discovery and progress, allowing you to realize your most ambitious ideas.
Connect Your Arduino Board to WiFi
You might be employed on an Arduino board, with constructed-in WiFi like the ESP8266 or ESP32. If you are not using a different board then it must be slightly different from what is described above.
Connect Your Arduino to Your Computer:
Use a USB cable to connect your Arduino board to your computer.
Open a New Sketch:
In the Arduino IDE, open a new sketch by going to File and then move to new option
Configure Your WiFi Credentials:
For your sketch you will have to input your WiFi network’s name or Service Set Identifier (SSID) as well as the password.
char ssid[] = "YourNetworkSSID"; # Replace with your WiFi SSID
char pass[] = "YourNetworkPassword"; #Replace with your WiFi password
Set Up the Blynk Connection:
In the setup function of your sketch, initialize the Blynk connection using your Auth Token. Add the following code to your sketch:
char auth[] = "YourAuthToken"; #Replace with your Blynk Auth Token
void setup()
{
Serial.begin(115200);
Blynk.begin(auth, ssid, pass);
}
void loop()
{
Blynk.run();
}
Link Your Arduino to Your Blynk Project
Configure Widgets in Blynk App:
Upon installing the Blynk application, launch the project related to your Arduino and place widgets for controlling or monitoring the latter. For instance, a Button widget can be used to control an LED, allowing it to turn on and off; a Gauge widget may be used to display the reading from a sensor.
Assign Virtual Pins:
Each widget in Blynk is assigned a virtual pin. To utilize a certain virtual pin, touch on the widget and enter the pin number. For example, utilize virtual pin V1 with the Button widget.
Write Arduino Code for Widgets:
Add virtual pin handling code to your Arduino program. To operate an LED linked to digital pin 13 using a Button widget on virtual pin V1, use the following code:
#define LED_PIN 13
BLYNK_WRITE(V1)
{
int pinValue = param.asInt(); // Get value from the Blynk app
digitalWrite(LED_PIN, pinValue); // Set LED state
}
void setup()
{
Serial.begin(115200);
Blynk.begin(auth, ssid, pass);
pinMode(LED_PIN, OUTPUT);
}
void loop()
{
Blynk.run();
}
Upload the Sketch:
To upload the sketch to your Arduino board, use the Arduino IDE's "Upload" button. After the upload is complete, your Arduino should connect to the WiFi network and the Blynk server.
Unlocking the power of your Arduino device with Blynk's adaptable platform not only changes the way you interact with technology, but it also opens the door to limitless possibilities for creating interconnected, intelligent systems that improve the quality of your everyday life.
