. Now head over to the Blynk examples site and make your selection as per what you chose in the app to generate the code and upload to your device. Add your Auth Token to complete the code.Step 2

• Blynk Libraries are to be installed manually. Download the latest release.zip file from Github.
• Unzip this file and copy all contents to the Libraries folder of the Arduino IDE.

Step 3

• Devices need to talk to Blynk Cloud to run the instructions.
• Create a new Sketch and paste the example code to write to the device. Ensure the Device, its connection type is selected appropriately.

Check your Board, Connection and the COM port

4. In our example using USB as the connection type, you will need to ensure the device is able to connect to the Blynk Cloud by running a server script.

5. For Windows users, you can run the blynk-ser.bat with the correct COM port as per the instruction here.

6. Once the script is ready, you can now run the project by clicking on the play icon.

7. You will now see the message that the project is connected and that your device is now ready.8. Once the project is running, the switch label is changed to OFF. Tap the button to see the LED turning ON and OFF every time you change its state.

Congratulations on completing your first project. This is the simplest project I could think to encourage beginners to start using with what minimum they have — Arduino+Blynk.Happy to get your comments to write more on such topics.
