Blynk with NodeMCU ESP8266- Web dashboard and Mobile App

In this video lesson, we’ll learn how to use the new Blynk with NodeMCU ESP8266. This step-by-step tutorial will walk you through the process of creating a template in the Blynk IoT Cloud Platform and write Arduino code for the ESP8266 Microcontroller. Later on, we’ll create a mobile app. Also, we will explore how to set up WiFi credentials so that NodeMCU ESP8266 will connect to Blynk Cloud. In the end, we’ll control LED connected to GPIO2 using Blynk Web dashboard as well as from Mobile App.
The Project will Break down into the Following Steps:
STEP 1 Create Blynk account blynk.cloud/dashboard/register
STEP 2 Install latest Blynk libraries into Arduino IDE
STEP 3 Write Arduino sketch to control Pin of an ESP8266
STEP 4 Install Blynk IoT App in Mobile Phone, Android, and iOS
STEP 5 Click "Add new device" and configure WiFi on ESP8266
STEP 6 Create a Mobile App with a button to Control LED

It really helped me a lot, especially because I'm a beginner in arduino and there are not so many tutorials yet showing how to work around the new blynk app. I hope you have a great day, weekend, month, year and forever wherever you are I'm so excited right now!!!

The App allows the configuration of the Wifi Network, user and password, however, in the last step, it exceeds the time and does not enable the card to be used on the network. Do you have any more tips? Grateful.

    Hi Eri, LED is connected at D4 which is GPIO2 Pin on NodeMCU ESP8266. So you must connect longer leg of LED means anode to D4 Pin and shorter leg of LED means cathode to connect to GND Pin. As far as Arduino Mega2560 concern I suggest consider using Arduino IOT Cloud platform as well if in case Blynk doesn't support Mega series of Arduino Board. I hope this may help you. Good luck!

    Hi Gnanasekhar, its because in Arduino code for Blynk we used baud rate 115200. That's the reason, we have to set Arduino Serial monitor to 115200 while reading data. When it comes to ESP32, it doesn't change much except choosing correct device while creating blynk template in Blynk Dashboard while creation. I hope this may help you. Good luck and best wishes!

Once Its configured and NodeMCU connected to Blynk IoT over internet then you can move anywhere with your mobile phone. You still can control remotely your devices at home 2000+ km away from your same mobile phone and Blynk App. I hope this answers your questions. Thanking you!

But all I can say is Virtual Pin is a concept from Blynk IoT platform which will let you control any analog or digital pin of microcontroller like ESP8266 or ESP82 etc. Now to control solenoid valve you can use virtual pin as i've used in this example project. Check my relay control video lesson as well to get idea how we can easily replace LED and instead control high voltage devices. I hope this may help you. Good luck and Best wishes for your project!

    Umesh, Can you please explain how you get this sketch to work when you don't uncomment "#define USE_NODE_MCU_BOARD" I have had a lot of issues getting the esp8266 to communicate with Blynk and through the troubleshooting and assistance from Blynk I narrowed the problem down to this 1 line of code. What is really weird, when left commented, the sketch works. When un-commented, i.e. telling Arduino which board is being used, the sketch does not work. This lets me think that you are defining the board somewhere else.

    When I go to connect my device to the app at 18:39 .It searches and finds my device and I put all my network info in and it tries to connect though it always fails. Anyone else having this issue? I can not find a solution at all. I do wonder if it has to do with the part in code that says, "uncomment your board or configure in settings" In the video he has that same bit of code that he never changed. My board settings are correct as far as I can tell. I am just lost, would appreciate any tips at all! Thank you all

    Hi there, First and foremost, very detailed manual, congrats. Sadly, it does not work to me. The thorny matter is the connection between mobile application and the NodeMCU. As you have in minute 18:53 in your video, I see the wifi broadcast by my NodeMCU thanks to the previous uploaded Adgent_ESP8266. However, once I click on the wifi (Blynk NodeMCU-0A131 in my case) nothing happens. So, no way to transfer to the NodeMCU the wifi and password to be connected to. On top of that, once I open the mobile application and I log in, I get a message that does not appear in your case: "Now go to your computer. Check your inbox for the code and instructions on how to get your device online" . The question is what on earth inbox is the application talking about? I went on my blynk online profile and there is not inbox!! Neither in my email inbox. Programmers.... :-) I guess that there is something new in the last version of the app for Android. By the way, I am using blynk IoT 1.5.3 on Android. Thanks

    Well, after being fighting for a while, I could make it work. I would like to clarify some tricky things from this good video tutorial to make it more solid: 1) At minute 10:22. The file BlynkEdgent.h available on Gighub (see author video description) must be downloaded. Then the code of this file must be copied. After that, go to Arduino IDE: File-->Examples-->Blynk-->Blynk.Edgent-->Edgent_ESP8266. Then erase the code of the Edgent_ESP8266 (don't be worried, the file is protected and it can be only read) then, paste the code of the file BlynkEdgent.h from Gighub in the Edgent_ESP8266 file. Finally, copy and past the parameters BLYNK_TEMPLATE_ID and BLYNK_DEVICE_NAME according to your project. Then, upload the file to your NodeMCU. Open a serial monitor from IDE (tools-->serial monitor), press reset and if everything is OK you should have something similar to this: AP SSID: Blynk TEST-546K6 [6464] AP IP: 192.168.4.1 [6465] AP URL: blynk.setup [34666] WAIT_CONFIG => CONFIGURING IMPORTANT: if you try to run the file from Gighub (BlynkEdgent.h) stand alone the compilation will crash due to the lack of concordance with the paths of extra files/functions which are needed for the compilation: "BlynkEdgent.h: No such file or directory". 2) At minute 18:17. First, your mobile phone must be connected to the wifi provided by the access point router or whatsoever where you want to connect the NodeMCU. After the point 1 explained before, the NodeMCU is broadcasting a wifi with a name similar to "Blynk XXXX" . Well, if for some reason your mobile has connected to this NodeMCU wifi in some how before completing the process explain in the video, you have to go to your mobile configuration and select "forget this network". Otherwise the process of transferring the wifi password to the NodeMCU will crash. Moreover, if something wrong happens during the process of transferring the password and the wifi name by Blynk mobile app, before repeat the process you have to go to your mobile configuration check the saved networks, choose the one called "Blynk XXXX" and select "forget this network". 3) At minute 22:37 .The so called pin V0 is mapped in the NodeMCU board as pin D4. This is not trivial and is briefly commented in the video. A full mapping of the ports and their correspondence according to the Pin DataStearms on Blynk online application will be very welcome. 4) At minute 22:40. Whatever LED must be connected in series with a resistor (150ohms is fine) to limit the current through. I hope these descriptions are useful and suitable to improve this great video manual. Thanks
