Wow. Fast response. Thank you. I suspected there was a hitch. Thanks again and keep up the good work! Super helpful.
great tutorials.wish u were my microcintroller teacher. keep uploading.thank you :D
Very detailed explanation and execution happened in the first instance itself. Thanks for step by step input.
great video btw i was playing on blynk :D when video was uploaded
You are really doing great work.
very description... awesome.. thanks
Thank you for this great video!
Great job, But I didn't find the detailed instruction for different OS in the description as you said ???
for windows, select .bat file instead of .sh
Very well done! Very easy to follow step by step. It would be great if you could show the same workflow that you did for USB or wifi with a BLE DEVICE LIKE adafruit ble SHIELD. Since Blynk requires connection through a cloud or local server ,it's not clear how a ble point to point (iPhone to uno/ble sheild) would utilize a server to accomplish push notifications ...
Keep up the good work This is an impressive tool and you are helping the community greatly through education !
Notifications are not supported with BLE of course, due to the reasons you described. You would need some sort of gateway, which will collect data from your BLE devices and send it through a gateway which is connected to the internet

THANK YOU SO MUCH ANNA! YOU AWESOME
Perfettamente funzionante anche su Linux Mint.... ottimo tutorial
had some work to figure out on this in terminal but works. thanks !!
If you are good enough to go into code and find and then correct problems get in contact with me at northsidegrowthinvestmentsllc@gmail.com. We are currently stuck in neutral on a project because when trying to upload code onto microcontroller it says , error: Serial 1 is undeclared in this scope. If you can fix this issue we will pay. Thank you.
@@briansmith8250 Maybe i can help you.
@@nxbil2397 I've worked at this myself and gotten better but we still could use a real programmer. Long story made short we need to combine Linux program script/shell with Arduino c+++ program. And maybe Java. If you can help us out all these puzzle pieces together into a functional I.O.T. bot, we will gladly pay
i'm Impressed, thanks
Cute both you and your project
Hi Anna, I enjoyed very much your very interesting presentation about blynk until you started talking about "terminal". As other people on this side I was stuck at this point, because it's about iPhone and many from us have Android phones and terminal does not work as you explaned. Sorry to say but I did not find any info, how to go further. So my project failed, so Blynk UNO+USB does not work.
Thanks for tutorial
Thanks! Very handy
Great video, Anna
Thank you!
It works also with Mobilphone, i setup my nano today with a Android Mobilphone and ARDUDOID with an OTG Adapter
Thank you so much
Wow amazing!!
Amazing thanks
For somebody has questions on WINDOWS 10:
1. terminal address you have downloaded to Arduino: C:\Users\xxx\OneDrive\Documents\Arduino\libraries\Blynk\scripts
Find the" blynk-ser "icon, then right-click it, edit it, then change the proper COMM port to your Arduino's port !!!
2. Double click the blynk-ser icon to make it connect to your cellphone
ps: don't run "cmd" command to open the window, it doesn't work.
its work thanks lot
how i can work with windows after all hardware connection & programming?
Could you please upload the instruction video for Windows terminal settings???
many thanks for you
Must I write all of the text in terminal window every time i want use blynk app? some easiest way? some bat file or something like that ? I am IT lama :-)
"brew install socat"??? terminal ?? you said there will be explenation in the discription, where is it ??
would you tell me please if you find it
@@abdulhameednahhas8397 formulae.brew.sh/formula/socat
Hello! I am stuck after where you type in "marco"... whenever I click the type box, it doesnt let me type, but instead it makes me edit the terminal
whats a brew? im using windows and i did not find anything related to brew in the description, please help
I'm on windows... rather than using all the brew and socat stuff, just double click ...Documents\Arduino\libraries\Blynk\scripts\blynk-ser.bat, to set the COM port. Viola!
For Windows 10
1. Left click the windows start button.
2. Click on command prompt picture
3. Left click in the black command prompt box.
4. Type: CD C:\Users\david\Documents\Arduino\libraries\Blynk\scripts
5. Press ENTER
6. Type: blynk-ser.bat -c COM5
Use your COM Port Not Mine.
7. Press ENTER
THANKS!!!
when i've tried connecting arduino to computer successfully, then how can i control my blynk project to led arduino?
Yeah!Awesome!)
for window user which terminal are you referring to
muy bueno el video
great! Thanks:)
For Windows users I believe the parts about socat and installing it via brew are unnecessary. Instead of running blynk-ser.sh you run blynk-ser.bat which uses com2tcp instead of socat (and is included in the dir). Unfortunately, I get stuck in that script with "DSR is OFF". Not sure how to fix that.
Ah okay. leave the command prompt open. That is the last line of the output it is not an error. The app works. But I misunderstood. I want to plug my android directly in to my arduino with an OTG adapter. This ain't the code I want :( lol. Works great though.
I think it could be made clearer that what Blynk does is it allows you to use an Android device to send signals through the internet, that your PC then picks up (via the blynk-ser script) and transmits to your circuit board via a USB cable.
hey my arduino uses com 5 what should i do
Hi maam. I am new for this device i had nodemcu v3 i try many time to upload any sample of bink but error compiling board for nodemcu 1.o (esp 12 e module) can you help me?
Can you upload an example to control the arduino via esp8266?
Is it possible to control relay using blynk app and automatically at the sane time? I mean is it possible to control relay using blynk on and off button and if we want the relay to switch on or off automatically if a sensor cross a certain value?
Install scripts in windows: CMD.exe, CD to scripts, run blynk-ser.bat, choose COM port number. Keep CMD running on computer
Hi,i have some problems : how to CD to scripts? Is that use the cmd to run blynk-ser.bat？And how to choose COM port number.
Find the" blynk-ser "icon (blynk folder), then right-click it, edit it, then change the proper COMM port to your Arduino's port !!! Double click the blynk-ser icon to make it connect to your cellphone and Keep CMD running on computer
Script needs utility socat. Says to use brew to install socat. My MacOS has neither installed. Get "command not found." So what are brew and socat and how are they installed in MacOS 10.13?
What is the operating system in your computer
Can I use the blynk application without internet?
Thanks.....
very nice
Can I read sensor data as well using arduino without wifi shield?
If you're on Windows and you're lost: Just open the scripts folder on your PC normally, edit the blynk-ser.bat file to the right COM (right click>edit>save) and then just double click the blynk-ser.bat and leave it running. No need for any CMD or terminal commands really.
After having put the right COM it gives me "ERROR No such file or directory (2)" ? O_o
I have an OTG USB cable and would like to connect Arduino to my Android phone directly with the usb cable. Would that work ?
Hello Anna, I have this error in the app: it wasn't online yet, and in the CMD it does not confirm anything? I was able to load the examples on the arduino board. I have the errors in the app and in CMD. Please help. Thank you very much.
You completely lost me by 04:57 :/
my device is not showing online
So nice Queen teacher
nice job done mam
Is it possible to connect the arduino direct to the phone with otg USB cable ?
in CMD com2tcp.exe not recognize, what should i do?
Great
Can't get to make the last line of code work properly like at 5:48. I got brew to set up socut but the the ./blynk-ser.sh command returns an error. What should I do ? Thanks
check that you are in the correct directory where the script file is.
If you are still experiencing the issue, please post to community.blynk.cc
Thanks!
I have the same problem. Did you find an answer yet? Always a burden to get a link saying find it yourself. Maybe she knows the answer but is tired of answering noob questions. But shouldn't a tutorial try to bring people into some new topics? Since more people seem to struggle on the last step (!!!) Maybe she would not loose anything telling people the answer.
@@blynk ....tell Pavel to find the answer and post it here.... I couldn't find it, even if I found the link to the community BEFORE posting and asking. How hard can it be to answer a question? Those RTFM answers are inappropriate. It means FU light.....

1. When you work with hardware - there are 1 gazillion moving points, and anything can go wrong. This is why we ask to post to forum and provide details like: OS, device, hardware model, sketch you are using and so and so. We don't even know where to start with your issue... Maybe it's a broken cable, who knows?
2. It's physically impossible to answer everyone on every single channel (youtube, fb, email, insta, etc). This is why we kindly ask to post to forum, where:
- your question will be answered much quicker
- your question and answers will remain there for others experiencing same issue or having question
- it's more convenient to post detils like code snippets, etc.
Thanks for understanding.
blynk thank you for your answer.
It bothers me that I received an answer from your Pavel saying exactly the same. Problem is there is no answer on that and i still don’t get it to work.
Yes. I’m a noob. But don’t you want people to come joining you? Read the comments! I’m not the only one. You might consider helping. And posting a link where there’s no help available is if no help.
Maybe you want to make a sticky in your forum gathering what is known to solve the issue.
If Blynk is so easy why can’t I get it to work?

someone knows where is the folder that she said ? in linux please
how could i read information from arduino in my cellphone?
u r too GOOD
can u make windows tutorial please?
It is pretty much the same but you can just go to *manage libraries* or type *ctrl+shift+I* then type blynk in the search and then install it. Then restart your arduino ide. Then if you go to *examples.blynk.cc* from there you can make and copy the code and then add your wifi details and the auth token mailed to you

Some one could help me?
What output do you see in terminal after running the script?
how to open terminal in spotlight search??? anyone please respond 4:54
cmd+space
If you close your Command prompt you loose your Connection.
So make a batch file on desktop.
1. Right click and select "New Text Document" from the drop down menu.
2. Add these two lines:
CD C:\Users\david\Documents\Arduino\libraries\Blynk\scripts
blynk-ser.bat -c COM5
3. Rename the file to "Arduino USB to Internet Connection.bat"
----------------------------------------------------
Now just double click that when you need your Internet connection.
Change COM5 to your COM Port
Change david to your computer name

Did you ever get the compile problem " serial1 was not declared in this scope" fixed ? I am having the same problem and woud really like to move forward on this project.
Mother of god! She's beautiful!
how to open the terminal in windows 10
Use the search bar and look for "Command Prompt". Serial ports on windows have completely different naming conventions. It'll be COM4 or something like that.
open command prompt it is the terminal in windows
