Heartily thanks from the bottom of the heart , new bylnk app confuses me so much atlast u taught me completely
Most welcome @Eugene Ritu
THANK YOU !! THE ONLY VIDEO that i found that shows you how to do this from start to finish !!! solved my issues - works 100% easy to setup as well thanks for the video
You are most welcome 🙏
Thank you bro for giving esp8266 programing code
🙏 thanks
Thank you so much sir, now I finally got to make it work. You sir are a lifesaver!!!!
🫡👍
@@SMEDehradun can u solve my problem ? my servo motor rotate slowly I cant sliding fast that slider button like the video , cos when i slide fast on the blynk , motor are not rotated . I using esp8266 . Can I use phone charger adapter as power source ?
@@muhdazim1729 Hi, Go to the slider setting and turn off the "send values on Release only" option. It will resolve your problem.
@@SMEDehradun I already turn off , the motor still slow to rotate
It may due to power shortage in the NodeMCU. You can use USB mobile charger for this. But be careful.
Also check the internet speed, may another cause for this issue.
Try it. If possible check the maximum angle of the motor.
U gained new subscriber from india 😊. Can u please make esp8266 rfid lock with blynk
Sure. Already in progress. Try to post as soon as possible.
Awesome explained
Thank you @NuttyEngineer.
Thank you so much...you solve my problem with servo...why you use DOUBLE not INTEGER?..thank again
In double we can also store the float values.
Sir my servo motor turns only 90 degrees when controlled in blynk, but it turns 180 degrees in sweep function. I'm using esp8266. Pls reply
K. You need to set the maximum angle limit in datastream tab. If you want to turn servo till 90, then you need to set that to 90.
Please sir, make video to control servo motor to certain position and returned back to initial position, using blynk
Hi,
You can do it by simply adding little bit commands as per your requirements.
If you want to control multiple servo motors using blynk then this video can help you.

Welcome @pro222yt
Hello Dear,
Your code is really perfect working,
But I faced another problem like Servo is Run in one way continuously!!
Can you say why is this happened??
Please give the ans ASAP!!!
Hi,
Once change the servo & then check.
well explained
Thank you
Sir, The codes in links are not for this project. Those are for LED projects. Please check them. Thank you.
Hi @Baseer
Link & codes are for servo control, & well tested & verified.
Plz check again what you have downloaded?
Sir - Thank you very much for a VERY informative video. I wish Blynk will post detailed videos like this!! I do have a question though - I'm using a WeMos D1 ESP32 board. Everything worked well as outlined in your video, up until I tried to connect the device to my Blynk app. When trying to add the device, I can connect to it on WiFi, but when choosing my home SSID, the device configures WiFi, Reconnect back to cloud, but then gets stuck on "Waiting for device online". After several minutes it gives an error message stating "Your device couldn't connect to the network". I've tried this several times, and using the Android as well as IOS devices. Any idea what the problem may be?
Hi @Johan Claassen,
Thanks for valuable comment.
There is some network issues in your wifi, either there is wrong user name or password or slow internet.
Try to connect it with other wifi or hotspot.
It may resolve your problem.
@@SMEDehradun Thank you sir. You are correct ... my mobile devices were connected to the 5GHz side of my WiFi network. I switched it to 2.4GHz and it solved the problem. Thank you again!!
Congrats. Most welcome

Sir i have the code which the code want auth id ,ssid,pass
That’s was an blynk1.0 version. It will not work with the new Blynk
i have problem when using esp8266 with servo it only rotates 90 degree instead of 180 degree
Hi,
Kindly check the maximum angles set on datastream tab in blynk web dashboard and servo motor also.
@@SMEDehradun i try it but it not working
Have you tested the servo motor? If you have alternate servo motor, then you can replace & check
@@SMEDehradun sorry i not check my servo it working at max 90°
Ohk. Great.
hi.. thank you for a very informative video.. i was wondering how to set the speed of the servo so it wont rotate so fast?

@@SMEDehradun Thank you. I'll take a look at it
sir can u help me plz i am using a ESP32 board when i followed the same process as u showed in the vide it shows me that my board is not compatible is there any way that it can be solved
Try to upload any program & let me know that your board working or not?
3:22 Is the first 180 the angle of the servo? I have a 270 degree servo motor, should I write 270 instead of 180 both times?
Yes.
you can write 270 instead of 180.
how can we add led or buzzer to be signal when its on
Simple write a command to digitally high the pin while it is on certain angle.
i have problem on i2c lcd with blynk and analog pin will you please make a video on it please
K. Can you explain what the problem you are facing on it?
i am writing code on main loop but lcd will show unknown char but blynk shows
Try to define that char as global char means define that char at the top of the program. It can work.
Do you have programming code for Stepper Motor (ESP32)? please reply asap
Yes. I will post the video on it soon.
why we didn't write any BLYNK_AUTH_TOKEN.. ?
Because you have to add your board to blynk using blynk IoT App.
If you see video carefully, will will every single steps to connect.
Sir plz help me I have esp8266 it not working
Hi,
Plz watch the complete video. I have shown all the steps.
Sit then which id we will write in the place of auth id
You need to add the blynk credentials in the program from the blynk template. Se the video properly & follow all the steps. I have shown all the steps in the video
Which id we want to add in auth id
Plz check the video properly. This is the Only way you can go with blynk2
Where did you gave the wifi details to the nodemcu?
I haven't noticed in the entire video an I'm unable to controll it with esp8266
Hello Sai Ram,
This is new Blynk2.0 IoT version. It is elite different from the blynk legacy version.
You just need to connect your NodeMCU or ESP32 board to wifi through the new Blynk IoT app.
If you watch the full video, you will understand how we connect it & there is no alternate for it.
@@SMEDehradun I have finally got the controll over servi motor successfully, but sir its only rotating 90 degrees in both clockwise and anti clockwise. But I want it to move 180 degrees. Can u please help me. Is there anything to change in the code?
Tomorrow i have to submit this project in my college.
It can b due to maximum value set to 90 in datastream or may be servo maximum angles are 90 degree.
Check both conditions.
My servo model name is sg90.
I don't know about the servo motor max angles. But I kept the value in the datastreem as 180 degrees only.
Sg90 comes is variant- 90, 180, 360. So it may be.
i can't connect to wifi in Blynk can you help me ? I'm using Esp8266. I compile not error.
Yes.
What’s the error you are getting while connecting to blynk.
@@SMEDehradun When I load the code into esp8266, this led goes off. I can't find Wifi esp8266. But I try to download the code to run Servo not connecting to Blynk it works
Ohk.
So you need to erase the eeprom of your Board then try again.

Sir, I use NodeMCU ESP8266 V.3 I follow you every step but, I can’t connect device with my phone. Can you please help me is there something that I can check?
Have you uploaded the code to your NodeMCU?
If possible install the blynk to other Mobile. Some time, android do not support the Blynk2.
@@SMEDehradun I have no problem connect to my phone by using this czcams.com/video/AvSCAxbqvvE/video.html but, I really need to use servo for my project and I found out that you channel is very useful So, I try to study about code that you wrote.
Now, the only problem is conect to my phone because when I upload code my servo move a little bit.
Follow the instruction as shown in the video. It will work.
@@PeerawatSornphao thanks.
Sir I need help..
I am using esp8266 and everything is going good but the servo motor is not rotating.. I hope I get a solution for this
Hi,
Plz check what you have feed the minimum & maximum value you have to virtual pin that control the servo.
And also check the servo maximum rotation angle.
This will help you to resolve the problem.
@@SMEDehradun I have given 0 to 180 sir
Then check your servo motor.
@@SMEDehradun sir. I changed the servo motor ... Now it's working .

How can we control a normal dc motor with nodemcu?
You can use L293D motor driver for it. It’s very easy.
@@SMEDehradun but how to do its wiring
Check the circuit diagram. You can download it from the video description.
My servo motor is rotating only 90 degree even after setting it at 180 degrees it is capable to rotate 180 but still it is rotating 90 degrees
It can be due to power issue. Provide 5V DC power to servo without any load. And also check the blynk slider values.
I have a Tower Pro SG-90 servo motor. I tried replacing attach(D2) with attach(D4,544,2400) and it solved my issue. We're setting the minimum and maximum pulse widths. I think those values may change for different servo motors.

how to control servo motor more than one
Hi,
You need to add code for second servo in the program
@@SMEDehradun can you share with me coding to control more than servo
Mail me your requirement at schematicslab@gmail.com
Why does it say BlynkEdgent.h No such file exist
There could be few reason behind it-
- blynk library not properly installed,
- if you are selecting proper board like NodeMCU or ESP32.
@@SMEDehradun I encountered another problem it says that In included file: typedef redefinition with different types ('int' vs '_ssize_t' (aka 'long long'))
Hi,
Plz follow all the instructions as shown in the video. Other wise you may miss the things.
And if you were using old blynk then remove that library. And use the latest or as shown in the video.
