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.

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.

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?

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.

@nickshaylongmailai2717 You need t watch the video completely. The headers files must inside your coding folder. Below video may help you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EPhY_hDozeo.html

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.

All the headers must be inside the programming folder &change the blynk credentials in code as well. Below video can help you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-EPhY_hDozeo.html You can also connect to new blynk with manual credentials method.

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
@SMEDehradun
@SMEDehradun 2 года назад
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.

Why does it say BlynkEdgent.h No such file exist
@SMEDehradun
@SMEDehradun 2 года назад
There could be few reason behind it- - blynk library not properly installed, - if you are selecting proper board like NodeMCU or ESP32.

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. Blynk2 is quite different from the old one.

If you read the error that you write into the comment, then you need to replace the blynk credentials in code. And you have put all the header files inside programming code folder. Alternatively, you can do it with another method. Below is the link that can help you. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-DBrLP0DQazc.html
