Please edit your post, and add triple backticks ``` before and after your whole sketch.

4

BEFORE, and AFTER your code.

Pete.

I’ve placed “ <<< Triple Backticks HERE” where you need to put them.

Edit your post, using the pencil icon at the bottom, and replace “<<< Triple Backticks HERE” with triple backticks. If you can’t find the backtick character on your keyboard then copy/paste the ones that @John93 provided.

Pete.

10

Do you have the latest version of the blynk library (1.1.0) installed ?

11

When you’ve edited your original post and removed the “<<< Triple Backticks HERE” text that I added, I’ll post a link that explains why you are seeing this and how to fix it.

Pete.

15

done

Read this…

Pete.

Additionally, make sure that just one Blynk library is installed. Check the libraries folder. If you find multiple Blynk libraries installed, keep the most recent one and delete the others.

Sorry i did not mean any shouting its just caps lock .
i am using a 12 v 5Ah battery pack , 30 A ESC , ESP8266 and Blynk Platform .
i have connected esc cables to pin GROUND and PIN D4 for out put . The slider in the blynk is named speed with Virtual pin 2 . In the serial monitor i am able to see the change done in the slider value till yesterday but today i am not able to see any change in value of slider .

It is connected to the server but no response about the slider value .

i tried by creating a new dashboard and have the changes in the code .
The ESC beeps three time which means it is connected .
