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.

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

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.

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 .

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 .

Is not good to use capitals all the time, it comes across as SHOUTING!

Maybe you should start by sharing full information about all of the hardware you are using, and how it is connected and powered.

Pete.

Sorry. I missed that.
