Brushless Motor controlling using ESC

Need Help With My Project
1

Hello,
I am using NODEMCU, ESC -30A, 930kv outrunner bldc motor,
i just need to control the speed of my motor, but it doesn’t working in that way, the motor starts beeping with some interval continuously,
Here is my code,

Blynk is a platform with iOS and Android apps to control
Arduino, Raspberry Pi and the likes over the Internet.
You can easily build graphic interfaces for all your
projects by simply dragging and dropping widgets.

This example code is in public domain.

This example runs directly on ESP8266 chip.

Note: This requires ESP8266 support package:
GitHub - esp8266/Arduino: ESP8266 core for Arduino

Please be sure to select the right ESP8266 module
in the Tools → Board menu!

Change WiFi ssid, pass, and Blynk auth token to run :slight_smile:
Feel free to apply it to any other example. It’s simple!

@Phani please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code, so that it displays correctly.
Triple backticks look like this:
```

Copy and paste these characters if you can’t find the correct character on your keyboard.

Pete.
