Hello I need help on my project
I already read a few discussion but there is something that i cant understand
Why the value i get are not same as in my serial monitor
hope for fast response thanks
this is my coding
#define BLYNK_PRINT Serial

#include <WiFiClient.h>
#include <BlynkSimpleEsp32.h>

Please edit your post to add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:
```
Also, it’s a waste of time posting photographs of your screen. Ther information is unintelligible.
You should take screenshots with Windows Sniping tool or similar then paste them into your post.

@farisilyasa, as you’ve chosen to create an entirely new thread with correctly formatted code and screenshots rather than photographs, I’m locking this thread.
When I said:
I mean that you should use the pencil icon at the bottom of your post to edit the content:
In future please edit rather than creating a new post or a completely new topic.
For anyone who is interested, the new topic is here:
