@Wan_Syazwan 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:
```
Pete.
done
You’ve edited the code, but added the wrong characters at the beginning and end of your code, despite me providing you with triple backticks that you can copy/paste.
Please try again.
Pete.
You should read this…
You also have some strange and misleading statements in your comments…
Your board doesn’t run multiple code threads simultaneously. The cradle function executes fully before the Blynk.run command is executed, not during the for loop within the cradle function.
Also, what is the purpose of this line of code…
Pete.
Sorry, your multiwifi tag made me think that you were using an ESP8266 as your main board, not an Arduino, but I see from the included libraries this isn’t the case.
It is always a good idea to provide the information that is requested when you first create the topic.
Pete.
so my code right or not ?
No, as I said before.
Pete.
What’s wrong with my code can you tell me clearly
Have you read and understood the ‘keep your void loop clean’ document?
Pete.
