give me trick about arduino for IOT,
What?
I use nodemcu. That's not an Arduino though, although it's programmable via the Arduino IDE.
Can I suggest you read the 'How to use the Forum' post, see link below.

Most people will probable ignore a post with a meaningless title like 'Trick' so you wont get a lot of help.
And also a good idea to explain what it is you actually want to do and also explain what you mean by 'trick' ?

Put an Arduino under a hat.
Hit the hat with a hammer many times.
Remove the Arduino from the hat totally undamaged.

Preferably while wearing the hat

Good trick, is that with a clone or genuine Arduino?
What model Arduino?
Can you post your code for that between code tags
Can you please post a copy of your circuit, in CAD or a picture of a hand drawn circuit in jpg, png?
Thanks.. Tom..
My crystal ball tells me that this trick can be performed with the Pico Pro model, which is due for release in 2142 by the Sirius Cybernetics Corporation. It for sure is not a clone, after all, the company owns everything digital so there are no more clones to worry about. Unfortunately there no circuit diagrams available, as they bought up Fritzing and subsequently EOLed our favourite circuit drawing software.
The Fritzing brand however lives on in the form of colourful spaghetti, a favourite among children and adults alike. At least by then we don't have to rely on single-coloured Soylent products any more, so I see that as a major step forward.
Preferably while wearing the hat
Magician preparing trick: As you can see, the hat is completely empty.
My friends say even when im wearing the hat, it’s completely empty.

Isn't that a Raspberry Pi thing though 
I guess that would be a good trick.
Sure, just that it would give a big soggy mess after hitting it.

Is that "SKYNET"?
If it is "I'll be baaaacchhhh"

So you are a com-poseur ?
Or someone on the fiddle ?
Or whiling away the time with your organ ?

No I'm a "corn-posor"
