Hi, I’m trying to bring data from arduino sensor to thunkable. But I have no idea what kind of value is in the data block. Please answer if you know any solution!

I’m guessing here but a byte array sounds like a list. So you may have to use the list blocks to access that data.

Hello,
Do you know how to connect an Arduino with light sensors with Thunkable, I want to control the light sensor from the app. Can you help me with that? I would really appreciate it, I really need it by today, or maximum by tomorrow.
I haven’t done the code yet, because I don’t know where to start.

Hi,
I’d recommend that you create a new topic and include as many details as possible. See this: [How to ask Great Questions v2.0](https://community.thunkable.com/t/how-to-ask-great-questions-v2-0/2689983).
This topic is three years old so I’m going to close it.
Also, if you’re in a hurry, consider paying for official support or paying someone to help you. 99% of the users on the forums are developers/customers just like you so we may not be in a hurry to answer questions when you need them.
