Hi everyone,

I have been working a project but I have never used mit app creater. Although I am looking for something about that, I could find like this.

I want to create a text box in my app and a button. When I press the button , it must send to arduino.
Afterthat I will use data(number) to change a delay time or control LED. Something like that.

I have already tried something that it showed under the page.

 

sorry not text book it s text box

 

I haven't done this yet. I hope it helps.
