Hi everyone!
As you see on the subject i have a problem in my arduino project.
This project is about a little robot that cleans and is a bluetooth-controlled via Visual Studio 2010 robot too.
And when i verified the ".ino" project, in this case the name is "Amidai_V2.5.ino", i got the next error message:
- "Amidai_V2.5.ino:75:1: error: expected initializer before 'while' Compilation error"
And i dont know what to do about it, i just start programming on arduino
NOTE : Some parts of the code are in italian...
NOTE: Some codes i copied from some pages and adapted them according to my project specifications.
Here is the code:
/* Here is the define and void sector
