Hello, I am working on a Quadcopter using Arduino Pro Mini 3.3v/8Mhz and I am using the code modified by an YouTube named ElectroNoob Code Available Here
but when I connect the Arduino with Multiwii GUI after uploading this code then it doesn't run but using the 5v/16Mhz variant the GUI starts to run.
Actually there are many files composing this single project.....but I can't paste that all code here otherwise it will cross the provided limit that's why I linked the website of the code....
