Nota: I want to emphasize that the code is written by: Raj Madhuram, 2014

The error is this: ‘PixelRGB’ was not declared in this scope

I’m using Arduino 1.8.5

Thank you all

When you encounter an error you’ll see a button on the right side of the orange bar “Copy error messages”. Click that button. Paste the error in a message here USING CODE TAGS (</> button on the toolbar).

When your code requires a library that’s not included with the Arduino IDE please always post a link (using the chain link icon on the toolbar to make it clickable) to where you downloaded that library from or if you installed it using Library Manger(Sketch > Include Library > Manage Libraries) then say so and state the full name of the library.

@Dancopy, please do not hijack.

@Dancopy, please do not cross-post.
