Arduino code not working - beginner needs help

Hello,

I tried to copy this Project on GitHub ( GitHub - GitTibbe/LED-Strip-HomeKit-Driver: An RGB-LED strip driver that can be connected to a smart h ),
but I get the following error message:

The Arduino Code can't upload to my UNO.
its saying "colour" is not declared
See the following information below.

Anybody who has any idea what I can do?

thank you in advance for every hint.

You could post your code.
In code tags.

int[3] colors = [r,g,b];
int colors[3] = [r,g,b];

You can't just make up your own syntax. That never works. You have to take the time to study what is expected.

No it isn't. It is saying "color" is not declared. Spelling is important. It's easy to fall over the difference between US and UK spelling but you have to choose one and stick with it.

Hello,

since I hadnĀ“t much time I forgot this project sorry. :confused:
Thanks for the answers anyway.

I cancelled that project with that Code, because the Files have obviously too many bugs.

Hopefully i will find a better one. Hints are welcome. :slight_smile:

Kind regards
