Hi wonderful people
This is a cross-post, as I have been advised to put it in here, as the problem is now a programming one.
Its about Colorduino and error - which I have researched but found no answers that help.
avrdude: stk500_getsync(): not in sync: resp=0x00
If you could take a look I'd be most greatful - its not long.
thanks so much

Is it? If it was, you'd have posted some code. I don't see any code.
Hi thanks for your reply.
I was advised fixing the sync error mentioned in the post precedes any code errors.
Im trying to run this library and code: (1.2.4)
https://github.com/lincomatic/Colorduino/downloads
and this is the code:

I don't agree that it is a programming issue, and I think the advice from kd7eir to post it here because "there are people there that have a lot of experience with the not in sync issue" is bad advice.
Your problem is with the mechanism used to upload a sketch to your Arduino; it has nothing at all to do with the code in that sketch.
Hi PeterH
Thanks for your reply.
Do you have any advice that might help me overcome my problem?

My advice is that you ask for help in the section of the forum which is appropriate to your type of problem. That's not the Programming Questions section.
