Iam new to here so please stick with me as I try.to explain my plans. Many moons ago I lit up every year but due to medical reasons gave it up for a number of years. I am better now and this is the second year that I have lit up again. I decided to invest in a raspberry pi3 model b and made some arches that I am using non addressable led lights on, the arches work yes but only with solid changing colours. I would like to get the arches chasing and have invested in a set of addressable led strip, can anyone help me to understand how to go about doing this. I also have arduino uno I am still learning.
