LED strip - moving light for outside

Projects General Guidance
1

Hi folks,

I'm totally new to this and probably what you would call a newbie or greenhorn.
However, to get to know arduino and the way of programming, I learn the best if I actually use it for a project that I want to complete.

Is therefore someone able to point me to the correct tutorial for this?
I want to create a moving light with an LED strip outside our house, which will be a guiding light to the main door. Basically once a PIR sensor is triggered on one side, the leds should go on one by one. The same the other way around (when you leave the house).
I've seen similar tutorials and I think this won't be rocket science, but it would be great if someone can point me into the right direction...so I can see if this actually does work and I'm not going down the wrong road.

Thanks
billyray

Why have you posted your question in the Introductory Tutorials section where it clearly says
PLEASE DON'T POST YOUR QUESTIONS IN THIS TUTORIAL SECTION

Apologies, please remove. I will post it in a different section.

I think we need to know which LED strip, PIR sensor and Arduino that you are using.

This link sounds like it will give you info;

There is also an existing topic that probably covers a lot of what you need to know.

The easiest (albeit not cheapest) will be a strip with individually addressable lights - look for the WS2812 based ones, they're well supported by Arduino.

Otherwise you'll at the very least need to know how many LEDs you plan on using, and how you plan to wire them (you'll have to use a grid so you have enough pins available, but still you're going to need lots of wires running in parallel to your LED strip).
