LED STAIRS

[wdariusw]

Hello all. Just bought my own house that is under building phase. I wish to have led stairs something like this:

What is the best choise for led and MCU wiring ? Addressible led strips ? Maybe someone of this forum have done that at own house ? Sorry for bad english. Thanks !

Addressable LED strips would probably be the best choice with the use of a similar motion sensor and an MCU. Another option, depending on how many stairs, is to use non-addressable LED strips and drive them from different MCU pins. This project in both cases is very much software based and the timing effects will need to be done with coding through trial and error.

It would be cool if they would only come on when you stepped on them, the one you are on and one ahead and one behind.

There would be a lot of motion or maybe weight sensors for bigone5500 suggestion. There are lot of LED strips with individually addressible LED's , but i need one address for one LED strip. What is best solution to do that ?

Hi,

The pressure or motion sensor on each step would be a solution, it would however increase the hardware and connections. With regard to addressable LED strips, these are individually addressable so I'm not sure were your problem is. If you want an entire strip on just address all the LEDs on that strip. If cost is an issue you could mix addressable and non-addressables together, by having one addressable LED on each step and joining it to a strip of non-addressables and feeding that control signal to them but like I said this should not be necessary.

Thanks for the answer. Yes, it is solution tu turn all led strip led with same color, instead of joining one addressable led to non-addressable led strip. Or...Cheaper would be simple led strip, but more wires But my choice would be fully addressable LED strip here. Need to think about best solution with human detection. 2 sensors will be enough for me (first ar last step) . Here i'm thinking about something like that (PIR motion sensor) http://www.ebay.com/itm/1PC-HC-SR50...033323?hash=item2101051deb:g:sj4AAOSwjVVVqiSi

I think pressure sensors would be hard to install..

Unless you want different colors on the individual LEDs in a strip you are wasting your money on addressable strips. They cost a lot more than non-addressable ones.

Hello again. When i have free time, trying to do something for my stairs lighting. Here what i have did already :

I have 16 stairs, so i think that best option to choose were 16 ch PWM module. Now i thinking again about motion sensor. What is est option...i want that sensor would be as more "invisible" as it can. Can't find anything.

Picture of stairs?

 

[wdariusw]

Hello. Sorry for long delay...Here is a picture:
Still have no idea what sensor to use...PIR sensor here do not fit, because of wide angle..

Here, again

Hello again. My stairs project is under construction. We decided do stairs lighting with mechanical switch without any motion detector. Here are progress:

After 2-3 weeks stairs should be finished (without railing and LED). After about 4-5 weeks I will receive LED strips, and finish my job here !
Will post some pics here, if you are interested
