How to Assemble Stair Lights

How to Assemble Stair Lights

Our stairs at home are used everyday at sunrise and sunset But when I return home at night, the
stairs turn into a black wall. We tried to fix this darkness problem
with the light next to the stairs, and lights above the stairs, but they weren’t good enough. I wanted
more. I looked online and instantly fell in
love with this soft start controller. But when I looked at the price, I was
heartbroken. I will show you how to build your own for
a fraction of the cost. The block diagram is incredibly simple.
At minimum, you’ll need LEDs, wires, two person detectors and control circuit. First, cut the LED strips and wires to
the appropriate length. Next, solder the LEDs to the wires and test your LEDs to make sure they
all turn on. Now you need a control circuit. If we
want all the steps to fade on or off at once, we could use something as simple as this
circuit. If we want the sequential fading for ten different steps,
component count quickly becomes a problem. For flexibility, I elected to use an Arduino. Here is how my program works: rising edges
from the motion detectors set flags. The flags are polled by a software state
machine that sets individual step’s duty cycles using the ShiftPWM library. The result is shifted to the output
stage using the hardware SPI. After this core functionality was
complete, I topped it off with daylight detection and a manual override switch. Not knowing how to use layout software let me to
painstakingly lay each component and wire on perfboard. I had
to experiment, but I found a layout that I liked and made
the connections. After a long time, I had finished a
work of art. To protect it, I sanded and painted a
project box from RadioShack to match the color of the wall. Once you test your circuit, you can begin the
final layout process. Cut and adhere any raceway you plan
to use, then lay down your lights, one at a time. Use tape or adhesive on the back of the strip.
Then, stand back and admire your handiwork. I
did this project two years ago. If I were to do it today, I would have
probably changed a few things. Now go make your own and show it off
in the comments.

  1. Would arduino mini pro work with your code and PCB?
    I was going to use BS170 to get more current for longer strips (36") 500mA vs 200

  2. Nice I wanted to do this also with an Arduino but at this point in time my programming skills a laughable at best, this is what I came up with for now, let me know what you think – Automatic Motion Activated Led Steps Stairs

  3. Hello Andrew. I'm from Germany and i'm very interesstet to build this stairlights by my own. Can you please give me a detailed instruction for building this stairlights? Or would you build one control unit for me? I will pay for your work and parts. Thank you

  4. Hey,
    I found this video quite interesting and would love to build one of my own. Should I get any circuit board, or a certain one? I'm not that knowledgable about circuits, and don't know how to read a circuit diagram, but are their certain holes i should stick the wires to? 

  5. Hola Andrew,

    Las tiras de led no se apagan en su totalidad, al apagar se quedan muy levemente encendidas, ¿sabes que puedo hacer para que apaguen por completo?

    Gracias de antemano.

  6. Can i get this project as ready mode to install in my home at India, if its ok for you kindly tell about the price details other wise the step by step creation of the aurdino board…………….

  7. hi can u send me link that how can i make this project i liked it very much please send me also source code also; give me mail id that i clear my doubt; or send me at this mail id [email protected] please send me

  8. after adding pwm to library file I just remove #include<cshift.h> header file and also time comile.h header file then it working is it correct or not tell me

  9. hey very nice project but when I try to to compell the code it says SHIFTPWM not scoped in this code ..please can you help me out here..

  10. Dear Mr Ong,
    If I want only one led strip in the hall and light this from mains. How do I do this? I have no electrical knowledge compared to you but do have a led strip, motion detectors and a tray in both my hands when I walk those stairs. What else do I need to make this simpler project work?
    Thanks in advance.

  11. This project is great but how about the Wattage of your system? Thank you for sharing this info it gives me new idea.

  12. Hi there, I have a small project to realize with me a gradual lighting of the stairs materials that I had an arduino mega. 2 motion sensor and an optocopleur card and of course I have the code mes I need your help here you want well thanks

  13. I bought excellent handbook from WoodPrix website. Just google WoodPrix and start your journey to the better life

  14. You are the only person that I could find that shows the opposite way of going down the stairs with the lights. Anybody can see them from the front view. But when you're coming up on them …Bravo for you posting that

  15. The sequential lighting of the steps add a touch of class to your project. Nice one! One thing i'm puzzled is why you would prefer to have a constant current driver for the LEDs? Wouldn't it make the wiring more complicated?

  16. This great! If more light is needed, then these lamps will work? or only LED stripe?

  17. You did a such of beautiful job can I ask you how much did you spend on all that stuff please let me know and how hard would it be to do something like this thanks
