My 3rd big Halloween Project - an actual nightmare

Catwell
Catwell
28 Oct 2015

A little background... here are my first two Halloween projects:

The Scary Door

The Scary Porch

 

Now my third one... In this project I want to control a ton of LEDs and output sound.  Sound I have covered, from the Scary Porch project. However, the LEDs are the nightmare.

 

I am currently using shift registers to address all the LEDs in the group, working on controlling 100 LEDs right now. A shift register take 1 output and turns it into 8. It's working, but this seems like a brute force way to attack the issue.

 

Here is a test:

It is not going as seemless as I wanted. Does anyone here have some suggestions on how to control hundreds of LEDs?

    Do you want every one to be individually addressable ??, if so then neopixel (To Borrow an Adafruit brand name) will probably work best, if it is simply a few banks then perhaps a mosfet driver for each…

    Cabe, where did you bought the neopixels for this price? These are produced in China nad there are tons of producers of any kind that sell for a more reasonable price.

    I think that would be a "Nightmare before christmas" kind of project... it was meant to be scary to some extent...

     

    Back burner for sure, I guess.

    I have to ask...  not that Halloween has passed, should I even finish this project?

     

    Anyway... as for the lights. They may need to be up to 30 feet apart, around 10 meters.

     

    Let me know all your thoughts.
