Rotating Police Strobe Lights Effect
« on: August 30, 2017, 06:10:41 pm »
Hi!

I was wondering if there's a way to create this kind of circuit/program for my Ecto-1a build.

I see a lot of builds with flashing lights like in modern police cars, but I want to create a rotating effect.

I was thinking of using several sets of 4 LEDs per set, that do a chaser effect and create an illusion as if it's one rotating light when the 4 LEDs are grouped in a square...


Gracias!

Tenacontrols has what looks to be quite a nice kit that may work for you.

I haven't tried it out myself, but I have bought a few of their other kits and have always been satisfied with them.

Yes, and I can probably buy a built model as well.
But that's not what modelling is about.
I want to build one, not buy one :-)

But thanks for your suggestion.

I think you have answered your own question, 4 miniature SMD LEDs with a chaser program would be the way I would do it.

The issue would be wiring the 0402 LEDs!

Thanks Madmonk.

Just to write that program...
I'm new in the Arduino world :-)

I have no problem with soldering those LEDs. Already did a fiew. I love it!

The programming shouldn't be too difficult, basically all you are doing is switching on and off 4 LEDs in sequence, too assist with the illusion of rotating switch on the next LED before switching off the last, if that makes sense.

Most of the Arduino boards will be overkill for this type of functioning but its all good practice!

Yep, you can always use three or four 0603 (second smallest) or 0402 (smallest currently available) SMDs glued onto a very thin rod to simulate a law enforcement or rescue rotating beacon light.

If you want to use Arduino to control the lights, you can always use an LED chaser sketch.  There are lots of example sketeches out there, if you want to do a search for them.

I have an 8-LED Larson scanner (back-and-forth direction chaser) Arduino sketch that can be easily adapted as a continous one-direction chaser.  If you would like that sketch, let me know, and I will post it.

Thanks for the help!

Well I found a code for the Arduino for the modern "pulsating" effect that I'll use for the bar above the rotating lights in the front.

As for the rotating lights, I started working on the circuits. I'll have to make 3 independent circuits for the the 12 rotating lights (48 x 0805 SMDs in all).

Here's a short video of the first circuit. The SMDs will still be glued in place. For now they are in the "air". The second circuit will have the green SMDs.
Lots of swearing and sweating, but I'm still sane.
