Sequential tail lights

<< < (8/26) > >>

LukeB:
Dunno if you are into arduino at all but an arduino would make this project very very electronically simple. You can just wire one led to each pin of a small cheap arduino and learn the super basics of code to program the lights the way you want. I am also a beginner but can do a bit of arduino coding and find it much simpler.

I was meaning one of the solderless breadboards that you can experiment with.  You'll need one of those.  If you intend to get into electronics, invest in one like this with three or four lengths, rather than just a single strip (I have about 10 of this size... LOL):



Yes, you will also need a couple, what I call "proto boards", but they are often called "solderable breadboards" the same basic layout as a breadboard but meant for soldering up a permanent copy of something:



...which is what I think you meant buying a 10 pack of.

No, that won't do what you want.  I think the LM3914 is the way to go.

Try to hold off the itch to order any ICs and components yet, If I have time later today I will try to whack up an example circuit that does what you want, maybe even make a little video.

Just don't get ahead of yourself.  :)  You don't need a kit for this, you're perfectly capable of doing it yourself from scratch, plus you'll probably learn more, faster, this way than just soldering up a kit that you don't know how it works.  That will make it easier to do things like fit circuitry for brighter LEDs, etc.

Like this? Would that work?

The OP is a mechanic by trade, i think he understands parts replacement and his local laws regarding automobile servicing.  He also stated that this is for an off-road vehicle anyway.

Even if he intended road use, most jurisdictions in the USA will not hassle you if you have proper, functioning lights of the correct color and brightness, even the areas that have vehicle inspections.  (As long as you're not strobing them or something...)

Using arduinos for this is total overkill.

You can use one simple, robust analog chip to get the job done.  No programming, no crashing microcontrollers or potentially flakey digital stuff mounted in your taillight.  :)
