Making a set of LED's flash a certain way using a PCB
I am working with my brother-in-law to modify his car so that he can have a
set of amber LED is flashing in his back window the same way police car
caution lights do. We are starting from scratch so this is going to
be an interesting project. I am looking for any suggestions, or help
that someone more experienced in circuit building can provide. What we
wanna do is create a circuit (or multiple circuits) that can make 8 LED is
flash in these sequences. (they flash in order of the numbers) 1 -- 2 -- 3 -- 4 -- 4 -- 3 -- 2 -- 1 1 -- 2 -- 3 -- 4 -- 5 -- 6 -- 7 -- 8 8 -- 7 -- 6 -- 5 -- 4 -- 3 -- 2 -- 1 1 -- x -- 2 -- x -- x -- 2 -- x -- 1 . i honestly have no clue how I'd get them to blink in that sequence at a pace quick enough to make them effective... if anyone can give me instructions on how to make such a board(s), tips, or references to electronic devices / boards that already do this (flash in that sequence, NOT already assembled bar lights) I'd be grateful...
Alfredo,
I've been thinking about doing the exact same thing on the back of my van
but also having the lights function as brake & turn indicators as well.
My approach would be to use a small microprocessor to control the lights
(since this is something that I do as both hobby & work). years ago I
built a number of displays that had different circuits of lights that would run sequences, all built around logic gates since processors were expensive at the time. Guessing that you have no experience in programming microprocessors, I would suggest that you look into a product called ''the basic stamp''. It is a small processor that you program in a computer dialect called ''basic'' (an easy to learn computer language).
