sequencing sets of leds

[deth4ub4me]

I have 5 sets of led lights each containing 16 leds and would like to make a traffic director circuit with 4 switchs. One to flash them left to right, one right to left, one from center out and one all flashing. I have seen chasers, sequencers and flasher circuits but not anything for this type. Will be operated on 13.5v, each set of leds draws approximately 135ma. Any help will be greatly appreciated.

Sounds like your in need of a simple PIC program!

Thank you, I have been wondering about a pic but have not used any before. I like the idea of them but am unsure about programming options. Do you know of any good hardware/software for programming them.

a timer and 4017 IC with few transistors can do the job, when you say left to right and right to left etc its the same sequence but the location of the LEDs are reversed.

I use Swordfish PIC Basic, though the approach is much the same with any form of PIC Basic

I made a quick article for the LED program, it has the source code and links for Swordfish library files.

start 1 2 3 4 5 end, start 5 4 3 2 1 end, start 3 24 15 end, and start 12345 end. I would like the circuit to have a push button for each sequence.
