Can someone give me some ideas for a contoller for this?

Signal1 = always hot (12V DC+)
Signal2 = Brake (12V DC+)
Signal3 = Left Turn (12V DC+)
Signal4 = Right Turn (12V DC+)

0= off, 1,2,3,4,5,6,7,8 = on

No Signal=

00000000000000000000000000000000

00000000000000000000000000000000

Signal 1=

01010101010101010101010101010101

Signal 1+ Signal 2 = (flashing every .5sec)

11111111111111111111111111111111
11111111111111111111111111111111

11111111111111111111111111111111

Signal 1+ Signal 3= (.5sec delay between each set, all sets stay on until #7 is lit, then cycle starts over)

00070605040302010000000000000000
00706050403020100000000000000000

00070605040302010000000000000000

Signal 1+ Signal 4= mirror image of Signal 1+ Signal 3

Signal 1+ Signal 2 + Signal 3= ( same as Signal 1+ Signal 3, 1s flash every .5sec)

00080706050403021111111111111111

Signal 1+ Signal 2 + Signal 4= mirror image of Signal 1+ Signal 2+ Signal 3

I was looking at something like http://www.doctronics.co.uk/4017.htm or http://www.electro-tech-online.com/v...&highlight=led for the turn signal sequencing but I'm not sure it would work with 7LEDs hooked up to the same output (could I use the 4017 to trigger some kind of relay instead?), also, I would need to seperate the LEDs so that I wouldn't get crossfeed from the different signals, correct?

Maybe a microcontroller would be the best way to do it... I've flashed EEPROMS for automotive ECMs using a bin editor but that's as far as I've gone.


Thanks,

You can use microcontrollers for getting any desired sequence. The programming for that is also not very difficult.
