AVR-Chat

Sorry :(     http://img214.imageshack.us/img214/2977/allcircuitscopycopy.png
 
 
a) The hexagon simply represents the third power source which when on will turn both led's on at half brightness.
 
b) The arrows represent the power source to flash the appropriate led on full and off
 
c) When power is applied to the "hexagon" AND to one of the arrows that led will alternate between full brightnes and half brightness, while the other led will stay on at half brightness.
 
 
Maybe this would be easier with 2-12V relays, if I can find a place to stick them.

Hmmm -

Not quite.

Get rid of the two diodes next to the 470 ohm resistors.

Add one more diode to the resistor common point

Get rid of the red hexagon

One diode to yellow arrow
Other diode to other yellow arrow.
