Ok, after changing the multisim timestep i was able to sim the circuit except for the red and yellow e/w and n/s would alternate but would completely skip the green signals. For the circuit with all red leds, I placed a multimeter on the resistor to ground, base, and collector and i got a reading of ~12.94 mA from the resistor to ground, from the output of the diodes to the base of the transistor I got ~62.44 μA, and from the source voltage to the collector I read ~9.74 mA. When i measured with the original circuit I was reading into the picoamps and microamps at the same spots. Is there a way to beef up the circuit? I tried increasing and decreasing the resistor and capacitor values and no such luck, and also I'd like to have the circuit built in multisim before I construct it so I don't blow something up.
