Hello,
I am attempting to simulate a hazard light/turn signal combo with a 555 astable timer and one clocked J-K flip flop, as seen in my schematic attachment. I need them to flash at different rates, hence the 555 to create a slower waveform. I am using the slower flashing rate from the 555 to drive the turn signals.
I have both signals working independently at the slower frequency, and additionally have the hazard lights working at twice the speed of the turn signal flash. The problem is, when the hazard lights are flashing, I need the turn signal function to be disabled. Currently when the hazard lights are flashing and I turn on the turn signal, the slower waveform from the turn signal is seen in the LED output as well.
I'm sure there is some simple logic here that I'm missing, but I just can't put it together. Designer's block! Thanks so much for any help you can offer.
