Hello all.
I am interested in creating a sequential led turn signal. I have scoured the web for schematics and I located one HERE. It looks legit to me so I built it and of course it doesn't work for me. I have checked and re-checked the connections and they are all correct.
The LED at D1 which signals proper operation of the 555 timer is blinking like it should and adjusting the 100k pot makes it go faster and slower as expected. I cant get the 4094 to sequence through its outputs, it just turns them all on and they blink somewhat in sync with the 555. If I connect the switch wire, they go all go solid at once, not in sequence like they should.
I guess my question is, is the 4094 actually suitable for this concept or would I be better off with a decade counter like the 4017.
Maybe I am using the 4094 wrong...I made a separate PWM to serve as a "clock" for input to the 4094, put pins 1, 2, 15 and 16 to 12v (Strobe, Data, OE, Vcc) and pin 3 to pin 3 of the 555 (555 Clock Out to 4094 Clock In) and the 4094 just heats up and puts 12v to all the outputs.
I also am curious about the operation of the FET Amp at Q1, I think it is being used as a switch of some sort when 12v is applied to the second input but I don't know enough about transistors to assume that's accurate.
Please tell me, why do I fail? LoL
