So I've made a version of the LED sequencer from Kitt (the car from Night Rider) using a 74154 decoder hooked up to a counter and a flip-flop. Everything works fine, but my teacher said it's not very authentic because the LEDs don't fade out. I figuered it was an easy fix as all I needed to do was add a capacitor
The problem is, I can't figure out how I need to be connecting the capacitor. Here's how I *think* it should work:
The resistor used is a 1kΩ and the cap is a 47µF
The problem is, that doesn't work...I know I'm missing something here, but I just can't figure it out.
