Hello everyone! I have been trying to create an LED cascade circuit without using the 555 or 4017 integrated circuits. The best design that seemed to work in the Falstad simulator can be seen here (uses java). Essentially it's a few NPN transistors with a base-emitter daisy chain,each with 10kOhm resistors above the reference voltage, and the LEDs in series with the collectors. When I tried that circuit in my test board, nothing seemed to get it to work. I've seen a lot of info about the aforementioned ICs, but very little that doesn't use them. Am I being silly for attempting this, or am I making it too complicated?
