My issue? The CD4001BE provides voltage but no current (still don’t fully get how that’s possible). It couldn’t turn on my NPN. I used my last inverter so I could drive a PNP instead, now it works!

Button switches the 4 bi-color LEDs between red and green. A toggle switch enables or disables the 555 blink signal. Next is to wire the 555 to blink the 4 LEDs. It’s looking good so far. 🥳

Next up: trying to use my NOR-built AND gate to control the 555. Idea is, if I pull the signal high, the LEDs blink. If it’s low, they stay on. Hoping this lets me switch between flashing and steady with one input.

Built a working AND gate from scratch using 3 NOR gates on a CD4001 chip. Took some debugging, but it now only lights the LED when both inputs are high. Learned a ton about CMOS quirks, floating inputs, and how to tame them. Feeling good!
