Does anyone know of an extremely simple circuit I can use to check if my 4017 is working?
I've been trying to build a circuit from a book with a CD4017BE IC.
First time through, the circuit did not work. It was supposed to light up 10 LEDs in sequence, at first rapidly, and then slow to a stop). In my circuit, LED 1 lit up brightly and stayed on. The other LEDs stayed off (or were imperceptibly dim).
I tried to simplify the circuit using a push button instead of a clock signal and now nothing lights up at all.
I would like to find a super-simple 9v circuit I can use to test if it is working or if it's a dud.
