Hi all, first post here.
I simulated a counter activated by a switch on falstad : starting with all LEDs off, then LEDs ON one at a time, 1. first LED on, 2. second LED on, 3. third LED on, then 4. button push turns LEDs off (reset). Here is the link to that simulation : https://tinyurl.com/y7cexevw
The problem I am having is recreating it on a breadboard. I have attached my work down below. Used on the breadboard are 2 JK flip-flops (XD74LS76) and 1 AND gate (XD74LS08). I am using 9V battery on breadboard. In simulation I used 5V (Not sure if that matters).
I am no expert in JK flip flops or counters, and pretty new to simulating / building as a whole, so I am eager to learn what I am doing wrong here.
Thanks for the input.
