In this video, we build the JK flip-flop described in my previous video (https://youtu.be/F1OC5e7Tn_o) and find out it doesn't work properly. I demonstrate "racing" (aka "race around" or "race condition") in a JK flip flop.

Complete parts list (everything in this video): - 1x 74LS02 (Quad 2-input NOR gate) - 1x 74LS11 (Triple 3-input AND gate) - 2x LEDs - 2x Momentary "Microtivity 6mm tact switch" - 3x 1KΩ resistors - 1x 100Ω resistor - 1x 0.001µF capacitor - 22 gauge wire - 5 volt power source (e.g., a USB phone charger) - Clock circuit from https://youtu.be/kRlSFm519Bo
