Steady Hand

Steady Hand (Digital Logic)

While learning about latches and flip-flops in my Introduction to Digital Logic Design course (ECE 210), I thought of a neat application of this concept: a steady hand game.

One must try to move a wire loop around a squiggly wire path without letting the two touch each other. If the wires touch, a green LED will light up indicating that the wire has been touched. By implementing an S-R latch, the green light stays on until a reset button is pressed. Thus, the circuit "remembers" its previous state, and this state can only be changed if two wires touch or the reset button is pressed.
