Traditional breadboarding with 7400-series chips is valuable, but simulators like Logic.ly offer distinct advantages:

At its core, Logic.ly is a browser-based digital circuit simulator. It allows you to drag and drop components—logic gates (AND, OR, NOT, NAND, NOR, XOR, XNOR), inputs (switches, clocks), outputs (LEDs, probes), and even flip-flops or 7-segment displays in the full version—onto a canvas. You then wire them together and press “Simulate” to watch signals propagate in real time. logic.ly/demo/
