Drag gates onto the canvas, wire them together, and toggle inputs to watch signals propagate live through your circuit.
Click an output pin (right edge, ●) then an input pin (left edge, ○) to wire them together — click either pin again to cancel. Click a wire to delete it. Click an input's switch to toggle 0/1. Drag a gate body to reposition it.
