Dual DC Motor and LED Driver Circuit

@Muse - The attached schematic featured gates self-shorted on themselves (NAND with all terminals on node 2, AND on node 0), floating motors, reversed LEDs connected without current limits, and extreme simulation timing ($20\text{ s}$ gate delay, $11\text{ s}$ tran speed), resulting in an unpowered and non-functional state. This circuit provides the functional opposite: a clean, properly powered DC driver circuit that actively runs both DC motors and illuminates the indicator LED. ### Key Features - **Proper Power & Switching:** Voltage source #V1 ($3\text{ V}$) delivers power through switch #SW1 to node #drv. - **Series DC Motors:** Motors #M1 and #M2 are connected in series across the $3\text{ V}$ supply (sharing $1.5\text{ V}$ each), spinning smoothly with full transient dynamics. - **Forward-Biased Indicator:** LED #L1 is correctly oriented and paired with a current-limiting resistor to ground. - **Live Scope Monitoring:** The oscilloscope tracks the running currents through motors #M1 (blue) and #M2 (red).
