Dual Indicator System Powered by a Single Gear Motor!


In this video, we demonstrate a simple yet brilliant way to light up two indicators—left and right—using just the voltage from a gear motor, without any switch. This concept is both educational and creative, showing how changing voltage polarity can control LED indicators effectively.

When voltage is applied to the gear motor in one direction, one LED lights up. When the polarity is reversed, the other LED turns on. In simple terms, the direction in which the gear motor rotates determines which LED will glow—left or right.

This project doesn’t use any buttons, sensors, or extra control systems. The LEDs are directly powered by the output voltage of the gear motor, which makes the circuit minimal and very beginner-friendly.

This mechanism can be applied in toy cars, small robots, or any directional indicator system. It’s especially useful for school or college-level science projects where simplicity and innovation are key.

The components used are very basic—a DC gear motor, two LEDs, some wires, and a battery. With just these few parts, we’ve built an eye-catching and functional project that’s sure to impress.
