Implementing a custom opto-coupled potentiometer requires minimal components - simply pair two photoresistors in series with their midpoint serving as the common tap. Next, utilize two PWM-controlled LEDs to energize them and voila! You'll have a functional equivalent of a traditional potentiometer that can be effortlessly controlled by an Arduino board.
