Can I change the color of the light emitted by an LED, changing the frequency of the voltage applied to that component? What frequency bands should I use?
No, it is not possible to change the color of the light emitted by an LED. It depends on the semiconductor material from which this component is made. Thus, even if we use signals of different frequencies, pulsating direct current, for example, the color of the light emitted by an LED does not change.
