Plz tell me the conclusion of Dancing light circuit.

LED (light emitting diode) is a semiconductor light-emitting diode. We know that the diode currently allows one direction and does not allow the reverse current which will affect the components in the circuit. The LED also does the same thing, but it emits a small light, when it allows the current, which is working on the circuit, will signal or visual signals to the normal human. There are a lot of apps using LID. They are mainly used for visual signals in any electronic device, measuring process and talking, showing pictures in TV or any ad archives etc.
