In some cases they are also animated electronically. An electronic Christmas light comprises of a resistor based voltage divider, a filter capacitor and a fixed program microcontroller The animation modes can be changed with the help of a button. The micriocontroller possesses three or four outputs that are either connected to the transistor or to the thyristors. The interleaved strings that are red, blue green and yellow in color are controlled by the thyristors or the transistor to which the outputs of the microcontroller is connected. With the help of a rotating color filter disc Fiber-optic Christmas trees can be electronically animated only when an incandescent light is used. Electronic animation is being used with LED-base fiber optics since 2005.
Not only, the homes but the Christmas trees are also decorated with these animated lights.
