Claim 16:
17. The method of claim 11, further comprising:
providing another addressable LED group having a plurality of ARGB LED units which are connected in series and controlled serially by another specific sequence of digital signals to display colors;
providing another input interface circuit to sense a user's another control state;
providing another control circuit coupled to the another addressable LED group and the another input interface circuit; and
providing another specific signal port of the processing circuit, coupled to the another addressable LED group and coupled to the another input interface circuit through the another control circuit, and using the another specific signal port to receive the another specific sequence of digital signals and then transmit the another specific sequence of digital signals into an input of another first addressable LED unit in the another addressable LED group in the addressable RGB mode and to receive another output control signal generated from the another input interface circuit by sensing the user's another control state in the input control mode.
