The serial port input end of the main control chip U1 is connected to the collector of the ultra-high frequency transistor Q1, and the second interface J2 is connected to the base of the ultra-high frequency transistor Q1. The second interface J2 is used to access the external AR GB signal and transmit the external ARGB signal to the base of the ultra-high frequency transistor Q1. The ultra-high frequency transistor Q1 is used to reversely process the external ARGB signal to obtain a serial port protocol signal, and transmit the serial port protocol signal to the main control chip U1. The main control chip U1 is used to receive the control signal and / or serial port protocol signal, and output the corresponding light string control signal to the third interface J3.

[0023] In specific implementation, an external ARGB signal can be connected through the second interface J2, and the external ARGB signal can be reversely processed through the ultra-high frequency transistor Q1 to make it conform to the specifications of the serial port protocol, thereby obtaining the corresponding serial port protocol signal, so that the main control chip U1 can use the hardware serial port transceiver protocol to parse the serial port protocol signal and transcode it into recognizable data. The control button can send a corresponding control signal to the main control chip U1, so that the main control chip U1 can determine the display effect and display color of the LED light string based on the control signal. The corresponding light string control signal is transmitted to the LED light string through the third interface J3 to realize the control of the corresponding display effect and display color of the LED light string. For example, the main control chip U1 can select the internal preset display effect and display color according to the control signal, or select the display effect and display color corresponding to the external input ARGB signal, or choose to learn the display color corresponding to the external input ARGB signal and combine it with the preset display effect to realize diversified adjustable display control of the LED light string.

In specific implementation, the mode switching button S1 can be used by the user to switch modes, so that the main control chip U1 switches the corresponding LED light string display effect and display color. When the main control chip U1 is powered on, it enters the default mode and controls the LED light string with the preset display effect and display color. When the user long-presses the mode switching button S1, it enters the transparent mode, the external ARGB signal is transmitted to the high-frequency triode through the second interface J2, and then transmitted to the main control chip U1 after signal reverse processing by the high-frequency triode Q1 for identification, and the identified data is output to the third interface J3 through the light string signal output end, realizing the transparent function. The user presses the mode switching button S1 again, and the main control chip U1 learns and saves the display color data corresponding to the ARGB signal.
