[0002] Circuits, the foundation of electronics and electrical engineering, play a vital role in a wide range of devices and systems. Learning about circuits can stimulate students' interest in science and cultivate their hands-on skills and innovative thinking. Existing demonstration devices feature a teaching board with several segments of LED lights acting as light-emitting circuit conductors connected to a power source. Each segment of the light-emitting circuit conductor is interconnected via terminals via momentary switches, acting as control elements, to achieve segmented control. Incandescent lamps and resistors are also installed on the light-emitting circuit conductors.

[0003] Existing demonstration devices require the audience to manually operate the momentary switch to light up the LED light strips of the corresponding luminous circuit conductors step by step. The circuits need to be manually connected and controlled during the demonstration. This is not suitable for high-frequency demonstrations in science and technology museums. It is difficult for young audiences to operate and there are certain electrical safety hazards. Existing demonstration devices use LED light strips as luminous circuit conductors, which have problems such as LED lamp burnout and damage, brightness and light color attenuation, etc., which affect the display effect.
