At this time, because the second stationary and second moving terminals of the first push-button switch S1 are conducting, and the eighth and ninth terminals of the first analog switch IC3 are conducting, the first control signal triggers the first power transistor Q1 and the second power transistor Q2 to conduct, causing the first LED module 5 and the second LED module 6 to light up simultaneously and blink together. When it is necessary for the first LED module 5 and the second LED module 6 to blink individually... The first button switch S1 is closed, and the third and fourth terminals of the first analog switch IC3 are turned on. The first control signal turns on the first power transistor Q1, and the second control signal turns on the second switch V2, causing the second power transistor Q2 to turn on. This causes the first LED and the second LED to blink alternately. If it is necessary for the first LED and the second LED to maintain a constant value, the second button switch S2 is pressed, causing the third and fourth terminals of the second analog switch IC4 to turn on, and the eighth and ninth terminals of the second analog switch IC4 to turn on. This causes the first control signal output by the first controller IC2 to simultaneously trigger the first power transistor Q1 and the second power transistor Q2 to turn on, controlling the first LED and the second LED to illuminate. The second control signal output by the controller IC2 simultaneously triggers the first switch V1 and the second switch V2 to turn on, triggering the first power transistor Q1 and the second power transistor Q2 to turn on, controlling the first LED and the second LED to illuminate.
