After the flower-shaped three-channel running water lamp is powered on, one triode is turned on first. Due to the influence of capacitor charging, the other triode will be turned on after a delay, and the front triode is turned off. This reciprocating cycle achieves the effect of LED lights flowing water, allowing the flowing water lights to have the effect of petals flashing on the petals.
Adding more solder mask adds beauty.
