We only guarantee that the products are in good condition before delivery, and cannot guarantee 100% success after installation. The installation of the circuit requires the buyer to have experience in the circuit, please read the product description carefully before payment.
Circuit function: 32 LED combinations flicker and emit multi state cyclic light, and the "heart tip" LED is in standby mode after S1 is turned off.
Circuit principle: The core component of the circuit is a new type of microcontroller, which uses 8 10 pins to control 32 LEDs to flash and light up according to the program settings. S1 is the start stop switch, and the circuit defaults to the working state after being powered on. The program works in multiple ways, such as full on - full off flashing, flowing water flashing, stack flashing, contracting flashing on both sides, rotating flashing, and so on. Whenever S1 is pressed, the circuit enters standby mode, and the "heart tip" LED flashes in a breathing state. Press S1 again to enter working mode.
Installation precautions: All components should be installed tightly against the surface of the circuit board, and attention should be paid to the polarity direction of the integrated circuit and LED. The power supply voltage can be between 3-5 V DC. The higher the voltage, the brighter the LED.
