The circuit uses sound to control 11 LED flowing water to emit light, which is suitable for assembly practice, skill training, assembly competition, etc. This kit can display the functions of CD4017 very intuitively, and is a kit for learning counters, frequency dividers, and lantern controllers. At the same time, the kit has good effects, is very interesting and practical, and is also the preferred material for beginners to get started. The circuit board is glass fiber board Circuit function: 10 LEDs light up in turn according to the sound volume and level of the flowing water. The louder the sound, the faster the water flowing. The L11 flashes once per cycle, which can visually display the functions of the 4017. Working voltage: 4V--12V, the higher the voltage, the brighter the LED will be. Circuit principle: Q1 and its peripheral circuits form a simple amplifier circuit, the MIC converts the sound signal into an electrical signal, and is coupled to Q1 through C3 for amplification, and a voltage signal with high and low changes is formed at the collector of Q1, and a voltage with sufficient amplitude is sent to the CD4017. Counting input terminal (pin 14), every time a pulse arrives, the high level output by Q0-9 of the counter moves 1 bit in turn, lighting up the corresponding LED, thus producing the feeling of running water. Among them, L11 is connected to the counting output terminal CO of 4017. When L1-5 is lit, the CO terminal of 4017 outputs a high level, and L11 is lit. When L6-10 is lit, the CO terminal outputs a low level, and L11 is not lit. If you feel that L11 is unsightly, you can also not install it, and it will not affect the circuit work at all.
