Colorful circulating decorative light circuit
Source: InternetPublisher:风向双子座 Keywords: clock control circuit filter Updated: 2020/09/21
Circuit working principle: 220 V AC voltage is stepped down by C1, stabilized by DW, rectified by VD , and filtered by
C2, and then a 12 V DC voltage is output for the control circuit to work. IC1 time base integrated
circuit NE555 and R1, Rp, C3 form an adjustable clock pulse generator to provide the required clock pulse signal for
the subsequent circuit .
