Four-way flashing light string circuit (4)

It is a network flashing light string maker using an application-specific integrated circuit . It has four outputs;
it can control 16 patterns in a single-key cycle, and can select 16 segments or the first 8 segments and the last 8 segments. The circuit also features photoresistor
R1. , can make the light string automatically turn off during the day and flash at night; this circuit is very suitable for Christmas tree color
control.
    ['S980I based Wuxi China Resources Semico Microelectronics Co., Ltd. (http://www.semico.com.cn)
product circuit adopts DIJrJ-I-1 standard package, and can also be customized with black paste soft package according to customer requirements , the power supply
voltage range used is 2-7V. Chips 1, 1-1, and 4 are output terminals that can directly drive thyristors, and KEY is a keying input terminal.
Each key press can change the color cycle pattern. Jt has 16 patterns, as shown in Table 8 2:
    This circuit is CS98. The () PT end of 1 is left floating, so it can automatically cycle through 16 patterns. Each time the button SL is pressed 3 times,
the colored light string El-E4 changes as shown in Table 8 2. III can use MC; 45 type photoresistor, which can be used during the day. Automatically
turn off all colored lights to extinguish them. Thyristor type MC, R100-8. Oscillation resistor R: and the step-down current limiting
resistor should be changed as necessary according to the current and L frequency of the alternating current. When using a 110V, 60Hz alternating current
grid, R. The recommended value is 25-33kn: R. The recommended value is 68-150kfl. When using 220V,/50Hz AC
power grid, R. The recommended value is 33-39kfl; R. The recommended value is] 50-300kn.
