Typical application circuit diagram as shown in figure is ML - 01 g. Figure in the IC is 14 feet dual in integrated circuit, function arrangement and the pin description as shown in table. Use 3 v to 6 v dc power supply. Figure in the resistance ROSC Ω nominal value 270 k. The size of the appropriate change ROSC. Can adjust the rhythm of IC output signal. 470 Ω resistor R1 resistance value, to provide appropriate working point triode. Capacitance C2 104 pf. Improve the sound quality effect; C1 is 220 u F electrolytic capacitor, the filter and the effect of decoupling, NPN transistor T1 for TT - 8050 type low power triode, IC output of audio signal would be enlarged to promote speakers work. S2 is playing music trigger switch, the flag-raising S4 for the flag button switch. The flag-raising, press S2. Start working circuit. The speaker played the national anthem of the People's Republic of China. At the same time IC 9 feet are level of output signals. Driving motor, change gear driving device synchronization flag of raising national flag. The national anthem was over, the national flag just ascended to the flagpole. Flag, start the S4, the circuit no music. IC 8 feet are level of output signals. Descending drive flag electromechanical device, the national flag.
