The 220v voltage will generate +12v voltage after reduction, rectification, stablization. The voltage will provide IC with working power. The other circuit will provide V2-V5 with working voltage. IC's pin 14 will beconnected to +12V power. Every time S is connected, the positive pulse will be put on IC's pin 14, which will make IC have a count. When S is connected and disconnected intermittently, IC's Y0-Y8 will output high level which will make the thyristor connected. Then the lights will have 8 different illumination states.
