When S1 is connected, 220v voltage will generate +5V voltage after reduction, rectification,filtrition, which will be sent to IC,V0-V7. When IC begins to work, Y0-Y7 will output high level pulse, and V0-V7 will be connected. VT0-VT7 will be connected. 8 circuit illuminations will be turned on. When any transistor of V0-V7 is connected, its LED will be illuminated as monitor. IC's OSCR terminal is connected with RP. When RP's resistance value is changed, the twinkle frequency of the illuminations will be changed.
