This circuit makes LED shining. It is widely used in toys. We make two lighting emitting diodes as toy-cat eyes. When the toy-cat's eyes are shining, that is interesting. This circuit uses NPN transistor, PNP transistor, LED, resistors and capacitor to form a flashing lamp circuit. This circuit operates at 3V. It requires two 1.5V batteries.
