Big chicks are approaching the day when you have to dress a Christmas tree. You can only choose traditional ornaments or supplement them with electronic gadgets. We present one of them - a glowing star.
The circuit is very fast - LEDs are steered from the counter with the so-called 'circulating one'. Due to the speed of clocking we have the illusion of flickering of all diodes. The impulse way of work guarantees long-term operation of the toy - if we use it from the battery.

The device is especially recommended as a Christmas tree
