The operating circuit of the led light generally can not adjust the speed of operation. It causes boring monotony. Resulting in an idea to build this circuit. This circuit can adjust the speed of the led light as needed. It makes this circuit can be used more versatile.
The operation of the circuit is divided into two parts: frequency generators. And the screen. By the frequency generator IC1 it contains a timer circuit number Ic 555 and a frequency generator. Defined by R1, VR1 and C1 will be the output signal on pin 3 of IC1 sent to the display section.
In the display section consists of IC2, a number CD4017 IC counter circuit is shown by the voltage on pin 3, 2, 4, 7, 10, 1 and 5, respectively, each pin. The speed depends on the frequency count obtained from pin 14 of IC2, which we can adjust VR1 adjusts the frequency of the part of the frequency generator.
It can be understood in the following video:
