When it comes to LED flashing, blinking, or sequencing circuits, no one can beat the glamour of Dancing LEDs. Meanwhile, the Dancing LED circuit utilizes for enlivening decoration purposes, however, it looks excellent when the interconnected LEDs gleam in successive ways. We can make numerous Dancing LED Patterns for decoration purposes.

In this specific circuit, we have created a unique LED lighting pattern in which 6 LEDs are enlightening in a forward and inverse manner. Thus, to make this circuit, we have fundamentally utilized 555 timer IC and 4017 IC and not many other components. So, let’s start fabricating this astonishing circuit!

Dancing LEDs Circuit

Working Explanation

Accordingly, we have associated 6 LEDs with the yield Q0 to Q5; presently, after 6 LEDs, we have to shine them in reverse order. To accomplish this, we have associated center 4 LEDs to the yield Q6-Q9 as well. Henceforth, the center 4 LEDs are associated with the two yields I. e. Q1-Q4 and Q6-Q9. Diodes have been utilized to interface center 4 LEDs, to forestall the converse current stream, with the goal that when one yield is HIGH, the current can not pass through the other connected output pins.

So now, at last, LED 1 to 6 sparkles, however, LED 5 to 2 shines in reverse order, and afterward again, LED 1 to 6 gleams, then 5 – 2 also, and this pattern repeats consecutively. 

Applications and Uses

The Dancing LED circuit might be used for several purposes:

  • It can be used as any indicator lights
  • Signaling purposes
  • Decoration
  • Special occasion lighting etc
