Picture of DANCING LED's

I made this Instructable for my grandson who is interested in electronics, and is 9 years old.

Here I have used a 555 timer Ic. to make the LED’s dance.

It is a simple Project for beginners who like to work with LED’s.


Step 1: STEP-1

Picture of STEP-1


Ic 555 with base, One.

Resistor 33k, One.

Resistor 100 Ohms, Eight.

Capacitor 10uf  to 100uf, One.

White LED’s, Four.

Blue LED’s, Four.

The Base made of Hard board, 8” x  8”

On / OFF switch, One.

Use thin wires split out from an old Hard disk of Floppy disk cable.

I can't get my leds to blink, they just light up without blinking. I tried changing the capacitor and nothing :/

Check your connection to the Ic 555. The No. 3 point directly goes to point 2 & 6 through a 33k resistor to the Condenser. It does not connect points 8&4.

Excellent, but i am confused as you have 24 leds on the schematic, but your list only says 4 of each? white and blue?

White LED's 3x4=12
Blue LED's 3x4=12
12+12=24 LED's.

Nice project, except I don't see a video?

Hi Kiteman,
I have a video but I don't know how to load it to my Project.
You will notice that non of my Projects have a video,

loading video into your instructable is easy:

  • copy your video to your computer
  • upload video to youtube
  • copy embed code from youtube into instructable
good luck.

As usual, nice job & good Instructable.  I think the grand-kids would like this, but they are a little too young right now (2&3).  I have everything needed to build this in my stash.  I usually buy in bulk from Singapore off of eBay.  They take awhile to get here, but the prices can't be beat.  I just wish I had your creativity.

Interesting, Dipankar.

I could not see the video.
I couldn't get the video to work (Likely my fault), but the idea is a delight!

I can use this in part of the low-speed vehicle triangle sign to draw attention.

Very cool use of the 555 chip!
