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.

SEE THE VIDEO.

Step 1 STEP-1

 PART LIST

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.

Please CHECK the circuit, and see if the Connections to the Timer Ic 555 is OK.

There are no other circuit with me.

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

[Dipankar]

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

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

[Dipankar]

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,
HELP URGENTLY REQUIRED.
THANKS.

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!
