Introduction: 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
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.
Step 2: STEP-2
Make the Base using a Hardboard of 8” x 8” with wooden batten nailed all around it.
Then fix the base of the Ic. 555, on the Hardboard platform, but not the Ic at this stage.
Solder wires to the legs of the Ic base, as per the Circuit diagram.
Solder 3 LED’s in series as per the Circuit.
Care to be taken to maintain POLARITY.
Step 3: STEP-3
The power supply is 12 volts DC.
Or 9 volts battery will also work, but the light output will be a little dim.
You can use a 12 volts DC Transformer.
Step 4: STEP-4
After soldering all the wires fix the 555 Ic. to its base.
Connect it to the power supply.
Switch ON and enjoy.
