Dancing Lights

Here is a simple dancing light circuit based on NE555 (IC1) & CD4017 (IC2) . The IC1 is wired as an astable multivariator to provide the clock pulses for the CD4017. For each clock pulse receiving at the clock input (pin14) of I.C. CD4017, the outputs Q0 to Q9 (refer pin diagram of CD 4017) becomes high one by one alternatively. The LEDs connected to these pins glow in the same fashion to give a dancing effect. The speed of the dancing LEDs depend on the frequency of the clock pulses generated by the IC1.

Note:-

1. The I.C. should be mounted on I.C. base
2. Using different color of LEDs would produce better visual effects
3. For testing use a breadboard.
