Here I solved most of my doubts from this site.Thanks to you all and cos of that I come this far.
1 . I wanna cycle through the various color LEDs using clap .
2 . I use a switch to cycle through the effects of LED so I used another 4017 to switch the power supply through 555 and the output of the 555 is amplified using bc547. I hope so.
I made the exact same connection. 8 and 13 to ground and 16 to +ve source. That's it. but LED randomly started glowing . If i apply ground to LED's ground it acts pretty normal but it automatically cycles through various pins. and each pins contains 3 LED in series . incl rainbow LED. I'm using 9v 6f22 battery.
