Just for fun i connected 40174 Ic's clock input from 555 Astable mode output.
But the problem is any of the output LED's glow up without even being connected to any Logic 1 or 0. LED's light up and down randomly without sequence.
I think this maybe because i left inputs open. But what shell i do??.
Also one thing when LED's are on they flicker with 555 frequency , Though i connected Decoupling capacitor so that it does not happen.
