Can any1 help me with this IC . I'm trying to make a traffic light using IC 555 and 4017 .
I use multisim to create a design like the file i attached .
There not much problem when i run it in multisim .
Then I bought 2 IC : NE555P and HCF4017BE.
A problem is that when i do everything like in design, only 4th and 12th leg of IC 4017 light up my led . But it light up just like if i connect my led directly to the output of IC 555 . It feel like my 4017 IC only connect between leg 4, 12 and 14 and that all .
So any1 know what the problem here ?
Thank for your help and sorry because im bad at english .
