Hi,
Been a while since I posted something.
I've got the 4017 to work just fine, finally =P. Added 2 bypass capacitors (10 uF and 47 uF) and, well, a 1k resistor from the clock pin of the 555 chip to the capacitor connected to the potentiometer (don't know how to explain it different =P).
So, I got that to work.
Added a 4081 chip for and-gates, also seems to work just fine.
But, when I add my second 4017 chip THAT one starts behaving odd.
Now the clock input from my second 4017 chip comes from the AND-gate from the 4081 chip.
Is this clock output useable or should I also connect this output to the capacitor connected to the potentiometer if you know what I mean?
