Bit of a dumb question...
I have this 4017 decade counter chip that I want to use, but instead of
hooking up a clock signal (like from a 555 timer IC) to the CLK pin, I want
to be able to control the 4017 using a push switch.
At the moment, I have the switch hooked up to +Vcc with a 100K pull-down
resistor connected to GND. So when the switch is not activated, it receives
a low input, and when the switch is being pushed, it receives a high input.
But every time I press the button, the 4017 is not changing its output
smoothly.... it's skipping and changing at various speeds as I press and
release the switch. What am I doing wrong? Tried changing value of the
resistor but no joy.
Thank you
