I was digging through our electronics drawers and i found a 4017 chip. I looked up the pin assignments and found a simple circuit where a 4093 was set up to pulse the 4017 to make the LED's "chase".
In the circuit they had the reset and the enable going right to the neg and all the appropriate LED's/resistors going from the outputs to neg.
When I set up the circuit, I had everything hooked up as they did with the exception of the 4093. (We jsut didn't have one in the lab). I also used a 5v power source to pin 16 and 8 appropriately. For the clock input, I tried using a tactile button to "pulse" a signal to make the lights....well....do something at least but it didn't work. Why is this?
