Hello,
I am trying to trigger a 555 timer chip (hooked up as a one shot) using the output (pin 12) from a decade counter 4017B to the #2 trigger pin of the 555. When I hook the counter up to the 555 directly (straight wire) the 555 seems to be triggered all the time.
Info for the 4017B can be obtained here: **broken link removed**
I am using a 9V supply.
I would greatly appreciate any help in getting this to work, one way or another! I want to use the 555 to power up a relay for about a second.
Thanks!
Tom
