Phideaux said:I'm stumped. I know I'm not the sharpest tool in the shed, but while
I'm on vacation, I wanted to develop what I thought was a simple
circuit. I need a single pulse generator that will output one single
pulse each time a switch is thrown. Here is a link to the sketch of
what I thought should work.
Can anyone enlighten me as to why this isn't working? Values for the
circuit are R1=1K R2=1M C=0.04uF I don't have an o-scope, so I've
sent the output to an r/s latch to see if it is indeed triggering an
output. The latch works just fine, the rest doesn't seem to be
functioning. Thanks for any help you can give me, including
psycological at this point.
The problem might be due to contact bounce on your switch. You need a clean
transition from ground to + 12 volts on the input.
