I'm kind of new to this electronics stuff. I took a class years ago
and have a pretty good idea of how basic circuits work. I don't have a
clue about IC's.
I am working on a little project which I don't know how to set up. I
am using a 4.5VDC battery power source with a mercury switch that will
be used to close the circuit and sound a buzzer. What is happening is
that when the circuit closes the mercury will continue to slosh around
and sound the buzzer multiple times. What I would like to happen is
when the circuit closes it sounds the buzzer for a split second, opens
and stays open for a determined amount of time (3sec) even if the
mercury closes the circuit again. I was told I could use a 555 or 556
timer to accomplish that. I purchased both timers and set up a couple
basic circuits that I saw on the internet. I've played around with the
timers for a long time but I just can't figure out how to use them to
accomplish my above goal.
I would surely appreciate any information or what I would need to
purchase to get my circuit working. If you have any questions I would
be happy to answer them. You can reach me by e-mail [email protected]
or phone 480-763-8199.
Thanks for Your Time,
