I'm very new to this elecrronic stuff, but I was able to do what I
needed with the 555 timer, but I am lost with trying to get the 556 to
do what I need.
I'm using a 556 timer and below is what I would like to happen. If
anyone can make up a schematic or something to get me going in the
right direction I would surely appreciate it. Please contact me if
more information is needed.
With Mercury switch closed (1st timer)
Turns on Buzzer for 2 seconds (which I want) unless switch stays
closed
Gives power to second timer (momentary switch) even if the 2 seconds
on the 1st timer has elapsed.
With Momentary switch closed (2cd timer)
Sends power to a LED
Continues to stay closed till 1st timer switch is activated again
Thank You for Your Time,
Dave
