OK, I tried searching the forum but came up empty. Still learning so forgive me if I'm asking a question that is straight forward. I've also done a bunch of reading on 555/556 timers and flip flops.
I'm trying to take a digital input trigger (5v), create a one shot timed pulse that lasts say 1.5 seconds, and prevent the trigger from generating any other pulses until a manual reset occurs. The pulse will drive a relay coil. I'd also like to play around with the pulse timing to tune the range from .5-2 seconds. Once I figure it out I can use the same design to gate the trigger source for a period of time, say 10 seconds, to prevent it from sending the intial trigger.
I'm thinking there's a 555/556 timer in there somewhere with a flip flop to do some latching that's reset with a button. I'm also thinking a variable resistor can give me some adjustment on the timing. I'm just drawing a blank on how to hook these up. I'm also wondering if I should be using different components or there's something out there that will do the job for me in one IC.
Any help would be appreciated.
