I'm trying to create a circuit that will make the output go high some amount of time after a 5V control signal goes high. That delay time may vary by application, so I'll use a potentiometer in place of the 249k resistor. I'm thinking of using a 555 timer in monostable with a 5V power supply. Below is the circuit I came up with, and I think it will work, it just seems like I might be coming up with something that's overly complicated because I'm a n00b. Is this a good approach, or is there a simpler/more effective way to do it?
EDIT: One other requirement that I neglected to mention. I want the delayed output to go high after some time, but I also want it to go back low immediately after the input goes low. I feel like that might cause a problem with using an RC filter.
