Well odds are no i won't need the R2, R4 or C1, since those inputs are pulled high, be it with just a 330ohm resistor with a possible open collector (? need to check) Mosfet / power transistor based trigger to ground and it will not be a quick pulse either.When the input signal 2 is come from a switch then R2 is the pull low resistor when the switch is off, the R3 and C1 are the switch debounce, if the input signal 2 is not come from the switch but a logical signal then you don't need the R2 and C1, if the input signal 1 also is not come from a switch then you don't need R4, if you can accept the original status of voltage changing then you don't need the C2 or change to a smaller as 10uF/10V.
The output voltage that you used the voltage divider, I didn't change the values of resistors and I just thought that you can calculate by yourself, it is not so hard.
Also i like your thoughts on using C2, may up it a bit for a more gradual change thou?
And i'm not blaming you on the Output voltage change side, i know you used my numbers, but those were done using a parallel resistor and voltage divider calculators and and trying to get as close as i can via "standard" resistors. So possibly i'll need @330 ohm resistor and a 100ohm pot to fine tune the resistance to dial in a number that would be correct.
Since this one seems to work, and decent well to at this time. It's time to venture onto another option and see what that does. Hey i want to try out everyone's thoughts, it's only fair, if one puts effort to try and help me, it's only fair for me to try what you put together.
Thank you to all again
