Hi all,
Firstly I'd better explain what I want to do, then I'll say what I've found on the net and here.
I'm buiding a flight simulator and I want to make some instruments that will look as though they are doing something.
The idea is that when I throw a two pole switch the servo will, (slowly) move a pointer to a given point. Then when the switch is closed again it will move back to the start position.
I've found various circuits using a simple 555 IC controlled by a variable resistor, I believe it might be possible to use two different resistors each side of the switch to get the servo to move to a set point. However I have no idea if this can be made to travel slowly rather than zipping stright to it's resting position.
Any help or suggestions would be appreciated. I should add that I'm quite a novice in this area, although I'm quite proficient in soldering.
Regards
Joe.
