Hello - been reading up on servo tester/controller circuits using the 555. Here is one I am considering. They use a pot and I assume that is used to operate the servo through a range.
Well, say you have a design that requires a servo to travel 90 degrees - and have 2 pts. zero and 90.
Can you first establish two points using the POT and then substitute with 2 resistors and a switch?
Also, if a given servo is rated to travel say, 60 degrees in .09 ms will the 555 servo controller circuits be able to run the servo that fast? Or putting it another way how does the 555 circuit above control and handle speed of a given servo?
Lastly, if you needed to incorporate a delay into the circuit how would that be done if it could be done? Example go from 0 to 90, pause for 5 seconds return to 0...
