Hi Guys, first post here so ill try and be as detailed as possible as to what I am trying to do
I need to build a servo controller to control a 6V servo with a source voltage of 12V. The servo needs to move from position A to position B when a trigger voltage (12V) is applied.
So I have a constant 12V to feed the circuit, and by default would put the servo in position A. I then apply a trigger voltage to the circuit which moves the servo to position B. then if I remove the trigger voltage the servo reverts to position A. The circuit also needs to remember these positions with total power loss.
If anybody could help that would be great I'm capable of assembling the circuits, but don't have the knowledge to design them. I did a google for servo controller designs and the most popular method seems to be with a 555 timer, but these all seem to use 5V (I need to run off 12V and control a 6V servo) and just use a pot to move the servo. I thought maybe I could run two of the 555 designs in parallel with a relay so to switch between when the trigger is applied, and replace the pots with resistors of the right value but I'm not sure it would work..
TIA
