Ok, I have a really basic Transistor Servo Circuit, to make the Servo move in a CW and CCW direction.


-I would really like a circuit that will sense the end stop of the CW direction, and then send the Servo in a CCW Direction, until it hits its end stop, and then continues, waving back and forth.

-I would like the end of the direction sensed by a IR reflective sensor, If possible (as I do not wish to use mechanical sensors.)

-I know that there are "Servo Exerciser's" that are cheap. and do this, but when they power up, they do not power up to this function, but another function.

-I dont care the Voltage required, but the servo works best at 6VDC

Thank you very much for any help, in advance.

I dont mind using a relay to do the switching, just would prefer a non-contact sensing option, Thanks!

By 'Servo' what form does it take?
RC? PID motion type?
Is it, and/or the load capable of immediate reverse?
Have you looked at the option of uni-direction mechanism similar to auto wipers method.

I just wish to use a standard "R.C. Hobby Grade" Rotation Servo, such as the SG90

No more, or similar as a IR device which usually require two wired devices.?

Ok, I can use a Prox Sensor, f you include it in a diagram, no problem

Start learning basic Arduino programming.
They are made for things like this.
If you learn about promini or nano, small size and modular also.
Even picaxe if you prefer.
