Default Servo Controller

I was wondering if anyone knew how to generate a signal to control a servo. I'm thinking like a box that the servo can plug into and use a knob to position the servo arm.

I read online that they respond to square wave pulses and the longer the pulse the more it will turn. This is the site.

How do you adjust the pulse length? What kind of circuit would i need to build?

1.5ms is neutral 1ms is ''left' 2ms is 'right' Give or take of course. Generating them isn't easy without 'expensive' equipment, at least for what it does. For what purpose would you need to generate such a circuit?

I would use the servo to control a hydrostatic transmission in a large scale train.

I found a few circuits to generate square waves, but i'm not sure if it will work. I found many control boards that connect through your computer.

We offer just such a controller. Take a look at our site ServoCity.com. Our unit will control 2 servos just as you explained.
