Joystick interface for servoes

Hey folks!

I'm thinking about building a interface for an old joystick.

The interface is supposed to control a servo, and as far as i can tell the servoes runs with PWM, so i need an interface that can make these pulses. I've searched on google, and found: https://www.4qdtec.com/jsi.html but i cant figure out, if this can do the trick. I just want it to do pulses for me;
move the joystick forward, and i moves the servo one way, and reverse the other way.

Can any of you tell me if this will do the trick?

Thx a lot guys

I don't think that circuit will help you if this is an R/C hobby servo.

Do you know the resistance of the pot(s) in your joystick?

There are a lot of circuits out there to "test" or "exercise" servos. Many based on PIC's, but also on LM555 ICs. One of these might be adaptable to your joystick.

Here's an old thread with some info you might find useful ...

Thx a lot guys

That helped me out just fine.

I actually found one on google: http://www.geocities.com/bourbonstreet/3220/servobasics.html

I don't know what the resistance in my joystick is yet, but I'll update when I have more info.


Oh... And sorry for my bad english, not guite the language I use every day ;-)
