Servo and pwm

Make sure you're wearing safety glasses before powering-up that servo with a
2N3904 low-side switch...;o}

An FET that can handle your servos stall current might be a better choice?

Thanks Bruce,

The servo is one of those micro-miniature jobs. I tried the same code on a "regular" hobby servo and it works like a charm without any switching. The regular one does not even move when you put power to it, the mini job can spin almost 1/2 way around. Not a cycle or two.....

Cheers

Hi Gary,

I had one of those micro servos a few years back that did pretty much the same thing.

It had a severe twitch under certain circumstances too as I recall. Can't remember exactly
why, but it was a funky servo. I think it was a BlueBird brand? Can't remember. I blew it up
goofing around, and never bothered replacing it.

Its down to the indidual servo buddy, the experiances i have had is the nice and cheap servos have alot of start up movement.... I got a cheap load of servos from ebay and they all have this problem. I also have another servo which i got from a friend at work which is of a higher wuality that doesnt have the issue
