I cannot get the code Jawduino to control my servo. I am using an arduino micro an ez-robot servo. I followed this tutorial http://buttonbanger.com/?page_id=137.
Please post your program and describe in as much detail as possible what happens when you run it.
If you are getting a compiler error message then please also post the error message.

PS .. When posting code please use the code button </>
so your code
looks like this
and is easy to copy to a text editor See How to use the Forum
I did try this on an arduino uno and an arduino micro.

Autiboy:
I did try this on an arduino uno and an arduino micro.
And what happened?
...R
The servo would not move.
I am not familiar with the SoftRcPulseOut library.
Why not use the regular Servo library?
If you really do need to use that library I suggest you start with a short program that does nothing except sweep the servo from side to side. In other words a version of the standard servo-sweep example.
...R
did you find an answer? Stuck also with several like errors.
I have not had time to play with the code but also i do not understand it very well so help would be apreciated.

It's about 3 months since your last Reply here. How much time do you need?
I'm reluctant to give up my time to help you if you are not prepare to invest yours!
And what code are you referring to when you say "the code"?
