You need to go into the servo.c file, and adjust the minimum and
maximum frequencies the servo can handle. If you open servo.c, you'll find
instructions as to how to do this. You pretty much just have to adjust the
program to suit your servo, since all servos are a little different. One
you have those values set right, you should get just barely more than 180
degrees of movement - just make sure the servo doesn't make any strange
noises at 0 or 180 degrees, that means it's moving too far. Hope this
helps!
