I'd like to build a robotic arm...

hello

I recently decided to start a very similar project that your working on. I want to build a 4-axis of motion arm with the arduino. Im very new at this and have been trying to learn the basics of programming servos. I'm trying the tutorials off the arduino website yet there not quite doing it for me. Does any one know a good site to reference, or do they know a simple code where i can plug in any arbitrary angle and get a response from the servo. thanks.
