After a little bit of playing around with Arduino I have made my first program or sketch as they call them at the Arduino web site. It is a program for slowing down servo movement. It is intended to control servos that rotates the main guns on a Yamato model.
Here is a recording I made with one servo attached:
It may be possible to avoid the initial servo movement by adding pull down resistors. I haven't tried that yet. This initial servo movement isn't shown in the video.
