Arduino Project for a young
one with 3 servos.
Just a starter pack from Radio Shack.
The microcontroller bord is a standard Arduino micro board. The project just requires a Phillips screwdriver. The USB cable is good for electric power when connected and to upload the sketches after it has been put together with a graphical program environment.
The only negative was that there is little mentioned about the servo's - how large an angle they can move. You choose to wide an angle and the physical will not follow the programmed path. That was rather annoying for a little one when it does not work initially.
