Summary

Simple shield board that allows to connect servo-motors and other devices (like sensors) to the analog pins of an Arduino board (UNO or MEGA).
It also has a connector for the batteries.

You can use it in printbots like the MiniSkybot or the ArduSnake! (http://www.thingiverse.com/tag:printbot).

Instructions

----- Building tips -----
· This circuit can be made easily using pre-drilled PCB board.
· You can push the header pins all the way trough to be able to solder them on the other side of the PCB, even with one-layer designs like this one.

----- Notes -----
· I have made some tests with an ArduSnake, using a previous version of the same circuit. Here is a video: https://www.youtube.com/watch?v=oEkTYmGqIWo
· Still need to make this PCB, but as far I can tell it will work.
· Analog pins can be used as digital:
------ A0 -> pin 14
------ ···
------ A6 -> pin 19
· It is my first design using Kicad, please excuse my mistakes.

----- Progress -----
· 16/05/12 Built OK, here is a video: http://youtu.be/zC5MKcnZ27Q
· 02/05/12 Made a paper version and uploaded pictures
· 30/04/12 Uploaded version 1.0 of the board
