Minimalist Shield for Arduino Printbots
by carlosgs, published
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).
----- Building tips -----
Â· This circuit can be made easily using pre-drilled PCB board.
Â· 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 -----
Â· 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
Â· Still need to make this PCB, but as far I can tell it will work.
Â· Analog pins can be used as digital:
------ A0 -> pin 14
------ A6 -> pin 19
Â· It is my first design using Kicad, please excuse my mistakes.
