Autopump is a small project to create an Arduino powered automatic compressed air controller. The controller has an LCD screen and two button interface. Two automatic valves and a pressure transmitter make it possible to achieve accurate control on the target pressure. The original purpose to build such a controller was to make it possible to automatically pump soccer balls, although the controller of course can be used for any purpose.

Below is a rendering of the Arduino UNO shield that is needed to control autopump. The shield connects all peripherals to the Arduino board.

All sourcecode is released under GPL2 license and the hardware is released under the OSHW.
