I am interested in putting together a controller to trigger cameras and associated gear. So I thought I would use the Arduino Mini Pro with a display that uses little power but can be seen running, so I didn't go for backlit diplsays. It will switch optos on and off to control the cameras. So I found this display that uses only 2ma. http://www.pololu.com/catalog/product/773/specs
Would this work? I just want it to run for like a week on a set of AA batteries.
