I have a Radio Shack camera and the SparkFun 16x2 LCD hooked up in my project. I added a couple more LEDs and a push button and noticed now my LCD fades to almost off (backlight is still lit) and comes back right away when I disconnect the camera shield.
Is there too much power drain at this point for me to have these in the same project side-by-side, and if so, would it be better for me to isolate and/or supply 5V to the camera shield separately? I suppose now would be a good time to play with my new variable voltage regulator...
