Hi crossroads,
So, I pugged in a wall adapter at 9 volts into the VIN port.
This time the voltage stayed much more consistent. For example:
Just running: 5.013
Running with USB monitor: 5.013
Running with USB monitor & LCD dark blue: 5.014
Running with USB monitor & LCD light blue: 5.014
So you can see that it's just changing by a VERY small amount. Do you think this is good enough? I plan to put this thing off the Arduino board, and place it in a breadboard. I was going to use an LM8705, but do you recommend this? Is there anything else that would be really good at keeping the voltage constant?
Thanks,
Cameron.
