Just checking a silly thing. I'm using the USB power, so I wonder if when I use an external power supply with more mA it will work better?
What happens is that when I light all my 16 blue LEDs the LCD display gets a bit dim. But not the LCD backlight. Its like the contrast gets weird somehow. Its a blue LCD with white digits. But the "white" gets a bit gray.
Is that the mA power output of the USB that is weak?
Just checking, not a really big deal for now...
