ADABOX009: Make sure your Hallowing has a good power supply

by jcalvin on Thu Oct 11, 2018 3:41 pm

I was seeing some odd behavior with my Hallowing (backlight dimming as I raised the brightness of the neopixels, sound when there shouldn't be any, and other things). Took some poking around, but I finally determined that it was an inadequate power supply (USB off an old hub on a Mac).

All of the odd behaviors disappeared once that was fixed.

Moral: always check the power supply first when odd things are occurring.

Thanks for posting your findings. USB ports are usually pretty stable sources of power. But when odd things start to happen, you need to go back to the beginning and verify
