Question on NeoPixel Painter project

by Dack9 on Fri Jun 12, 2015 5:37 pm

Hello! I assebled device in accordance with the project guide. It works perfectly but there is an issue with brightness adjustment. It is not adjusted at all (speed is corrected ok). Maybe I do anything wrong... Could anybody help and describe how brightness could be adjusted?

Sorry for disturbing! I digged the rootcouse of the issue. Maybe it will be usefull for somebody... At the second pass, to brighness variable "b" assigns counted maximum brighness value. That's why every time brightness is always at maximum counted value. To operate program correctly, it is required to delete (or comment) line "b = minBrightness".

Wonderful info and images!!! I am currently building this NeoPixel Painter project. Did everything, the wiring, the code, etc work correctly? I saw your post about brightness, ( minBrightness ). Not sure I understand it, but will see it it works for me. Any advice or suggestions is appreciated. Guess you can email me at kerrylawrence@imonmail.com

The brightness issue was fixed in the code a while back; latest is on Github as always.
