I have an RGB LED matrix (though I am currently only using the red LEDs).
I am using two 4051s with an arduino and it all works fine.
All I am doing is iterating through each LED and turning it on and off with no delay to create the appearance they are all on at the same time.
For some reason the LEDs don't all have the same brightness. The ones along the bottom and right are the brightest and the ones along the top and the left are the least bright.
When I change the 32 LEDs on left side of the matrix with blue LEDs it still does the same... but the brighter right and bottom are now relative to the rectangles created by each colour on each side.
IE, both red and blue now have their own brighter edge and bottom.
Why is this happening please? I want to use PWM next to create blending colours but it will look rubbish if the brightness isn't precise... I am currently using digital high and low to turn them on/off.
THANKS!
