So if the collector is tied to GND, then the base voltage always flows out of the emitter?
Now I'm confused about how multiplexing is supposed to work. I was under the impression that you could use common bases horizontally and common collectors vertically on a grid of transistors and thus use an x,y coordinate to cause the emitter on the relevant transistor to supply the collector current to one of many LEDs.
Do you think there is any way I can get around this without tearing up and starting again?
The real world circuit uses 5 arduino pins to source and sink 5v.
The long explanation that I was hoping to avoid...
Does anyone have an opinion on my idea of using higher rated resistors on the transistor bases, would that fix the problem?
