Well, i bought these Tri-Colour LEDs today (red green + yellow) - but they only have 3 poles on them?
Apparently the middle pole is the common anode (judging by the length compared to the others) and the other 2 are cathodes. I can get the Red and green to show - but i don't know how to get yellow?
