DONT connect those eye led panels DIRECTLY to your Arduino..
you are gonna blow it!! (the Arduino..not the leds)
you are trying to pull more current than the pin can safely give!!!!!
it cant be any more clear than the two diagrams myself and memebr posted..
and unless your LEDS are rated for around 2.1-2.2 vF.. then its incorrect
Did you try to meter by using JUST the blink (put a LONG delay in there).. and see what the meter says?
No i havent tried that. But does it really matter now? As you said: i should not power it directly from the arduino or i will blow it.
So i need to connect them using a transistor functioning as a switch.
I'll continue tomorrow. Over here its bedtime right now.
Ps. I tried to draw a scematic using frizzing. Damn more difficult then it looks.
