Let me present my next round of noob question to keep you all on your toes....
I'm trying to add AmandaLDR to my next project. Two eyes in front, two on the bottom for edge detection. The problem is that digital outs and space for wires are limited, so I was hoping to combine my SuperBright LEDs into a single output if at all possible.
When I connected the anode of one LED to the cathode of the next LED, only the second LED would work. Ditto for the third of 3, etc.
1. Is that because of the forward voltage of the LEDs?
