I havev 9 the oldest MindStorms RCXs with brickOS and I want to full use them, but RCX only have 3 input ports and 3 output ports, so if arduino can receive or send IR LNP from or to RCX, that RCX will be great. The LNP is Lego Network Protocol, you can refer it here http://cs.brown.edu/courses/cs1…

Can I use arduino to communicate with Lego RCX?
