So I have two Arduinos. One is a Duemilanove and one is a Nano. The Duemilanove receives DMX data, and I want to send 5 channels of the data to the Nano to send over the serial port to my computer. I can't use the Duemilanove to do that, because it's communicating with the timer chip (for DMX receive). I don't think I can use digital read/write and connect 5 wires to the digital outs of one to the digital ins on the other right? Because digitalRead/Write can only produce HIGH and LOW.
