Here is what I need to do: I need to connect 2 arduinos using 4 wires. Easy, right? The tricky part is that they need to communicate despite the way these 4 wires are connected. Let me explain: 4 I/O pins on one arduino will be connected to 4 I/O pins on the other arduino, but the communication MU…
