    This prototype is with a Arduino Uno, but i/o ports are all used now. I’m waiting for a Mega 2560 Pro Mini to arrive. Programming it with Mobiflight!

      Can you use multiplexers? I am using 5 shift registers and MMjoy to get 40 ports.

        That was my initial plan, until I found out about the 2560 pro mini with all those ports available out of the box - for only $9,- …

          That is an impressive amount of I/O indeed!
