On your breadboard connect the MIDI circuit as follows: The collector is connected to a 220 ohm resistor which is connected to the second pin from the left on the back of the female midi connector (labelled pin 5).
The base is connected to a 10K ohm reistor which is connected to the serial data output pin of your microcontroller (ours is pin 1 aka TX aka the pin on the upper left).
There's a good chance that Samsung or LG could offer some wallet-breaking additions to their catalogs (think a clothes-refreshing wardrobe, digital blinds or maybe even a connected wine cellar) but it's always tough to pin down exactly what will appear next.
