In my own work, I don't use technologies in a flashy way, I use it like a possible tool only. It is often invisible or really discrete. This is only an aesthetic choice. Try to have a quick look to a few of them because they are very different.
Here some of my work using Arduino, Teensy etc...
I do sometime live code, either for cyberperformances or live performance
I often use live electronics in my work. Either for improvisation or composition or even in installation. Most of the time, I use Max/MSP for my live electronics works
