But: I have a Surface RT and with Windows 8.1 the RFCOMM API can be used to establish a serial link to the Arduino. Arduino and Visual Studio It happens that my developing skills are quite limited to C# and when I had to develop some Kinect software with Processing in early 2012, I almost freaked out. Arduino code is written in C++ and the standard Arduino IDE is derived from the Processing IDE. Fortunately there’s the Visual Studio extension…
