 +===== Open Sound Control =====
 +Open Sound Control (OSC) is a communication protocol optimized for modern network technology. An OSC message consists of an address, followed by one or two more arguments. The addresses consist of a hierarchical, URL-style name that begin with a forward-slash (“/”) character. The transmission units of this protocol are called packets and they will always possess a size with a multiple of 4. Compared to MIDI, OSC has the advantage of being able to process “Bundles” of messages that can occur simultaneously.

 +===== Inter-Integrated Circuit(I2C) =====
 +Inter-Integrated Circuit Protocol is a communication protocol that allows multiple peripheral devices to be controlled by one or more controller devices. It requires two lines a serial data line (SDA) and serial clock line (SCL) which each device connected on the bus requiring a unique address. Messages are split into two frames. The address frame indicates the peripheral where the data is being sent to and 8 bit data frames which contain the data being transmitted.
