Perhaps the most important part of any Arduino is its capability to be programmed directly via a USB serial port. This feature enables you to program the Arduino without any special hardware, such as an AVRISP mkII. Ordinarily, microcontrollers rely on a dedicated piece of external hardware (such as the mkII) to serve as a programmer that connects your computer to the microcontroller you are trying to program. In the case of the Arduino, this programmer is essentially built into the board, instead of being a piece of external hardware. What's more, this gives you a direct connection to the ATmega integrated Universal Synchronous/Asynchronous Receiver and Transmitter (USART). Using this interface, you can send information between your host computer and the Arduino, or between the Arduino and other serial-enabled components (including other Arduinos).
Both this chapter and the following chapter will cover ...
