 ### Communication

-The Robot has a number of facilities for communicating with a computer, another Arduino, or other microcontrollers. The ATmega32U4 provides UART TTL (5V) serial communication, which is available on digital the 10-pin board-to-board connector. The 32U4 also allows for serial (CDC) communication over USB and appears as a virtual com port to software on the computer. The chip also acts as a full speed USB 2.0 device, using standard USB COM drivers. [On Windows, a .inf file is required](http://arduino.cc/en/Guide/Windows#toc4). The Arduino software includes a serial monitor which allows simple textual data to be sent to and from the Robot board. The RX (LED1) and TX LEDs on the board will flash when data is being transmitted via the USB connection to the computer (but not for serial communication between boards). *Each one of the boards has a separate USB product identifier and will show up as different ports on you IDE.* *Make sure you choose the right one when programming.* The ATmega32U4 also supports I2C (TWI) and SPI communication. The Arduino software includes a Wire library to simplify use of the I2C bus; see the [documentation](https://www.arduino.cc/en/Reference/Wire) for details. For SPI communication, use the [SPI library](hhttps://docs.arduino.cc/language-reference/en/functions/communication/SPI/).
