#### Rover with Arduino Nano:

The Arduino Nano is a highly adaptable microcontroller with many I/O ports. The default I2C ports on the Nano are A4 (SDA) and A5 (SCL). The rover can use I2C to easily communicate with an Arduino. This enables the rover to access all of the I/O ports on the Nano and use these as external sensor ports. In the example above, the rover uses an Arduino Nano to receive data from a line sensor array.
