For long distance communication we use the i2c. Typically there are three lines common to all the devices: The leonardo has 12 analog inputs, labeled a0 through a11, all of which can also be used as digital i/o.

For arduino leonardo, the pins on the icsp header are not connected to any of the digital i/o pins as they are.

Following figure shows the pinout of arduino leonardo. Usb jack, power jack and reset button are quite in line with each other and are surfaced on one side of the board. Spi pins 10 (ss), 11 (mosi), 12 (miso) and 13 (sck): These pins are used for spi communication.
