Receives from the hardware serial, sends to software serial. Receives from software serial, sends to hardware serial.
The circuit: * RX is digital pin 10 (connect to TX of other device) * TX is digital pin 11 (connect to RX of other device)
Note: Not all pins on the Mega and Mega 2560 support change interrupts, so only the following can be used for RX: 10, 11, 12, 13, 50, 51, 52, 53, 62, 63, 64, 65, 66, 67, 68, 69
Not all pins on the Leonardo support change interrupts, so only the following can be used for RX: 8, 9, 10, 11, 14 (MISO), 15 (SCK), 16 (MOSI).
